Interpretation of Results
The objective of the experiment, entitled Newton’s Second Law of Motion, is to verify the direct proportionality of acceleration and net force if the mass of the body is constant and to verify the inverse proportionality of acceleration and mass if the net force is constant. It is now clearly explained and proven that Newton’s second law of motion is true. By experiments, the law is proved. All data produced results parallel to what Newton states. We can say that the acceleration is directly proportional to the net force if the mass of the body is constant. The acceleration increases as the net force increases. The acceleration is inversely proportional to the mass if the net force is constant. The acceleration decreases as the mass of an object increases.

We also found out that the change in net force greatly affects the acceleration than of the change in mass of an object. This is proved by the third part of the experiment. When both the mass of the object and the net force increases, the change in net force will produce greater effect on the acceleration. We can also say that the acceleration will follow the direction of the net force. mass| net force| acceleration|

Newton’s second law of motion, the most important and useful of the three, establishes a relationship between the unbalanced force applied to an object and the resultant acceleration of the object. This relationship states that an unbalanced force acting on an object produces an acceleration that is in direction of the force, and inversely proportional to the mass of the object. In other words, force equals mass times acceleration, or F = ma. Thus, a given force will accelerate an object of small mass more rapidly than it will on object of larger mass. Similarly doubling the applied force produces...

...Analysis
The experiment that was conducted was primarily about Newton’ssecondlaw of motion. Newton’ssecondlaw of motion states that a net force is required for a body to have acceleration. If a net force is applied on an object, then the object will accelerate with respect to the direction of the said force. The body’s acceleration is directly proportional to the net force and inversely proportional to its mass. The experiment conducted was used to verify the relationships specified in Newton’ssecondlaw of motion.
There were 3 trials, and these were:
A. Constant Mass, Varying Net Force
B. Varying Mass, Constant Net Force
C. Varying Mass, Varying Net Force
In the said experiment, the formula used for the calculation of the experimental acceleration was:
As for the accepted value, the formula used was:
For the first trial, the net force changes when the mass of the mass hanger changes. The net force, N, is obtained by the equation of m2g, where m2 represents the hanging mass, and g is the constant gravitational pull, which is 9.8m/s2. The results of part A can be seen in the table below.

...E104: NEWTON’SSECONDLAW OF MOTION
METHODOLOGY
In Part A of the experiment (Constant Mass, Changing Net Force), place the dynamics track on the laboratory table. Make sure that it is horizontal by placing the dynamics cart on the track. If the dynamics cart does not move, then the track is already horizontal. Otherwise, make the necessary adjustments. Get the mass of the dynamics cart. Write this under m1 in Table 1. Set the first photogate at the 20-cm mark of the dynamics track and the second photogate at the 70-cm track. This is the distance in which the cart can travel. Write this under S in Table 1. Plug the first photogate to the number 1 slot of the smart timer and the second photogate to the number 2 slot. Ask for help from your instructor if you have difficulty in setting up the photogates and the smart timer. Set the smart timer by pressing the “Select Measurement” button until it shows “Time:”. Set the mode by pressing the “Select Mode” button until it shows “Time: Two Gates”. Tie one end of the string to the cart and the other end to the weight hanger. Set the dynamics cart on one end of the track and the weight hanger over the pulley. Refer to setup. (See Figures 2 and 3). For the first trial, use a total mass of 20g for the hanging weight. Write this under m2 in Table 1. Release the cart. Read the time of travel from the smart timer. Write the time of travel under t in...

...NEWTON’SLAWS OF MOTIONNewton's First Law of Motion
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
There are two parts to this statement - one that predicts the behavior of stationary objects and the other that predicts the behavior of moving objects. The two parts are summarized in the following diagram.
The behavior of all objects can be described by saying that objects tend to "keep on doing what they're doing" (unless acted upon by an unbalanced force). If at rest, they will continue in this same state of rest. If in motion with an eastward velocity of 5 m/s, they will continue in this same state of motion (5 m/s, East). If in motion with a leftward velocity of 2 m/s, they will continue in this same state of motion (2 m/s, left). The state of motion of an object is maintained as long as the object is not acted upon by an unbalanced force. All objects resist changes in their state of motion - they tend to "keep on doing what they're doing."
EXAMPLES:
1. Suppose that you filled a baking dish to the rim with water and walked around an oval track making an attempt to complete a lap in the least amount of time. The water would have a tendency to spill from...

