What is newton laws

Newton's laws of motion, named after Sir Isaac Newton, (1642-1727) a British mathematician, physicist, astronomer and natural philosopher, are three physical laws that, laid the foundation for classical mechanics. Newton's third law of motion: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body. Newton's first law of motion: A body continues in a state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed upon it. Newton's second law of motion: The change of motion of a body is proportional to the motive force impressed and is made in the direction of the straight line in which that force is impressed.

Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces.

First law : Every body persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed upon it.

Second law : The change of motion is proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed.

Third law : To every action there is always opposed an equal reaction: or, the mutual actions of two bodies upon each other are always equal and directed to contrary parts.

The best way to illustrate the concept of force is by using a simple example: Let's say you have a ball and you want to launch it as far as you can. You find a suitable place, stand about 10 feet away from the ball, and give it a good kick. The ball moves away from you, but it doesn't go very far. You try again and again, but the ball seems to glide along the grass rather than sail through the air. Eventually, you can see the ball moving farther and farther away. You are able to launch it farther and farther away. Why does this happen? The answer is: force. By putting your foot behind the ball and giving it a good kick, you put force into the ball. The ball comes away from your foot with more energy than it had before you hit it. The energy is transferred from your foot to the ball and causes the ball to accelerate. That acceleration causes the ball to move faster and faster, until finally it leaves the ground.

This is a simple force calculator I created which you can use to see the calculations of an object that experiences acceleration due to a force. You can change the mass and acceleration of the object, and see the force vector and the force vector magnitude change. You can also change the direction of the acceleration with the 'acceleration vector' box.
