An object in a space probe above the Earth weighs 3.5 N. The gravitational field strength at the height of the space probe is 7.0 N / kg. The gravitational field strength on the Earth’s surface is 9.8 N / kg.

A space rocket travels to the Moon. The acceleration of free fall is greater on the Earth than it is on the Moon. How do the mass and weight of the space rocket on the Moon compare with their values on the Earth?

Which statement about mass or weight is not correct? (A) Masses can be compared using a balance. (B) Mass is a force. (C) Weights can be compared using a balance. (D) Weight is a force.

Which statement about a falling object accelerating close to the Earth’s surface is correct?

The gravitational field strength on the Moon is smaller than that on the Earth. A scientist examines a rock which has been brought back from the Moon.

A sphere P, made of steel, has a weight of 10 N on Earth. Another sphere Q, also made of steel, has a weight of 10 N on Mars. The gravitational field strength on Earth is greater than the gravitational field strength on Mars.

An object falls towards the surface of the Earth. The object is falling at its terminal velocity. Which statement is correct?

A light ball is held at rest at the top of a tall cliff. It is released and falls through the air, eventually reaching its terminal velocity. Which row describes the behaviour of the ball as it descends?

Which row shows the mass and the weight of an object near the Earth’s surface?

A rock falls off a cliff onto a beach. The effect of air resistance on the rock is negligible. Which row describes the acceleration and speed of the rock as it falls?
