Gravity (GCSE Physics)

At height h above Earth’s surface, gravitational field strength g decreases slightly with increasing altitude. Which consequence is correct?

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

An object of mass 0.50 kg is attached to a light spring and is lowered slowly by 0.80 m. The gravitational field strength is 9.8 N/kg. How much energy is stored as gravitational potential energy?

Which statement about the Moon’s gravitational field is true compared with Earth’s?

A 2.0 kg object is raised vertically by 5.0 m near Earth (g = 9.8 N/kg). What is the increase in its gravitational potential energy?

Which of the following best explains why astronauts feel weightless in orbit?

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

Which factor does NOT affect the gravitational force between two objects?

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

A skydiver jumps from a plane and initially accelerates towards Earth. Later the skydiver reaches terminal velocity. Which statement about terminal velocity is correct?

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?
