Gravity (GCSE Physics)

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

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:

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)?

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

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 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 satellite in low Earth orbit stays in orbit because:

Which of the following correctly distinguishes mass from weight?

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:

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?
