Front

Scalar quantity + examples

Back

a quantity which does not depend on direction and only has the magnitude.

Examples include temperature, pressure, length, area, volume, distance and speed.

Front

Vector quantity + examples

Back

a quantity which depends on direction, which includes both magnitude and direction.

Examples include force, weight, displacement, velocity and acceleration.

Front

Distance

Measured in?

Back

a scalar quantity and is the total length of a path travelled. Common units are cm, m, and km.

Front

Displacement

Measured in?

Back

a vector quantity and is the straight-line distance between two points including the direction.

Measured with distance + direction e.g 4m East

Front

Magnitude

Back

refers to the size or amount of something without considering its direction.

Front

What is the distance and displacement? (to 2dp)

Back

Distance: 1km

Displacement: 316.22m NE/NNE

Front

Speed

Measured in?

Equation?

Back

a scalar quantity and is a measure of the time taken to travel a certain distance.

It is measured in distance per time e.g m/s or km/hr

Speed = distance/time

Front

Instantaneous speed

Back

the speed at any specific moment, like the reading on a car's speedometer

Front

Velocity

Measured in?

Equation?

Back

a vector quantity and is a measure of the time taken to achieve a certain displacement, including the direction of motion.

It is measured in speed + direction e.g 4m/s East

Velocity = displacement/time

Front

If the person travels from A to D, passing through B and C, covering a total distance of 11 m in 10 seconds, calculate the speed and velocity

Back

Speed: 1.1m/s (11/10)

velocity: 0.5m/s East
