Vector Kinematics -- Position
In the applet to the right you will see a moving object and its motion diagram over a given time interval. (Think of it, for example, as a ball in the mouth of a dog, as viewed from above.) Your task is to understand the relationship between velocity, displacement, and the position of the ball at the beginning and end of its motion. The acceleration is constant in this motion, so the average velocity is just half the sum of the initial and final velocities. Click "?" for instructions.
