Chapter 3, Problem 42R

To determine

The correct term that is not a force among the given terms.

Answer to Problem 42R

Momentum is not force and the correct option is option (C).

Explanation of Solution

Introduction:

Force is a kind of push or pull that is responsible for the movement in block or body.

Force is vector quantity and its SI unit is ‘Newton (N)’. There are various kind of forces are hydrostatic force, friction force, weight, tension, air resistance, etc.

The momentum of object is evaluated by taking the product of object’s mass and its velocity. The SI unit of the momentum is $\text{kg}\cdot \text{m}/\text{s}$ .

The mathematical expression to calculate the momentum is,

  $p=mv$

Here,

• $m$ is object’s mass.
• $v$ is object’s velocity.

Conclusion:

Therefore, the momentum is not force.
