# Newton’s Laws of Motion Smore

## Newton's 1st Law of motion

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

A object can't move unless another object uses force against it.

Inertia is the resistance of any physical object to any change in its state of motion including changes to its speed and direction or the state of rest. It is the tendency of objects to keep moving in a straight line at constant velocity.

Newton's Law Of Inertia

## Newton's second law of motion

The behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables, the net force acting upon the object and the mass of the object.

The steeper a ramp is, the more acceleration a object has.

Some examples are an object going down a ramp, an object going up a ramp, and object being pushed, an object being puled, and an object being thrown.

F=MxA

Acceleration is the increase in speed of an object.

In football, if you're a lineman, you have to push the opposing players to protect your Quarterback. While you're pushing the opposing player back you're applying a certain amount of newtons to do so. So in other words, you're forcing them back and making them accelerate.

## Newton's 3rd law of motion

For every action, there is an equal and opposite reaction.

If you push a object, the object basically pushes you back. Due to Newton's 3rd law of motion.

So say I step off a boat onto a dock, the boat is going to have a equal-opposite force. So it's going to either push away or shake when me or anyone steps off onto he dock. Due to Newton's 3rd law of motion.
