Objects with mass are acted on by this noncontact force:
Magnetism
Inertia
Gravity
Friction
For every action there is an equal and opposite reaction
Newton's third law
Newton's first law
Newton's second Law
Law of Momentum
An object at rest will stay at rest. An object in motion will stay in motion unless acted on by an unbalanced force.
Newtons 1st Law
Newtons 2nd Law
Newtons 3rd Law
Law of Conservation of Momentum
Acceleration depends on the net force and the mass of an object
Newton's 1st Law
Newton's 2nd Law
Newton's 3rd Law
Law of Conservation of Momentum
Total movement of objects stay the same unless unbalanced forces act on the group of objects
Newton's 1st Law
Newton's 2nd Law
Newton's 3rd Law

Velocity:
The rate at which distance changes over time
speed in a certain direction
change in velocity over time
amount of force used over a distance
Acceleration:
The rate at which distance changes over time
speed in a certain direction
change in velocity over time
amount of force used over a distance
The formula for Newton's Second Law is
M = fa
S = d/t
F=ma
W = fd
Law of Force and Acceleration or Newton's 2nd Law states
objects in motion will stay in motion; objects at rest will stay at rest
the acceleration of an object depends on the net force applied and the mass of the object
the total movement of a group of objects stays the same unless there are unbalanced forces acting on the group of objects
with every action there is an equal and opposite reaction
