A ball thrown by Ginger is moving upward through the air. Which force diagram represents the forces on the ball? You may neglect the effects of air resistance.

a) only down force
b) only up force
c) both forces
d) both forces (but down is larger/longer).

I am unsure if it is a) or d). The fact that it is moving upward through the air is throwing me off. Does the fact that it's moving "upwards" create a normal force? Or is gravity just affecting the ball at this point?
Please help? Thanks

two forces down: gravity, and air friction. Many will ignore air friction, so go with a)

Ok, thank you for your input:) I'll get back about the answer.

If possible, could you please look at the other question I posted?

Yes, that answer along with the other question I posted were both correct! Thanks again:)

To determine the forces acting on a ball thrown by Ginger moving upward through the air, we need to consider the different forces involved.

The primary force acting on the ball is gravity, which always acts downward towards the center of the Earth. This force remains present regardless of the ball's direction of motion. Therefore, gravity is a force that needs to be included in the force diagram.

Additionally, we need to consider the normal force, which is the force exerted by a surface to support the weight of an object resting on it. In this case, since the ball is moving through the air and not in contact with any surface, there will be no normal force acting on it. Thus, we can exclude the normal force from the force diagram.

Considering these factors, the correct force diagram representing the forces acting on the ball would be option d) both forces (but down is larger/longer). This diagram would include both the downward force of gravity (to represent the ball's weight) and an upward force (to represent the ball's motion).

Note that while the ball is moving upward, it does not create a normal force as it is not in contact with any surface. Gravity is still acting on the ball, reducing its upward acceleration and eventually causing it to slow down and reverse direction.
