Conservation of Energy

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. For example, water held behind a dam has potential energy because of its height.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. For example, a moving car or a rolling ball has kinetic energy.

Front

How does height affect Potential Energy?

Back

The higher an object is, the more potential energy it has. For example, a roller coaster at the top of a hill has more potential energy than at the bottom.

Front

What happens to Potential Energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, demonstrating the conservation of energy.

Front

Can energy be created or destroyed?

Back

No, energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

What is the relationship between Kinetic and Potential Energy in a roller coaster?

Back

In a roller coaster, energy transforms between potential and kinetic energy as it moves up and down the track.

Front

Give an example of Kinetic Energy in everyday life.

Back

An example of kinetic energy is a student doing tricks with a yo-yo, as the yo-yo is in motion.

Front

What is an example of Potential Energy in nature?

Back

An example of potential energy in nature is a rock perched on a cliff, which has energy due to its height.

Front

How does energy conservation apply to skiing?

Back

When skiing down a mountain, potential energy is converted into kinetic energy, allowing the skier to gain speed.

Front

What is the formula for Kinetic Energy?

Back

The formula for kinetic energy is KE = 1/2 mv², where m is mass and v is velocity.
