Vectors And Scalars Flashcards
(14 cards)
1
Q
Scalar
A
Scalar quantities have only magnitude (size)
2
Q
Vectors
A
Vector quantities have magnitude (size) and direction
3
Q
Speed
A
How fast things are travelling
4
Q
Velocity
A
The speed in a certain direction
5
Q
Acceleration
A
A change in velocity
6
Q
Displacement
A
The distance from start to finish in a straight line and has a direction
7
Q
A=V-U
T
A
Acceleration = (velocity - initial or staring velocity)/time for velocity to change
8
Q
Which of these has direction Vector.... Scalar..... Speed...... Velocity.....
A
Vector has a direction
Scalar doesn’t have a direction
Speed has no direction
Velocity doesn’t have a direction
9
Q
D = S x T T = D / S S = D / T
A
Distance = speed x time Time = distance / speed Speed = distance / time
