Energy Transformations

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as potential energy to kinetic energy.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as an object at the top of a hill.

Front

What is kinetic energy?

Back

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

Front

How does potential energy change as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

What happens to energy in a pendulum?

Back

In a pendulum, potential energy is highest at the top of the swing, and kinetic energy is highest at the lowest point.

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 in a roller coaster?

Back

In a roller coaster, potential energy is converted to kinetic energy as the coaster descends from a height.

Front

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

Back

As a falling object descends, its potential energy decreases while its kinetic energy increases.

Front

What is an example of an object with both potential and kinetic energy?

Back

A moving car on a hill has both potential energy (due to its height) and kinetic energy (due to its motion).
