Kinetic and Potential Energy Concepts

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and the square of its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It is often associated with gravitational energy when an object is elevated.

Front

How is potential energy converted to kinetic energy?

Back

As an object falls or moves downward, its potential energy decreases while its kinetic energy increases, demonstrating the conversion between the two forms of energy.

Front

What happens to energy during a pendulum swing?

Back

At the highest point of the swing, potential energy is at its maximum, and kinetic energy is at its minimum. At the lowest point, kinetic energy is at its maximum, and potential energy is at its minimum.

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 is an independent variable in an experiment?

Back

An independent variable is the factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is a dependent variable in an experiment?

Back

A dependent variable is the factor that is measured or observed in an experiment, which changes in response to the independent variable.

Front

What is friction and how does it affect energy?

Back

Friction is a force that opposes motion between two surfaces in contact. It can convert kinetic energy into thermal energy, causing energy loss.

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object or system to another, such as when a moving ball hits a stationary ball.

Front

What is an example of energy transformation?

Back

An example of energy transformation is a roller coaster: as it climbs, kinetic energy is transformed into potential energy, and as it descends, potential energy is converted back into kinetic energy.
