What is the formula for finding speed and velocity?
v= change in distance/displacement
————————————————-
change in time
What does a horizontal line represent on a displacement/time graph?
The object is at rest.
What does a diagonal line represent on a displacement/time graph?
The object is travelling at a constant speed.
What is acceleration?
Any change in the velocity of an object during a time interval.
What is the formula for finding acceleration?
a= change in velocity

change in time
A curved line on a displacement/time graph represents ________.
accelerated motion.
A horizontal line on a velocity/time graph says what about the acceleration?
There is no acceleration (speed is constant).
A diagonal line on a velocity/time graph means the acceleration is either ________ or _________.
Positive and constant or negative and constant.
The slope on a dt graph represents __________.
The speed.
The slope on a vt graph represents _________.
The acceleration.
The area under the curve on a vt graph represents ________.
The displacement.
The slope of an at graph represents _________.
The jolt (rate of change of the acceleration).
The area under the curve on an at graph represents ___________.
The velocity.