...Newton published what are known today as Newton's three laws of motion. If these laws didn't exist, motion and life would not exist. His three laws are accurately relative to what "normal" speeds are on earth.
Newton's first law is most commonly referred to as the law of inertia. The law states that an object that is at rest will stay at rest unless an unbalanced force acts upon it, and vice-versa. If an object is moving and there is no force to move the object in a different direction, then the said object will move in the path it's in for an indefinite period of time. Newton'slaw of inertia is only relative to what people experience on earth, though it is still considered a law for it is not relative to the human condition to regularly find yourself or others moving at 600 MPH while walking. As an example, suppose that a meteor is hurtling towards planet earth's precious moon, and will obliterate it into a bunch of tiny space rocks that will mess up the ocean tides and NASA's moon research. That meteor will continue to hurtle until it comes into contact with a force that will either change its direction or stop its motion. Unless the Internationale Space Station steers itself into position, the moon would be the force to stop the meteor from traveling through...

...P hysics 2 06 Example P roblems Newton’ s Laws of Motion
Problem 1 . A) What is the direction of the acceleration of an object that is slowing down while heading northward? Answer : The acceleration would be southward since the net force required to cause this acceleration would be southward. The change in velocity is directed southward. B) What is the acceleration of an object thrown straight up in the air, near the surface of the earth, at the very top of its ﬂight? Answer : The acceleration is downwards at 9. 8 m/s 2 . The only force acting on the object at the top of its ﬂight is the gravitational force^ so the object is in free fall. The object is changing velocity as it passes through zero velocity. C) What is the direction of the net force acting on an object that is moving in a circle with constant speed. Answer : As shown in the chapter 3 text, the acceleration of such an object is directed towards the center of the circle so the net force on the object must also be directed towards the center of the circle. D) Is it possible to round a corner with constant velocity? Explain! Answer : No, to round a corner one must change direction and so one must change velocity. E) According to Newton’ s SecondLaw, more massive objects tend to be harder to accelerate. Why then do all objects, regardless of mass accelerate at the same rate when in free fall? Answer: Although more massive objects are harder to accelerate,...

...Newton’ssecondlaw of motion (Car vs Suv)
According to newton’ssecondlaw of motion, Acceleration is produced when a force acts on a mass. The greater the mass is, the grater the acceleration is needed to move forward. This law basically states that a force applied to the objects changes its velocity overtime in the direction of the force that is applied, the acceleration is directly proportional to the force, as an example, if pushing on an object, causing it to accelerate, and then you push, the same object three times harder, the acceleration will be three times greater and the acceleration is inversely proportional to the mass of an object, if you push equally on two objects, and one of the objects has five times more mass than the other, it will accelerate at one fifth of the object.
SUV’s have the greater mass than the car. So SUV’s need more force than light car to move forward in the direction the force is applied, we can say that SUV’s need more force to act than a car, for example driving an SUV and light car at the same velocity, the force needed for car would be less than the SUV and the car would run faster than a suv as it need less force than an SUV. SUV requires more fuel than a normal car. A Car could run faster than an SUV and it even requires less fuel. Therefore, the more mass the object has, it requires more force to...

Bernoulli’s Principle and Newton’sLaws of Motion
Bernoulli’s Principle
In fluid dynamics, Bernoulli’s principles states that an increase in the speed of the fluid corresponds to a decrease in pressure of the same fluid. Similarly, the decrease in pressure corresponds to a loss in the potential energy of the fluid. The principle is applicable to various types of fluids, which leads to Bernoulli’s equation. There are different types of Bernoulli’s equation depending on the nature of fluid in use. The principle is valid for most compressible and incompressible fluids at low Mach numbers (less than 0.3). For this principle, fluid particles are only subject to pressure and its own weight.
The principle of conservation of energy comes handy in deriving the Bernoulli’s principle. This law of conservation of energy holds that as long as a system is isolated from external factors/interference, the total amount of energy inside the system remains constant despite the energy transformation that also takes place. Therefore, the total sum of mechanical energy for a steady flow of fluid remains the same at all points in a streamline (University of Leeds, 2008). At a constant sum of kinetic and potential energy, an increase in the velocity of the fluid occurs when...
