• 4 Joules

What happens to gravitational potential energy when an object is dropped?

• It increases

• It converts into kinetic energy

• It remains constant

• It is destroyed

What is the standard value of gravity used in GCSE calculations?

• 9.8 m/s²

• 10 m/s²

• 11 m/s²

• 9.5 m/s²

How do you calculate gravitational potential energy?

• 1/2 x mass x velocity squared

• force x distance

In the example, what is the velocity of a ball dropped from 3 meters with a mass of 2 kg?

• 20 m/s

• 10 m/s

• 12.5 m/s

What is the relationship between gravitational potential energy and kinetic energy when an object falls?

• Kinetic energy is always greater

• They are equal at the point of impact

• Potential energy is always greater

• They are unrelated

What is the benefit of practicing exam questions on energy topics?

• They are always different

• They help memorize equations

• They follow similar patterns

• They are not useful

What is the formula for calculating velocity from kinetic energy?

• velocity = kinetic energy / mass

• velocity = square root of (2 x kinetic energy / mass)

• velocity = mass / kinetic energy

• velocity = mass x gravity
