7. Kinetic Energy and Work Kinetic Energy
• Kinetic energy is proportional to the mass. If a bowling ball and a ping pong ball have the same velocity, the bowling ball has much larger kinetic energy. • Kinetic energy is always positive. • unit : Joule (J) = kg ⋅m 2 /s2 Example: If we drop a 3-kg ball from a height of h = 10 m, the velocity when the ball hits the ground is given by:
