Answer
The correct answer is B centripetal force, which is the force acting towards the center of the circular path, ensuring that the object maintains its circular motion.
Step 2
b(i) Draw an arrow on Figure 8 to show the direction of the force that keeps the object moving in a circular path.

Answer
A single arrow should be drawn pointing towards the center of the circular path, indicating that the centripetal force is directed inward.
Step 3
b(ii) Explain why it is not moving with constant velocity.

Answer
Although the object in Figure 8 may be moving at a constant speed, it is not moving with constant velocity because the direction of its motion is continuously changing. Velocity is a vector quantity that includes both speed and direction; hence, a change in direction at constant speed results in a change in velocity.
