Energy Review

Front

What is the definition of energy transfer?

Back

Energy transfer is the process of energy moving from one system or object to another, often resulting in a change in form or state.

Front

What are the two main types of energy?

Back

The two main types of energy are potential energy and kinetic energy.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, such as a rock sitting on a ledge.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and velocity.

Front

How is energy transferred from potential to kinetic energy?

Back

Energy is transferred from potential to kinetic energy when an object in a high position (potential energy) falls or moves, converting its stored energy into motion.

Front

What is an example of energy transfer from electrical to thermal?

Back

An example is a toaster, where electrical energy is converted into thermal energy to toast bread.

Front

What role does food play in energy for students?

Back

Food provides the chemical energy that students need to perform physical activities and maintain bodily functions.

Front

What happens during a collision between two moving objects?

Back

During a collision, energy is transferred from one object to another, resulting in a change in motion for both objects.

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 potential energy in everyday life?

Back

A stretched rubber band has potential energy due to its position and tension.
