Q1 Final Review

Front

What is a pure substance?

Back

A pure substance is a material that has a constant composition and consistent properties throughout. Examples include elements like gold and compounds like water.

What happens to kinetic and potential energy as a roller coaster travels from a high point to a low point?

Back

Kinetic energy decreases while potential energy increases as the roller coaster moves from position X to position Y.

Front

What is gravitational potential energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or arrangement. It can be converted into kinetic energy.

Front

How can you determine the kinetic energy of an object?

Back

You can determine the kinetic energy of an object by finding its mass and speed using the formula KE = 1/2 mv².

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and speed.

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position.

Front

What is an example of a pure substance?

Back

An example of a pure substance is distilled water, which contains only H2O molecules.

Front

What happens to energy during a roller coaster ride?

Back

Energy transforms between kinetic and potential forms as the roller coaster moves up and down.
