Home Challenge Lab 2- The force of Gravity
Topics covered in this lab:
The force of gravity
Newton’s Laws
One of the topics we have discussed is acceleration, meaning that the velocity of the object under study was changing. What causes something to accelerate? In this lab you will investigate the forces that affect the motion of objects.
Gravity Materials: <!--[endif]-->Something to toss (Please choose an object that will not break)
Toss an object straight up into the air and catch it as it falls back down. Carefully watch the objects vertical position as a function of time. Repeat your toss enough times that you are sure that you understand the motion of the object.
In order to answer the following questions, imagine that you were able to measure the distance of the object above your hands, the velocity of the object, and the acceleration of the object, all as a function of time. You may want to reference the power point lecture of the diagrams in your text to help answer these questions. Please give detailed answers in complete sentences.
What is the velocity of the object at the very top of its path?
Is the velocity of the object changing during the entire flight or just at certain times?
Explain.
What is the acceleration of the object at the very top of its path?
Does the acceleration of the object change while it is in flight?no
List all of the forces that are acting on the object while it is in flight.
You may want to refer to your text for the following:
Using the first grid provided on the following page, make a sketch of what you think the distance (above your hands) versus time graph would look like for the object.
Using the second grid provided on the following page make a sketch of what you think the velocity versus time graph would look like for the object.
Using the third grid provided on the following page make a sketch of what you think the acceleration versus time graph would look like for the object.

Newton’s First Law of Motion explains that objects in a state of uniform motion tends to remain in rest unless an external force is applied to it. Galileo’s concept of inertia is termed “Law of Inertia”. Law of Inertia, an object in motion will continue in the same motion unless acted by an outside force. Aircraft in flight is an example of First Law of Motion, four forces on an aircraft; lift, weight, thrust, and a drag. Consider the motion of an aircraft at constant altitude, we can neglect the lift and weight, a cruising aircraft at constant speed and the thrust balances the drag of the aircraft. This is the first part sited in Newton’s First Law; there is no net force on the airplane and it travels at a constant velocity in a straight line.…

For our experiment we look at how weight, size and shape of an object traveling through the air effects the acceleration of that object. Because the force of air resistance depends on whether laminar or turbulent flow is being experienced, we would expect to find accelerations that depended on not only weight but also on shape and size.…

Acceleration of an implement while in flight is constant and always -9.8 meters/second squared or 32 ft/s2 (feet per second squared); the act of gravity on the implement. Therefore, generally all objects fall to the earth at the same rate of acceleration, no matter how much they weigh. The force of gravity is always acting vertically; there is no horizontal deceleration in the absence of aerodynamic forces. Acceleration is the same regardless of the weight of the implement. Therefore, the vertical velocity of a projectile decreases by 9.8 m/s every second.…

Newton’s first law states “objects at rest will stay at rest unless an outside force acts on it and an object in motion will continue to stay in motion at constant speed in a straight line unless an outside force acts on it.” This means exactly what it says. If a ball is kicked it’ll go in a straight line until it hits a wall or someone stops it. If a ball is on the ground not moving it will stay not moving unless someone kicks it or something moves it. For my demo I went on the soccer field and got my soccer ball and kicked it. It went flying until it hit the fence. Then when I let the ball stay there, it didn’t move until I went to go get it. To me explaining an object in motion isn’t easier to explain but I love a challenge, it makes me work my brain.…

How does a cart change its motion when you push and pull on it? You might think that the harder you push on a cart, the faster it goes. Is the cart’s velocity related to the force you apply? Or does the force just change the velocity? Also, what does the mass of the cart have to do with how the motion changes? We know that it takes a much harder push to get a heavy cart moving than a lighter one.…

Physics is defined as the study of matter and energy as well as their interactions (Lombardi, 2001). Although physics is more theoretical based, countless solutions are discovered through observation/experimentation (Physics.org, ?) and many seemingly intricate things in nature can be understood in terms of relatively straightforward mathematical relationships. These mathematical relationships are a recurring concept in the fields of Kinematics and Dynamics which focuses on ways in which objects/matter move whilst evaluating behaviours like displacement, acceleration and velocity (Wise Geek, 03-13).…
