Gravity (GCSE Physics)

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

Which of the following correctly distinguishes mass from weight?

If you double the height through which a mass is lifted, what happens to the change in its gravitational potential energy (assuming constant mass and g)?

A ball rolls off a horizontal table and lands 1.5 m from the table base. If the table height is doubled, neglecting air resistance, the horizontal distance it lands will be:

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

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

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

A ball of mass m is thrown downward with initial speed v0 from height h. Which expression gives its speed at ground (ignore air resistance)?

A ball is thrown vertically upward from ground level with speed 14 m/s. Ignoring air resistance and using g = 9.8 N/kg, what is the maximum height reached (approx)?

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?
