Kinetic and Potential Energy

The total mechanical energy of a given system is changeable?

• True

• False

Conservation of mechanical energy refers to the total sum of the potential energy and kinetic energy of a system that remains the same as long as the only forces acting are conservative forces.

• True

• False

In the law of conservation of energy, the decrease in potential energy is the same as the increase in kinetic energy.

• True

• False

A thrown baseball has kinetic energy

• True

• False

Potential energy is energy in motion.

• True

• False

The faster an object moves, the smaller kinetic energy it has.

• True

• False

When you are holding a book, energy is stored between the book and Earth; this type of energy is called potential energy

• True

• False

Mechanical energy is the total amount of potential energy and total amount of kinetic energy.

• True

• False

The wind blowing through your hair is an example of potential energy

• True

• False

The "Law of Conservation of Mechanical Energy" states that the total mechanical energy in a system remains constant as long as the only forces acting are conservative forces.

• True

• False
