. Choose the wrong statement

A: 1 kg wt = 9.8 N

B: Momentum is a vector quantity.

C: Force is always conserved.

D: Momentum is conserved in the absence of an external force.

Best Answer

Explanation:

In Any 1 kg object the gravitational force act is equal to (1kg9.8m/s2)=9.8N .
The momentum is a product of mass and acceleration and as it has a direction also so it is a vector quantity.
Force is not conservative in all way example friction because this force is not depend upon the path.
Momentum is always conserved when any external force is not acted.

Final answer:

The option ( c) is correct.
