The rate at which speed changes is called

ACCELERATION


Another word for rate of change is

RATE


What are the two rates of motion?

SPEED and ACCELERATION


What is the following an example of? "Your speed goes from 20 mi/h to 60 mi/h."

CHANGE in SPEED or VELOCITY ("Delta" V)


The triangle symbol (delta) means

CHANGE IN


The symbol for acceleration is

a


The symbol for change in velocity

"delta" v


The equation for acceleration is

CHANGE IN VELOCITY / TIME


The equation for change in velocity is

FINAL VELOCITY  INITIAL VELOCITY


The units for change in velocity are

m/s


The units for acceleration are

m/s/s or m/s^2


What is the following an example of? "Your speed goes from 20 mi/h to 60 mi/h in 5 seconds."

ACCELERATION


The amount of speed increase or decrease compared to how long the speed takes to change is

ACCELERATION


The slope on a speed vs. time graph is equal to

ACCELERATION


The yaxis on an acceleration graph is

SPEED or VELOCITY


The xaxis on an acceleration graph is

TIME


Another word for negative acceleration is

DECELERATION


Positive acceleration means...

SPEEDING UP


Negative acceleration means...

SLOWING DOWN


No acceleration means...

CONSTANT SPEED


The acceleration of somthing dropped straight down is called

FREEFALL


Other than changing speed, what else can cause acceleration?

CHANGING DIRECTION


The steeper the hill, the faster you accelerate due to the effect of

GRAVITY
