Choose the correct statements regarding momentum.
Statement 1: Momentum has both direction and magnitude.
Statement 2: SI unit of momentum is Kg m s-1 .
Statement 3: A balanced force can create a change in velocity.
Statement 4: An unbalanced force can create a change in velocity.
Statement 5: A balanced force can create a change in momentum.
Statement 6: An unbalanced force can create a change in momentum.
Momentum = m * v;
The momentum depends on both direction and magnitude.
The SI unit of p is Kg m s-1 .
Since an unbalanced force can bring a change in motion i.e. velocity; and p depends on velocity, p can be changed by the application of unbalanced force.
A balanced force cannot bring a change in the motion, thus balanced force cannot change momentum.
