Question

A moving body changes its velocity when a net force acts on it. A body that is initially at rest moves when a net force acts on it. Using a recording timer, the spacing of the dots on the paper tape pulled by the cart shows clearly whether the cart moves with a constant speed or with an acceleration. The regularly spaced dots mean motion with a constant speed; the increasing spaces between dots indicate accelerated motion. A stopwatch can also be used to determined the time needed to travel a given distance. A shorter time of travel for the same distance means higher speed, longer time means lower speed. Objectives: 1. To define net force 2. To determine the net force acting on a body 3. To relate net force and the acceleration of a body 4. To apply Newton
