On a distance-time graph, what does a diaganol line represent?
A diaganol line represents constant speed on a distance-time graph
On a distance-time graph, what does a horizontal line represent?
A horizontal line represents being stationary on a distance-time graph
On a distance-time graph, what does a curved line represent?
A curved line represents acceleration/deceleration on a distance-time graph
What is displacement?
Displacement is the distance and direction
On a displacement-time graph, what does a diaganol line represent?
A diaganol line represents constant speed on a displacement-time graph
On a displacement-time graph, what does a horizontal line represent?
A horizontal line represents being stationary on a displacement-time graph
On a displacement-time graph, what does a curved line represent?

On a displacement-time graph, what is average speed?
Average speed = Total Distance/Total Time
On a displacement-time graph, what is average velocity?
Average velocity = Total displacement/Total Time
On a velocity-time graph, what does a horizontal line represent?

On a velocity-time graph, what does a diaganol line represent?
A diaganol line represents acceleration/deceleration on a velocity-time graph
On a velocity-time graph, what does a curved line represent?
A curved line represents a change in acceleration/deceleration in a velocity-time graph
On an acceleration-time graph, what does a horizontal line represent?
A horizontal line represents constant acceleration on an acceleration-time graph
On an acceleration-time graph, what does a curved line represent?
A curved line represents a change in acceleration/deceleration on an acceleration-time graph
On an acceleration-time graph, what does a diaganol line represent?

What does s represent in SUVATs?
s = displacement
What does v represent in SUVATs?
v = final velocity
What does u represent in SUVATs?
u = initial velocity
What does a represent in SUVATs?
a = acceleration
What does t represent in SUVATs?
t = time
v = u + at
final velocity = initial velocity + (acceleration*time)
s = 1/2 (u + v) t
displacement = 1/2 (initial velocity + final velocity) time
v^2 = u^2 + 2as
(final velocity)^2 = (initial velocity)^2 + (2accelerationdisplacement)
s = ut + 1/2at^2
displacement = (initial velocitytime) + (1/2acceleration*time^2)
s = at - 1/2at^2
displacement = (final velocitytime) - (1/2acceleration*time^2)
