Kinetic Energy and Speed Relationships

The video tutorial explains how to graph the speed and kinetic energy of a ball with constant mass. It starts by plotting the first data point with a speed of 1 m/s and energy of 1 joule. Additional data points are plotted for speeds of 3, 4, and 6 m/s with corresponding energies. The graph is analyzed, showing a curve that indicates an exponential increase, rather than a straight line, demonstrating that the relationship is not proportional.

What remains constant when graphing the speed of the ball?

• The speed of the ball
