![]() Time graph represents the instantaneous velocity of the cart at the time of 0.8 seconds. The slope determined in part III for the Displacement vs. This problem could be avoided if we smooth wheels were used. Therefore, the points on the VT graph do not connect to form a straight line because at some points, the acceleration is different. The uneven friction caused by possible bumps on the track may result in un-uniform acceleration. Uneven friction was another source of error. To resolve this situation, we can line up the cart at a certain mark to make the starting point of each trial consistent. It could have been off by 1 millimeter or more and the starting point could have been different each trial. ![]() Given just a cart, a ramp with a ruler at the edge of it, "photogates," string and a device to calculate the time, it was hypothesized that acceleration can be found by determining the slope of the Velocity-Time graph and the displacement can be found by determining the area under the line or curve of the graph.Ī source of error from the experiment was that it was difficult to line up the card at the 20 centimeter mark. Instantaneous velocity is the velocity of an object at a given instant, especially when the object is accelerating. Time graph, the instantaneous velocity was determined at different distances. Lastly, acceleration is how fast the velocity is changing or rate at which velocity is changing. Velocity is how fast an object moves and in what direction it is moving. Displacement is how far an object travels or the total path an object moves on, including its direction. The objective of the lab was to obtain the displacement and the acceleration of a moving body from its Velocity vs. Any one of these values can be determined from a graph that involves time, displacement, and velocity. A moving body always has displacement, velocity, and acceleration. Kinematics is the branch of mechanics dealing with motion of an object without discussing force and mass.
