What is acceleration?
is the rate of change of velocity
What is the equation of average acceleration when velocity changes over time?
units m/s2
Is acceleration a scalar or vector?
It is a vector because it has a magnitude and direction
What equation do you use when finding final position when the knowns are starting, positon, average velocity, and time
How do you find average velocity when acceleration is constant and you know initial and final velocity?
What happens when an object accelerates in the same direction as its velocity?
The object speeds up because acceleration adds to the velocity each time
What happens when an object accelerates in the opposite direction as its velocity?
The amount of acceleration subtracts from the velocity
What is deceleration?
It is when an object slows down or brakes
What equation do you use when you have to calculate for final velocity and acceleration and time are known

What equation do you use when finding final position but yours knowns are acceleration and time, initial position, and initial velocity
What equation do you use when finding velocity or position when time is not given?
What are the units?
