A
The only have magnitude (size)
2
Q
What are some examples of scalars
A
speed, distance, mass, time, temperature, charge
3
Q
What are vectors
A
Have both magnitude (size) AND direction
4
Q
What are some examples of vectors
A
acceleration, velocity, displacement, force (don’t get confused if they name a force such as weight because this will still be a vector) and momentum
5
