Energy Transformations

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or height. It has the potential to be converted into kinetic 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

How does height affect potential energy?

Back

The higher an object is positioned, the greater its potential energy. This is because potential energy is directly proportional to height.

Front

What happens to energy when a ball is dropped?

Back

As the ball falls, its potential energy decreases while its kinetic energy increases, demonstrating the transformation of energy.

Front

What is the formula for kinetic energy?

Back

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

Front

What is the formula for potential energy?

Back

The formula for potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object or system to another, often resulting in a change in energy form.

Front

What is an example of energy transformation?

Back

When a roller coaster climbs to the top of a hill, it has potential energy. As it descends, that potential energy transforms into kinetic energy.

Front

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

Back

In a bouncing ball, potential energy is highest at the peak of the bounce, while kinetic energy is highest just before it hits the ground.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object possesses due to its position in a gravitational field, typically related to its height.
