Chapter 4.3, Problem 28PP

To determine

To identify: The forces acting on the bowling ball.

The forces applied by the ball on another object.

The objects on which forces are exerted.

Explanation of Solution

Introduction:

Gravitational force is a type of force which attracts two objects having mass. The gravitational force is an attractive force. Every object in the universe is pulling other object in it.

When a person lifts the ball, then he applies the force on ball in upward direction through his hand. Gravitational force will also act on the ball in downward direction.

The forces acting on the ball are gravitational force by earth and force applied by the hand.

The free body diagram is shown as,

  

Where, $F_G$ = gravitational force applied by earth

  $F$ = force applied by the person to lift the ball

Now, according to Newton’s third law, the ball will also apply the force on the hand and gravitational force on earth.

The forces are exerted on hand,ball and earth.
