First Law of Motion
An object at rest stays at rest and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.
Second Law of Motion
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).
Third Law of Motion
For every action, there is an equal and opposite reaction.
Inertia
The tendency of an object to resist changes in its state of motion.
Net Force
The vector sum of all the forces acting on an object.
Acceleration
The rate of change of velocity of an object with respect to time.
Mass vs Weight
Mass is a measure of the amount of matter in an object; weight is the force of gravity acting on that mass.
Friction
A force that opposes the motion of an object, acting parallel to the surfaces in contact.
Gravitational Force
The attractive force between two masses, proportional to their masses and inversely proportional to the square of the distance between their centers.
Force
A push or pull on an object, which can cause it to accelerate.
