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 a ball held at a height.

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 mechanical energy?

Back

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

How does energy transform in a roller coaster?

Back

In a roller coaster, potential energy is highest at the top of the track and transforms into kinetic energy as it descends.

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

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

At which point in a roller coaster is kinetic energy greatest?

Back

Kinetic energy is greatest at the lowest point of the roller coaster.

Front

What is an example of energy transformation in everyday life?

Back

An example is a light bulb transforming electrical energy into light and heat energy.

Front

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

Back

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