Question
An object starts from rest. It means that _____.
- Its initial velocity is zero
- Its final velocity is zero
- Its acceleration is zero
- Its displacement is zero
Hint:
It's initial velocity is zero
The correct answer is: Its initial velocity is zero
When an object starts from rest it means that it's initial velocity is zero.
Rest implies that the body was stationary with respect to the ground. Any body which doesn't move has zero velocity, since it doesn't covers any distance. Thus, any body starting from rest has initial velocity= zero.
