• both Kinetic and Potential

Why would a system have less energy than it originally started with?

• The energy was lost as heat.

• The energy was destroyed.

• More energy was created at the beginning than at the end.

• The temperature was too low to create heat.

Mechanical energy is defined as the sum of both the potential energy and the kinetic energy of an object. According to the law of conservation of energy, what happens to mechanical energy if the potential energy of an object decreases?

• Mechanical energy increases.

• Mechanical energy decreases.

• Mechanical energy increases then decreases.

• Mechanical energy remains unchanged.
