kg x m/s2
what is inertia ?
An object at rest will stay at arrest and an object in motion will stay in motion and constant velocity unless acted upon by an unbalanced force.
who was Isaac newton ?

newtons third law states that for every action in nature there is ?
an equal and opposite reaction.
f=ma what does m mean ?
mass
The more mass the object has the more net force has to be used to move it. This has to do with witch of newtons laws?
newtons second law

Two masses are hung are connected by a light cord and hung from a frictionless pulley of negligible mass. Mass m1 =3.00kg, and mass m2 =2.00kg. When the two masses are released from rest, the resulting acceleration of the two masses is approximately?
a =2m/s2

A block of mass m is pushed across a rough surface by an applied force F, on an angle. The block experiences a friction force fin the opposite direction. What is the coefficient of friction between the block and the surface ?
f/F sin0-mg
In newtons second law, he defines a force to be ?
equal to the change in momentum (mass times velocity) per change in time.
what is the law of force and acceleration ?
force equals mass times acceleration (F=MA)
newtons law can be illustrated by identifying the pairs of forces involved (ex: blocks being supported by a spring). Witch law is this ?
newtons third law

three laws of motion in the "principia Mathematica philosophiae nuturalis"
An object moves in a straight line according to the equation x=2t3- 3t2- 6t , where x is in meters and t is in seconds. At what time is the net force acting on the object = 0 ?
t = 0.5s
newtons second law states that the acceleration of an object is ?
proportional to the force acting on it.
what is the equation for newtons second and third law ?

Newtons laws of motion deal with ?
everything to do with motion, forces, gravity, speed, or acceleration.
what was one of newtons most famous quotes ?
I have seen further than others, it is by standing upon the shoulders of giants.
I can calculate the motion of heavenly bodies, but not the madness of people.
To every action there is always opposed an equal reaction.
