Vectors + Scalars (speed + velocity)

What are scalars?

What are scalars?

Measurements that only have a size. Examples include distance speed, mass and energy. Eg speed, distance

What are vectors?

Measurements that have a size as well as a direction. We can represent vectors using arrows, the size of the arrow determines the size of the vectors and the arrow determines the direction. Eg velocity, displacement

What is speed?

How fast you’re travelling. It’s a scalar

What is velocity?

How fast you’re travelling in a direction. It’s a veector

What is distance?

how far you’ve travelled. It’s a scalar

What is displacement?

How far you’re from the start. It’s a vector

How do you calculate for an object moving at constant speed and distance travelling in a specific time?

average speed = distance travelled / time

V = s / t

How do you calculate velocity with displacement and time?

average velocity = displacement / time

V = x / t
