Question

the english physicist and mathematician sir isaac newton discovered three basic laws of motion. the first law says that objects at rest and objects in motion will remain at rest or in motion, unless they are acted upon by an “unbalanced force.” the second law says that when a force acts on a mass, acceleration is produced. the greater an objects mass is, the more force is needed to accelerate it.
newtons laws of motion have become known throughout the world, including his third law of motion. it reads: “for every action, there is an equal and opposite reaction.” a simpler way of saying this might be: “when you push an object, it pushes back.” for every force, in other words, there is a reaction force equal in size.
there are many ways to describe how the third law of motion works in the world of sports. one of the more interesting examples is the way that lebron james dunks a basketball.
in order for lebron james to score a slam-dunk, he must
3 read the following sentences from the passage:
“when lebron james jumps, he pushes down on the surface of the court. this is the action that newton mentions in his third law.”
based on this information, lebron james jumping is an example of which part of newtons third law?
a both the action and the equal and opposite reaction
b the equal and opposite reaction of an action
c the action which causes an equal and opposite reaction
d neither the action nor the equal and opposite reaction
4 the force created when the court pushes lebron james upwards is equal to which force?

Explanation:

The passage explicitly states that LeBron pushing down on the court (part of his jump) is the 'action' referenced in Newton's Third Law, which triggers an equal and opposite reaction. This matches option C.

Answer:

C. the action which causes an equal and opposite reaction
