Energy Transfer and Transformations

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a plate lifted into a cabinet has potential energy.

Front

How does energy change from potential to kinetic?

Back

When an object moves from a higher position to a lower position, its potential energy is converted into kinetic energy.

Front

What is energy transformation?

Back

Energy transformation occurs when energy changes from one form to another, such as potential energy changing to kinetic energy.

Front

Where is gravitational potential energy the highest on a roller coaster?

Back

Gravitational potential energy is highest at the highest point of the roller coaster, such as position W.

Front

What is the relationship between speed and kinetic energy?

Back

The relationship is direct; as speed increases, kinetic energy increases.

Front

What happens to energy during a fall?

Back

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

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

Front

What is energy transfer?

Back

Energy transfer is the movement of energy from one place to another, such as heat moving from a hot object to a cooler one.
