Why are Newton’s Laws of motion important?

Newton's Laws of Motion are significant because they are the foundation of movement efficiency and quality of movement- one of the main components of movement science. Movement efficiency is the study of the motion of everyday objectives and the forces that affect them.

All modern physical theories are specified in inertial reference frames and must conserve momentum. One of the most fundamental properties of nature are momentum conservation(in which we would call movement efficiency).

Familiarity with these concepts has set the way to understand more accurate and complicated physics theories, and in turn help you "move" to the next level. Whether you are looking to jump higher or even just walk faster.

How does Newton’s Law's of Motion affect you?

Newton's law are very important because they tie into almost everything we see in everyday life together. These tell us exactly how things move or sit still, how everything around us move and work together harmoniously. Newton's laws control how water flows, cars move and even your current quality of movement.

We can relate with them by following daily life examples

As we shake up the bottle of sauce! When you shake that bottle, you bring the bottom down, then suddenly you stop. Sauce will come out of the bottle because of inertia.

For a car to move, there must be friction between the wheels and the ground. The wheels exerts force on the ground because they are spinning, and the ground exerts a reaction force on the wheels. It is this force which pushes the car forward.

Hit the ball on the wall. There are two forces, your force with which ball thrown and the other is force of wall that is equal and opposite on the fist. Hence, the harder you hit the wall with ball, the more force is exerted on the ball by the wall; this is why ball bounce more.

What is Newton’s First, Second and Third Law's of Motion?

Newton’s First Law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by an outside force.

Newton’s Second Lawstates that the acceleration of an object is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. For a body whose mass m is constant, it will be written in the form

F = ma

where F (force) and a (acceleration) are both  vector quantities.

Newton's Third Law states that when two bodies interact, they apply force on each other that are equal in magnitude and opposite in direction.
