Resource summary

Question Answer
Force A push or a pull
Mass The amount of matter in an object
Weight the force applied to an object due to the gravitational attraction of a large mass like the Earth
The Normal Reaction Force A force that acts perpendicular to a surface as a result of an object applying a force to the surface
Friction A force that resists the relative motion or tendency of such motion between 2 bodies or substances in contact
Air resistance/Drag A force that opposes the relative motion of an object through a fluid
Net Force The vector sum of the forces acting on an object
Newtons 1st Law An object will remain at rest and a moving object will continue with the same velocity unless an unbalanced external force acts on it
Inertia The tendency of an object to resist a change in its motion. The mass of an object is a measure of its Inertia
Newtons 2nd Law The acceleration of an object will be directly proportional to the net force acting and inversely proportional to the mass of the object. The acceleration will also be in the direction of the force
Newtons 3rd Law If object A applies a force to object B, then object B will apply an equal magnitude force in the opposite direction on object A for the same duration
