forces - scalar and vectors Flashcards
1
Q
examples of scalar quantities
A
mass, temperature, speed, energy, distance and time
2
Q
what do scalar quantities only have?
A
magnitude (size)
3
Q
what do scalar quantities not have?
A
a direction
4
Q
why does distance give no idea of direction?
A
because it is a scalar quantity
5
Q
examples of vector quantities
A
displacement, weight, force, velocity, acceleration, momentum
6
Q
what do vectors have?
A
both magnitude and direction
7
Q
what is displacement?
A
a distance in a specific direction
8
Q
what do we have state in displacement?
A
magnitude (size) and direction (North, east, south, west)
9
Q
what do we represent vectors with?
A
an arrow
10
Q
what does the length of arrow on a vector represent? what does the direction of the arrow represent?
A
the magnitude of vector
direction if vector
