When can we use suvat

When an object is in uniform acceleration

Define uniform acceleration

Where the acceleration of an object remains constant

Define distance (travelled by an object)

The distance travelled by an object (is a scalar quantity) describes the amount of ground the object has covered

Define displacement

The overall distance travelled from starting point (is a vector quantity)

Define speed

Describes the distance travelled per unit of time (is a scalar quantity)

Define velocity

The rate of change of displacement

Define acceleration

The rate of change of velocity

What does a Displacement-time graph show

Shows change in displacement over time

What does the gradient of a Displacement-time graph represent

The velocity

What does a Velocity-time graph show

Shows the change in velocity over time

What does the gradient of a Velocity-time graph represent

The acceleration

What does the area under the Velocity-time graph represent

The displacement
