Question

Q Which of the following can sometime be zero for a moving body?
O average velocity
O displacement
O both
O none​

Answer 1

Answer:

Both Average velocity and displacement

Explanation:

★ Displacement can be defined as the shortest path length taken by an object

★ Average velocity is the total displacement covered by an object in a particular time interval.

★ The displacement and average velocity of a moving body becomes zero when the body returns back to its original position.

Not clear?

Let's understand this by an example:

A •-----------------• B

Suppose body travelled from point A to point B and returned back to point A.

So, Displacement = 0

We know that:

Average velocity = Displacement ÷ Time

→ Average velocity = 0 ÷ Time

→ Average velocity = 0

∴ Both average velocity and displacement can be zero for a moving body.
