Question

5.
The direction of change in momentum will be
a) along the direction of final velocity
b) along the direction of applied force
c) along the direction which is perpendicular to applied force
d) along the direction opposite to direction of applied force​

Answer 1

Answer:

I think, b is correct answer.

Along the direction of force applied.

Explanation:

Hope it helps you.

Answer 2

The Main Answer is: b) along the direction of applied force

• According to Newton's Second Law of Motion, the force applied to an object is equal to the rate of change of its momentum.
• Therefore, $F = \frac{p_{f}-p_{i} }{t}$ , where $p_{f}$ and $p_{i}$ are the final and initial momentums respectively.
• In vector terminology, we can infer that the direction of the force vector is the same as that of the 'change in momentum' vector.

Additional Information

1. The momentum of an object is the product of its mass and instantaneous velocity.
2. Momentum is a vector quantity, and its symbol is 'p'.
3. ∴ p = mv
