Speed, Velocity, Distance and Displacement

Identify what is happening between points A & B (hint: what type of graph is this?)

• the subject is accelerating

• the subject is travelling at a constant speed

• the subject is not moving

• the subject is travelling at a constant speed North East

Describe the difference between distance & displacement

• distance is a vector quantity and displacement is a scalar quantity

• distance is a scalar quantity and displacement is a vector quantity

• distance includes direction and displacement doesn't

• displacement only includes magnitude

Charlie travels 900m to get to school in the morning. Over the course of the day, he covers a distance of 650m (walking to class etc.). He then travels 900m to return home. Identify his total displacement (m).

• 0m

• 2450m

• 900m

• 1800m

Identify what velocity is a measurement of

• total distance travelled, divided by time taken

• total displacement travelled, divided by time

• total displacement travelled, divided by velocity

• total speed of an object, multiplied by time

Identify what speed is a measurement of:

• total distance travelled, divided by time

• total displacement travelled, divided by time

• total distance travelled, divided by speed

• total speed of an object, multiplied by time
