Transfer of Energy

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object that is used to do work.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or arrangement.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

How does energy transfer occur?

Back

Energy transfer occurs when energy moves from one object or system to another, often through work or heat.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of energy transformation?

Back

An example of energy transformation is a hydroelectric dam converting potential energy of water into electrical energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy held by an object because of its height above the ground.

Front

What factors affect potential energy?

Back

Potential energy is affected by the mass of the object and its height above a reference point.

Front

What is an example of kinetic energy?

Back

A moving car has kinetic energy due to its motion.

Front

What is the relationship between potential and kinetic energy in a pendulum?

Back

In a pendulum, potential energy is highest at the highest point, while kinetic energy is highest at the lowest point.
