Answer
The correct answer is B centripetal force. This force acts towards the center of the circular path, ensuring the object continues to move around the circle.
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 circle as this indicates the direction of the centripetal force acting on the object.
Step 3
b)(ii) The object in Figure 8 is moving at constant speed. Explain why it is not moving with constant velocity.

Answer
Though the object's speed is constant, its velocity is not constant due to its changing direction as it moves along the circular path. Velocity is a vector quantity, which means it takes into account both speed and direction. Since the direction of the object is continuously changing, the velocity is also changing, even if the speed remains constant.
