Scalars and Vectors Flashcards
Vector
a physical quantity that has both magnitude and direction
Scalar
a physical quantity that has only magnitude
Resultant Vector
a single vector that has the same effect of the original vectors acting together (Fnet)
Position
a point at which an object is located reference to a point / an origin.
Distance
the length of the path travelled
displacement
the change in position
speed
the rate of change of distance (V)
velocity
the rate of change of displacement (V)
acceleration
the rate of change of velocity (a)
Example Vectors
- displacement
- velocity
- weight
- acceleration
- force
Example Scalars
- distance
- speed
- mass
- time
- energy
Weight
the gravitational force that the Earth exerts on any object on or near its surface (or core) (W)
Normal
the force perpendicular to on object exerted by the surface it is in contact with (Fn)
Friction
the force of a surface that opposes the motion of an object, acting parallel to the surface the object is in contact with but in the opposite direction. (Ff)
acceleration
the rate of change of velocity
