Discussion - Lab Report Example However, the box does not move due to friction. How do the magnitudes of the forces between you and the box compare to each other? The magnitude of the force holding the box onto the surface is higher as compared to that applied to move the box. This explains the reason why the box remains on the surface and does not move. The force of friction is dependent on the total force that is pressing the two surfaces together. b. You switch to a box that has a mass that is half of your mass and try to push it across the floor, but it also does not move. How do the magnitudes of the forces between you and the box compare to each other? The magnitude of the force holding the box onto the surface is lower as compared to that applied to move the box. This implies that the resisting force (friction) is lower than the force that is applied to start motion and this causes the box to remain onto the surface without any motion towards any of the directions. For motion to occur, the two forces must have equal magnitudes. c. You are able to place the box that has a mass half of your own onto a platform with wheels and you are able to push the box across the floor. How do the magnitudes of the forces between you and the box compare to each other? The magnitude of the force holding the box onto the surface is equal to the force of friction. The wheels reduce the resisting force (friction) between the floor and the box and hence the box is able to slide across the floor. Once the two forces have equal magnitudes, the box is able to slide across the floor. 3. You apply a 2 Newton force to a 0.5 kilogram cart on a track and measure the acceleration of the cart with a motion detector. The acceleration is measured to be equal to 3.5 meters/sec2. Calculate the frictional force. In which direction compared to the applied force is it directed? Newton’s third law states that for every force that is applied, there is a resultant reaction force that is
