Unit 6 Test Corrections

Front

What type of energy do moving objects have?

Back

Kinetic energy

Front

At which point on a roller coaster is the potential energy the greatest?

Back

At the highest point of the roller coaster (Point A)

Front

At which point on a roller coaster is the kinetic energy the greatest?

Back

At the lowest point of the roller coaster (Point B)

Front

What is gravitational potential energy?

Back

The energy an object possesses due to its position in a gravitational field, calculated as weight times height.

Front

How do you calculate gravitational potential energy?

Back

Gravitational Potential Energy (GPE) = mass (kg) × gravitational acceleration (9.8 m/s²) × height (m)

Front

If Josh is 3m up a ladder and weighs 100N, and Mark is 2m up the ladder and weighs 150N, who has more gravitational potential energy?

Back

They have the same gravitational potential energy.

Front

What happens to kinetic energy when mass increases?

Back

Kinetic energy increases if velocity remains constant.

Front

What happens to kinetic energy when velocity increases?

Back

Kinetic energy increases if mass remains constant.

Front

What is the formula for kinetic energy?

Back

Kinetic Energy (KE) = 1/2 × mass (kg) × velocity² (m/s)²

Front

What is potential energy?

Back

The stored energy in an object due to its position or state.
