Newton's Laws of Motion

Newton's First 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.
In the picture above the baseball player is about to throw the ball. After he lets go of the ball it would keep going with the same speed and direction if there were no such thing as gravity, wind, or unbalanced forces. Since there are unbalanced forces, the ball will sooner or later slow down and land on the ground due to gravity.

About Isaac Newton

Isaac Newton, was born in 1642 and died in 1727, he was a famous mathematician and physicist. He discovered the three laws of motion and other things such as the binomial theorem and was one of the creators of calculus. Overall he was a very influential person.

Newton's Second Law of Motion

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

It takes force to push this round box. The person would have to push more than the weight to start the acceleration of the box. And to keep it moving. The same idea goes along with a mother pushing a shopping cart full of groceries and the red man pushing the round box. It takes force to accelerate the speed of the object.
This picture shows the equation to calculate force. First you have to plug in the numbers for mass and acceleration and multiply them together to get the force of the object. Force is the amount of energy it takes to get something to move. Mass and acceleration are important to force because you have to know the time the object can accelerate and how big (or massy) it is. the more massy the object the longer it takes for the object to accelerate.

Newton's Third Law of Motion

when an object exerts a force on a second object, the second object exerts a force on the first object that is equal in strength and in the opposite direction
