a ball is thrown through the air, but is still affected by gravity. what is the correct relationship of forces acting between the ball and the earth?
Answer
Explanation:
Step1: Recall Newton's third - law
According to Newton's third - law, for every action, there is an equal and opposite reaction. The Earth exerts a gravitational force (weight) on the ball downwards. The ball exerts an equal and opposite gravitational force on the Earth.
Step2: Identify the force direction
The force of the Earth on the ball is downwards (towards the center of the Earth), and the force of the ball on the Earth is upwards (opposite to the direction of the Earth's pull on the ball). The correct pair of arrows is the one with one arrow pointing down and one arrow pointing up.
Answer:
The middle set of arrows (one arrow pointing down and one arrow pointing up)
