. 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.
- 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.
The option ( c) is correct.
