Change in position
________________
Change in time
What is acceleration
What is it a measure of
What is the equation
What quantity is it
Change in velocity over time
Measure of how something is speeding up or slowing down
Velocity
____________
Time
It is a vector quantity
What is negative acceleration
Slowing down in the POSITIVE DIRECTION
OR
Speeding up in the NEGATIVE DIRECTION
What is average velocity
What is the equation
Velocity over some defined intervals
Change in Displacement
_____________
Change in Time
What is instantaneous velocity
Velocity at a specific time and space point
If a slope is positive what is the acceleration
What about the opposite
Positive
Negative
How do you work out the displacement from a Velocity-Time graph
Area under the rectangle for CONSTANT VELOCITY
OR
Area under the triangle for CHANGING VELOCITY
How do you work out the acceleration on a Velocity-Time graph
Slope of the curve
What are the 3 different linear kinematics graphs
Position-Time Graph
Velocity-Time Graph
Acceleration-Time graph
