Newtons Laws of Physics Newtons first Law of Physics An object in motion tends to stay in motion in a staight line.

The man, whom is projected forward after hitting the brick wall, is a prime example of Newton's first law of motion. The man's body was moving alonge with the car; when the car hits the wall the man's body tends to continue motion in the same direction.

Newton's 2nd Law!

The force of an object equals that of the mass of the object mutiplied by the accelerationof the object.

Or in other words the formula F=ma

For example if an object with a mass of 100kg is accelerating at 4m/s2 the force that the object exerted is 400N.

Newton's 3rd Law

A force is always an interaction betwween two material objects.

The airplane exerts a Force on the glidder causing it to accelerate. The glider in turn exerts a force on the airplane. There are, of course, additional forces present such as the propeller force and air drag on both planes

For example: my truck is out of gas so I am going to push my truck to the gas station. But because of my stupididity I put roller blades on because I can go faster on roller blades. and when I exert a force on the van it exerts a force on me.
