Gravity (GCSE Physics)

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

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?

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

A 5.0 kg mass is raised vertically by 4.0 m. How much work is done against gravity? (g = 9.8 N/kg)

A 70 kg astronaut stands on the Moon where the gravitational field strength is 1.6 N/kg. What is the astronaut’s weight on the Moon?

A soccer ball is kicked straight up with speed 20 m/s. Neglecting air resistance, how long will it take to return to its starting height? (Use g = 10 N/kg for quick estimate.)

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

Which of the following correctly distinguishes mass from weight?

Which situation gives the largest gravitational field strength at a point near the surface?
