Types of Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is the energy that has the potential to be converted into kinetic energy.

How does mass affect potential energy?

Back

Potential energy is directly proportional to mass. If two objects are at the same height, the object with greater mass will have more potential energy.

What form of energy do water molecules have due to their random motion?

Back

Water molecules have thermal energy due to their random motion.

Front

What are some sources of heat energy?

Back

Sources of heat energy include burning wood, the Sun, and electricity.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass and speed of the object.

How is gravitational potential energy calculated?

Back

Gravitational potential energy is calculated using the formula: PE = mgh, where PE is potential energy, m is mass, g is the acceleration due to gravity, and h is height.

What is the relationship between kinetic energy and speed?

Back

Kinetic energy is proportional to the square of the speed of an object. If the speed doubles, the kinetic energy increases by a factor of four.
