vertical motion are independent of each other; that is‚ neither motion affects the other. Acceleration Since there is no acceleration in the horizontal direction velocity in horizontal direction is constant which is equal to ucosα. The vertical motion of the projectile is the motion of a particle during its free fall. Here the acceleration is constant‚ equal to g.[1] The components of the acceleration: a_x = 0 ‚ a_y = -g . Velocity The horizontal component of the velocity remains unchanged

law 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

and Gravity Define mass‚ weight‚ force‚ and acceleration. Mass – A measure of the total amount of material in a body‚ defined either by the inertial properties of the body or by its gravitational influence on other bodies. It is proportional to‚ but not the same as‚ its mass Force – A quantitative description of the interaction between two physical bodies‚ such as an object and its environment. Force is proportional to acceleration. Acceleration – A vector quantity that is defined as the rate

come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration‚ force‚ and percent error one will be able to distinguish and evaluate the relationship between the two laws. II. Procedures of experiment: All groups had

inaccurate. To improve this‚ the car could have been rolled down the ramp three times and the average of those measurements could have been used for a more accurate result to measure the change in position. However‚ if only the increase in velocity and acceleration are calculated‚ another set of dots that were marked on the ticker tape could have been used as well for trials. A more precise measuring tool could have been used so the measurements would have been much more precise. Other random errors could

In the book‚ Thank You for Being Late: An Optimists Guide for Thriving in the Age of Accelerations‚ the author‚ Thomas Friedman‚ explains throughout his book that there are three social forces that are accelerating and buffeting individuals and communities. Based on his text‚ these three social forces are known as: technology‚ globalization

Cart on a Ramp Argument Essay The experiment can be used to determine the acceleration due to gravity accurately when the slope of the ramp is extrapolated to 90 degrees. Experimentally‚ the acceleration due to gravity is valid because when the ramp is set to a 90 degree angle‚ it essentially has no slope‚ so objects that are set at a 90 degree angle experience free-fall which is 9.8 m/s2. Using this knowledge‚ during the experiment if the ramp is set at a higher slope‚ it is essentially approaching

AIM: Finding the gravitational field strength by using a simple harmonic motion of a spring and slotted masses. INTRODUCTION: When a mass suspended from a spring is displaced‚ due to the acceleration‚ kg s-2‚ from its equilibrium and released it will oscillate up and down with a kind of motion called simple harmonic motion‚ shm. The period (T)‚ time taken to measure for one complete oscillation‚ of this motion is: m/kg =
