If the line on a distance-versus-time graph and the line on a speed-versus-time graph are both straight lines going through the origin, can the two graphs be displaying the motion of the same object? Explain.

A ball with a mass of 0.50 kilograms is moving at a speed of 1.8 meters/second along the positive x-axis. It collides with another ball of the same mass travelling at a speed of 2.0 meters/second toward the positive y-axis.

Match the description to the proper category to differentiate reflection and refraction 1) speed of ray does not change 2) Ray bounces off a boundary 3) Direction found by law of reflection 4) Direction found by Snells Law 5) Speed of ray changes 6)

Two trains are traveling side-by-side along parallel, straight tracks at the same speed. In a time t, train A doubles its speed. In the same time train B increases its speed by a factor of 5.42.
