Question

Amy throws a softball through the air. What are the different forces acting on the ball while it’s in the air?

The softball experiences [___] force as a result of Amy’s throw. As the ball moves, it experiences [___] from the air it passes through. It also experiences a downward pull because of [____].

First space:
An applied, An attractive, A normal.

Second Space:
Attraction, Drag, A push.

Third Space:
Drag, Gravity, Normal Force.

Answer 1

An applied force is a force that is applied to an object by a person or another object.
An attractive force is a force of an attraction (where object are attracted by each other). Gravitation is an example of attractive force.
Normal force is the component, perpendicular to the surface (surface being a plane) of contact.
The softball experiences an applied force as a result of Amy’s throw. As the ball moves, it experiences attractive force from the air it passes through. It also experiences a downward pull because of the normal force.
Solution A.

Answer 2

An applied force, drag force and gravitational force.

Explanation:

When Amy throws a softball through the air, there is some force that acts on it. The forces that are experienced by the ball in the air as follows :

The softball experiences an applied force as a result of Amy’s throw. As the ball moves, it experiences a drag from the air it passes through. It also experiences a downward pull because of gravity.

The applied force is defined as the force applied by the person who is throwing the ball.

Drag is equivalent to the frictional force that is applied in the opposite direction.

The gravitational force always acts in downward direction.
