Newton's 3 laws of motion

Question 1

First law

Answer 1

Newton’s first law of motion is that every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed on it. Inertia is the tendency of a thing to remained unchanged. In other words thing want to keep doing what they are already doing. Inertia can be thought of as lazy, it does not want to change.

Question 2

Second law

Answer 2

Newton’s second law of motion is the fact that acceleration of an object depends on the mass of the object and the amount of force applied to it.

In mathematical terms:
Force = Mass x Acceleration

Question 3

Third law

Answer 3

Newton’s third law is the fact that for every action there is an equal and opposite reaction. For example, a tennis ball that hits the ground causes a downward force, instantly the floor reacts by pushing the ball with the same force but in the opposite direction. In an example of a bicycle, the tires push the ground backwards and the ground pushes the tires forward with the same force.
