Sir Isaac Newton
Biography
Isaac Newton was born in 1642 at the woolsthrope near Grantham, Lincolonshine, England.
Newtons first law
Deals with inertia of objects. Continue with it's motion unless acted upon by another force.
1st law world problem
passengers move forward when the driver breaks the bus. Passengers before the brake have same velocity with bus.
a force that is going in a negative direction will make a negative velocity
Newtons second law
Newtons second law uses force,mass and acceleration

Faith Alford, Joshua Willis
1'st period
He worked on his mother's farm at the age 14.
. The key point here is that if there is no net force
Isaac returned to school in 1660 to get ready for entrance to Trinity college at cambride university in 1661.
Lucasian Professor of Mathematics in 1669.
If that veloci
ty i
s zero, then the object remains at rest
will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
When the parachutist releases his parachute the frictional drag is suddenly increased to be greater that his weight the parachute moves upward.
the acceleration is directly proportional to the force because of the position the object
F = ma is the equation for newtons second law
The Equation mean to applied acceleration of the object to find the answer from the equation.
2st world problems
One problem is bumper cars.When you collide to another bumper car you move forward because of the collision
When you push a ball the velocity go to 0 to how much you push it.
Newtons third law
The third law means that for every force there is the same opposite force.
forces may change during the two objects pushes together.
you use energy to push the two objects together they pushing back on you
Also force to push the object that give you the same .
the quote on the website says if you push on it.It pushes on you
law 3 world problems
When you move boxes by pushing on it it pushes back on you

When you walk on the grass the ground pushes upward on you.
