Pushing on a wall is an example of which law of motion?
A
First
B
Second
C
Third
D
Fourth
Explanation: 

Detailed explanation-1: -Newton’s third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.

Detailed explanation-2: -According to Newton’s third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.

Detailed explanation-3: -Examples of Newton’s third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.

Detailed explanation-4: -Newton’s Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass (object). Riding your bicycle is a good example of this law of motion at work. Your bicycle is the mass. Your leg muscles pushing pushing on the pedals of your bicycle is the force.

Detailed explanation-5: -Answer and Explanation: According to Newton’s third law, we see that when you push a wall with a force the same amount of reaction force is applied by the wall to you. The diagram shows the action and reaction forces F in the wall acting opposite to each other.
