Energy and Motion

Front

Kinetic energy is an energy of ____________ and potential energy is an energy of ________.

Back

Kinetic energy is an energy of motion and potential energy is an energy of position.

Front

Conservation of energy states that energy cannot be ________ or ________, but can be altered from one form to another.

Back

Conservation of energy states that energy cannot be created or destroyed.

Front

What is the formula to calculate Potential Energy (PE)?

Back

PE = mass (kg) × gravity (9.8 m/s²) × height (m)

Front

What is the formula to calculate Kinetic Energy (KE)?

Back

KE = 0.5 × mass (kg) × velocity² (m/s)²

Front

If an object has a mass of 10 kg and is moving at a speed of 5 m/s, what is its Kinetic Energy?

Back

KE = 0.5 × 10 kg × (5 m/s)² = 125 Joules.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

Front

What is the relationship between mass and energy in the context of motion?

Back

The greater the mass of an object and the faster it moves, the more kinetic energy it has.

Front

What happens to the potential energy of an object as it falls?

Back

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

Front

What is gravitational potential energy?

Back

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

Front

How does energy transformation occur in a roller coaster?

Back

In a roller coaster, potential energy is converted to kinetic energy as it descends.
