Chapter 3.1, Problem 5R

To determine

Whether there will be forces acting on an object if the object is at rest and an unbalance force is acting on an object if it is moving.

Explanation of Solution

Introduction:

Force is a push or pull that can change the state or position of an object. The displacement is depends on the direction of forces applied.

When the forces are acting in the opposite direction but have identical values, they will produce no displacement.

When the speed or direction of the object’s motion is changing, there is a non-zero net force acting on it. So, there will be forces acting on an object if the object is at rest.

Conclusion:

Yes, there will be forces acting on an object if the object is at rest and an unbalance force will be acting on an object if it is moving.
