  1. Total Mechanical Energy • The total mechanical energy of a system is defined to be the sum of: • The total potential energy of the system • The total kinetic energy of the system • The symbol used for total mechanical energy is E. The units of E are joules. • The total mechanical energy of a system can be negative if and only if the total potential energy is negative and has a greater magnitude than the total kinetic energy.

  2. Example A 50.0 gram tennis ball is at rest on the ground. The tennis ball is then thrown upward…

  3. A 50.0 gram tennis ball is thrown upward – when it is at a height of 0.75 meters above the ground… The change in gravitational potential energy of the tennis ball is: 0.75 m

  4. 1.35 m/s 0.75 m A 50.0 gram tennis ball is thrown upward – when it is at a height of 0.75 meters above the ground… When the ball reaches the height of 0.75 m, it is traveling at 1.35 m/s. The kinetic energy of the ball is:

  5. 1.35 m/s 0.75 m A 50.0 gram tennis ball is lifted to a height of 0.75 meters above the ground. When the ball reaches the height of 0.75 m, it is traveling at 1.35 m/s. What is the total mechanical energy of the system?
