Identify the action-reaction paris in the following situations:
a) a person takes a step
b) a snowball hits someone in the back
c) a footbal player catches a ball
d) a leaf falls to the ground
HELP
a) the Earth rotates the other way.
b) the person hit is moved.
c) the ball stops, and the catcher moves slightly (maybe an extra force on his foot moving the Earth slightly)
d) the Ground moves.
Certainly! To identify the action-reaction pairs in each situation, it's important to remember Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. Let's analyze each situation:
a) When a person takes a step:
The action in this situation is the person pushing their foot against the ground. The reaction is the ground pushing back with an equal force on the person's foot.
b) When a snowball hits someone in the back:
The action here is the snowball being thrown towards the person's back. The reaction is the force exerted by the snowball hitting the person's back. Additionally, there is a smaller reaction of the person's body pushing back against the snowball, causing it to deform or flatten upon impact.
c) When a football player catches a ball:
The action in this scenario is the football player's hands making contact with the ball, exerting a force to stop its motion. The reaction is the ball pushing back against the football player's hands. This reaction force allows the football player to feel the impact or weight of the ball in their hands.
d) When a leaf falls to the ground:
In this case, the action would be the gravitational force pulling the leaf towards the ground. The reaction, according to Newton's third law, is the leaf pushing up against the gravitational force. However, it's important to note that this reaction force is much smaller than the gravitational force since the leaf falls to the ground.
Identifying action-reaction pairs helps us understand how forces interact in different situations, and observing these pairs is crucial in understanding the principles of Newton's third law of motion.
