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 converting to kinetic energy.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, such as height above the ground.

Front

How is mechanical energy defined?

Back

Mechanical energy is the sum of potential energy and kinetic energy in a system.

Front

What happens to potential energy as an object falls?

Back

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

Front

Where is potential energy highest in a roller coaster?

Back

Potential energy is highest at the highest point of the roller coaster.

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

How does energy change in a pendulum?

Back

In a pendulum, energy transforms between potential energy at the highest point and kinetic energy at the lowest point.

Front

What is an example of energy transformation in everyday life?

Back

An example is a battery converting chemical energy into electrical energy to power a device.

Front

What is the relationship between height and potential energy?

Back

The higher an object is, the more potential energy it has due to its position in a gravitational field.
