AB
The change in position, divided by the time during which the change occurredVelocity
The rate at which the velocity of an object changesAcceleration
The slope of a position time graph of an objectAverage Speed
Have both magnitude and directionVector Quantity
Quantities, such as temperature and distance, that are just numbers without any directionScalar Quantity
Projections of the component vectorsComponents
Objects show through the air that have independent vertical and horizontal motions and, after receiving and initial thrust, travel through the air only under the force of gravityProjectiles
The force that opposes a sliding motionFriction
A push or pull on an objectForce
the ability of a body to resist acceleration by a net forceInertia
An object at rest will remain at restNewton's First Law
The acceleration of an object is proportional to the net force and inversely proportional to the massNewton's Second Law
For every action there is a reactionNewton's Third Law
The amount of particles/matter in an objectMass
MassXGravityWeight
The vector sum of all forces on an objectNet Force
The perpendicular contact force exerted by a surface on another objectNormal Force
Unit for forceNewton
A on BAction Force
The exerted by a machine (B on A)Reaction Force
