MOTION (PART 1)

The quantity that describe how fast something is travelling.

• Newtons per kilogram (N/kg) or metres per second squared (m/s²)

• Speed or velocity

• Distance

• time

The standard unit of speed, velocity is?

• Newton (N)

• meter (m)

• meter per second (m/s)

• kilogram (kg)

The standard unit of distance is?

• gram (g)

• Newton (N)

• meter per second (m/s)

• meter

The equation linking average speed, distance moved and time taken

• average speed = distance moved ÷ time taken

• average speed = distance moved x time taken

• average speed = time taken ÷ distance moved

The quantity that describe rate of change of velocity is?

• speed

• distance moved

• time taken

• acceleration

The standard unit of acceleration.

• metres per second (m/s)

• metres per second squared (m/s²)

• Newton (N)

• metre (m)

The equation linking acceleration, change in velocity and time taken is?

• acceleration = time ÷ change in velocity

• Newtons per kilogram (N/kg) or metres per second squared (m/s²)

• acceleration = change in velocity ÷ time

• acceleration = change in velocity x time

The symbol equation linking acceleration, change in velocity and time taken.

• Newtons per kilogram (N/kg) or metres per second squared (m/s²)

• a = t ÷ (v - u)

• a = (v - u) x t

• a = (v - u) ÷ t

'v' in the equation a = (v - u) ÷ t stands for this.

• final velocity

• initial velocity

• time taken

• acceleration

'a' in the equation a = (v - u) ÷ t stands for this.

• final velocity

• initial velocity

• time taken

• acceleration
