Gravity (GCSE Physics)

Which equation gives the change in gravitational potential energy when an object of mass m is lifted through height h in a uniform gravitational field g?

Which of the following correctly distinguishes mass from weight?

Which quantity remains the same for an object lifted slowly from Earth’s surface to a higher location: its mass, weight, gravitational potential energy, or all three?

Which of these factors will reduce your weight reading on a bathroom scale?

An apple falls from a tree; just before hitting the ground most of its initial gravitational potential energy has been converted into:

A spacecraft is in deep space far from other masses. Which is true about its weight and mass?

A stone is dropped from rest in a vacuum close to Earth. Which graph best shows its velocity-time behaviour (qualitative)?

A person of mass 60 kg climbs a 12 m high ladder. What increase in their gravitational potential energy occurs? (g = 9.8 N/kg)

Two balls of the same size but different masses are dropped from the same height in a vacuum. Which will hit the ground first?
