Newton's first law states that objects do not change their velocity unless acted upon by an outside force. When throwing a ball the ball initially accelerates from the force
provided by your arm and then begins to slow down.
What force(s) are responsible for the deceleration of the ball?

What should the power status of a circuit be when measuring resistance with an ohmmeter?
