Diagram 1 shows a mango falling from a tree. Which graph shows the acceleration, a, of the mango against time, t?

Which of the following has the smallest inertia?

A 1.8 kg rabbit Image for option A

B 850 g spanner Image for option B

Diagram 2 shows two boys launching a water rocket. The physics principle applied is

A concept of inertia B equilibrium of forces C principle of conservation of energy D principle of conservation of momentum

**[Bonus]** (Bending the legs only reduces the impulsive force (II). The impulse stays the same and the time in the air does not change, so no option is fully correct. Any answer is accepted.) Diagram 3 shows an athlete bending his legs when landing in a long jump event. Why does the athlete need to bend his legs? I To reduce the impulse II To reduce the impulsive force III To increase the time in the air IV To get maximum distance

A I and II B I and IV C II and III D III and IV

Graph 1 shows the relationship between gravitational force and mass for objects near the Earth's surface. The gradient of the graph represents

A Acceleration due to gravity B Universal gravitational constant C Object weight D Object momentum

Diagram 4 shows a planet of mass m moving in a circular orbit of radius r around the Sun of mass M. The planet takes an orbital period T to complete one revolution. Which of the following shows the correct relationship between T and m, M, r?

A T ∝ m² B T ∝ Mm C T ∝ r³ D T² ∝ r³

Diagram 5 shows the launch of a rocket into space. What is the minimum velocity required by the rocket to be launched into outer space? [Given that M = 5.97 × 10²⁴ kg, G = 6.67 × 10⁻¹¹ N m² kg⁻² and R = 6.37 × 10⁶ m]

A 2.03 × 10³ m s⁻¹ B 1.12 × 10⁴ m s⁻¹ C 2.44 × 10⁴ m s⁻¹ D 1.12 × 10⁵ m s⁻¹

What is the concept used in measuring the temperature of coffee using a thermometer?

A Thermal convection B Specific heat capacity C Specific latent heat D Thermal equilibrium

A substance is heated at a steady rate. It changes from a solid to a liquid, and then to a gas. Graph 2 shows how its temperature changes with time. Which section of the process involves the specific latent heat of vaporisation?
