What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic, potential, thermal, and chemical energy.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state. For example, a raised object has gravitational potential energy.

Front

What is elastic energy?

Back

Elastic energy is the potential energy stored in an object when it is compressed or stretched, such as in a spring or a drawn bow.

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 happens to energy when a bow is drawn back?

Back

When a bow is drawn back, elastic energy is stored in the bow. When released, this energy is converted to kinetic energy of the arrow.

Front

What happens to a rollercoaster's energy as it descends?

Back

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

Front

How does a solar panel work?

Back

A solar panel converts light energy from the sun into electrical energy through the photovoltaic effect.

Front

What energy transformation occurs in a flashlight?

Back

In a flashlight, chemical energy from the battery is transformed into light energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its height above the ground, calculated as mass times gravity times height.
