Question

Which of the following situations are possible and give example of each:- (a) An object moving in a certain direction having negative acceleration. (b) Force is applied on the object but work done is zero​

Answer 1

Explanation:

Heya!!

Here is your answer!!

1.When acceleration is negative it means velocity of body is decreasing with respect to time.

2.Workdone is the force. displacement. Even if force is applied and if displacement is zero then the workdone of the object will be zero.

Hope it helps u!!

Answer 2

Answer:

SoluTion :-

1. A car who has Initial velocity greater than final velocity
2. When displacement is 0

Know More :-

• SI unit of Acceleration is m/s²
• SI unit of velocity is m/s
• Displacement is the shortest distance travelled by body.
