Vectors And Scalars Flashcards
Scalar
Scalar quantities have only magnitude (size)
Vectors
Vector quantities have magnitude (size) and direction
Speed
How fast things are travelling
Velocity
The speed in a certain direction
Acceleration
A change in velocity
Displacement
The distance from start to finish in a straight line and has a direction
A=V-U
T
Acceleration = (velocity - initial or staring velocity)/time for velocity to change
Which of these has direction Vector.... Scalar..... Speed...... Velocity.....
Vector has a direction
Scalar doesn’t have a direction
Speed has no direction
Velocity doesn’t have a direction
D = S x T T = D / S S = D / T
Distance = speed x time Time = distance / speed Speed = distance / time
Is speed a scalar or vector quantity
Scalar
Is velocity a scalar or vector quantity
Vector quantity
Name some examples of scalar quantities
Temperature Mass Energy Distance Speed Density
Magnitude
The size of a physical quantity
Name some examples of vector quantities
Force Weight Displacement Velocity Acceleration Momentum
