1. identify each force acting on the ball and its interaction pair in the figure below.

Answer

Explanation:

Step1: Identify contact force

The hand exerts a contact - force on the ball. According to Newton's third law, the ball exerts an equal and opposite contact - force on the hand.

Step2: Identify gravitational force

The Earth exerts a gravitational force (weight) on the ball, pulling it downwards. The ball exerts an equal and opposite gravitational force on the Earth.

Answer:

  1. Contact force: Hand on ball and ball on hand.
  2. Gravitational force: Earth on ball and ball on Earth.
