Worked Solution & Example Answer:The force that keeps an object moving in a circular path is known as the A balancing force B centripetal force C reaction force D resistance force (b) Figure 11 shows an object moving in a circular path - Edexcel - GCSE Physics - Question 7 - 2019 - Paper 1
Step 1
Draw an arrow on Figure 11 to show the direction of the force that keeps the object moving in a circular path.
Answer
To demonstrate the direction of the centripetal force that keeps the object moving in a circular path, draw an arrow pointing towards the center of the circular path from the object in Figure 11.
Step 2
The object in Figure 11 is moving at constant speed. Explain why it is not moving with constant velocity.
Answer
The object is moving in a circular path, which means its direction is continuously changing. Even though the speed of the object remains constant, velocity is a vector quantity that depends on both speed and direction. Since the direction is changing, the velocity of the object is also changing, which means it is not moving with constant velocity.
