Question

A. List any two differences between distance and displacement..

b. When is an object said to have uniform circular motion.

Answer 1

Distance and displacement are both physical quantities used to measure the motion of an object, but they have some key differences. Distance is the total length of the path traveled by an object, while displacement is the change in position from the initial point to the final point.

Step-by-step explanation:

Distance and displacement are both physical quantities used to measure the motion of an object, but they have some key differences.

1. Definition: Distance is the total length of the path traveled by an object, while displacement is the change in position from the initial point to the final point.
2. Direction: Distance is a scalar quantity and has no direction attached to it, while displacement is a vector quantity and includes both magnitude and direction.

For example, if you walk 10 meters north and then 10 meters south, your distance traveled would be 20 meters, but your displacement would be zero because you've returned to your initial position.
