Diagram 1 shows the difference in diameter of the Earth. All of the following statements about gravity on the Earth are true **except**

A gravitational acceleration at the Equator is 9.79 m s⁻² B the distance from the Equator to the centre of the Earth is longer than the distance from the pole to the centre of the Earth C the value of the Earth gravitational acceleration, g changes from one place to another D the value of gravitational acceleration, g at the Equator is greater than at the poles

3

The force acting per unit mass refers to

A weight B gravitational force C gravitational field strength D atmospheric pressure

4

Diagram 2 shows a Formula One racing car. The car uses materials with low density in its construction. This is because

A the acceleration increases as mass decreases. B a small mass produces a large force. C a large force produces a large inertia. D a composite material with low mass reduces costs.

5

A 'follow through' action with a constant force on a stationary object can change all of the following **except**

A initial momentum B final velocity C impulse D time of contact

6

A radar imaging satellite orbits around the Earth at a height of 525 km. What is the value of gravitational acceleration at that position? [Given, $G = 6.67 \times 10^{-11}$ N m² kg⁻², $R = 6.37 \times 10^{6}$ m, $M = 5.97 \times 10^{24}$ kg]

A 9.81 m s⁻² B 9.50 m s⁻² C 8.15 m s⁻² D 8.37 m s⁻²

7

Diagram 3 shows an astronaut floating on the Moon. > "When the astronauts landed on the Moon in 1969, they wore space suits and carried packs of heavy equipment. On the Moon, astronauts would weigh six times less than they do on Earth." Which statement explains the situation correctly?

A The mass of astronaut is smaller on the Moon B The mass of astronaut's suit is less on the Moon C The strength of the gravitational field on the Moon is higher D The Moon's gravitational pulling force is smaller

8

Which statement is **correct** about Kepler's Third Law?

A All planets move in elliptical orbits with the Sun at one focus B The line connecting the planet to the Sun will cover the same area in the same time interval as the planet moves in its orbit. C The square of a planet's orbital period is directly proportional to the cube of its orbital radius. D For a body in circular motion, there is a force acting on it that is always towards the centre of the circle.

9

Diagram 4 shows a cup of hot coffee. What will happen when the coffee and the cup are in thermal equilibrium?

A The temperature of the cup is increasing B The temperature of the coffee is decreasing C There is no net heat flow from the coffee to the cup D There is a net heat flow from the coffee to the cup

10

The latent heat of fusion for water is heat absorbed by

A 1 kg of ice during melting without changes in temperature B 1 m³ of ice during melting without changes in temperature C 1 kg of water to increase the temperature by 1 °C D 1 m³ of water to increase the temperature by 1 °C
