Potential energy that depends on height is called

• kinetic energy

• elastic potential energy

• mechanical energy

• gravitational potential energy

The ability to do work is called

• energy

• conversion

• friction

• velocity

The total potential and kinetic energy of the particles in an object is called

• chemical energy

• thermal energy

• electrical energy

• mechanical energy

Unlike kinetic energy, potential energy is

• not measurable

• stored

• conserved

• energy of motion

A compressed spring has elastic potential energy.

• True

• False

A pole-vaulter first converts kinetic energy into

• elastic potential energy

• thermal energy

• mechanical energy

• chemical energy

The scientist who suggested that energy can be created under certain conditions was

• Einstein

• Pascal

• Newton

• Wright

The type of energy stored by fossil fuels such as coal is

• kinetic energy

• chemical potential energy

• mechanical energy

What type of conversion takes place when natural gas is used to heat water?

• chemical energy into thermal energy

• electromagnetic energy into chemical energy

• thermal energy into mechanical energy

The law of conservation of energy states that when one form of energy is converted into another

• energy is created in the process

• no energy is destroyed in the process

• energy is destroyed in the process

• some amount of energy cannot be accounted for
