the law of inertia
another name for newtons first law
mass
the amount of inertia an object has depends on this
how can you use newtons second law to find force
kilograms
two ways to increase the acceleration of an object
by changing the force and to change the mass
newtons 3rd law of motion
states that if one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object
equal and opposite
the action and reaction forces in any situation will always be these
