Forces and Motion
What is Acceleration?
A change in velocity is called acceleration.
What is the Equation for Acceleration?
Acceleration = Change
in Velocity ÷ Time.
This equation is written as
a = (v-u) ÷ t
a = acceleration
v = final velocity (the one it ended up with)
u = initial velocity (the one it started with)
t = time
This equation is important!
What are the Units of Acceleration?
units of acceleration are m/s2
called "metres per second squared".
What is Negative Acceleration?
object gets faster, it will have a positive acceleration.
If an object gets slower, it will have a negative acceleration
(this is sometimes called "deceleration"
but the term "negative acceleration" is preferred).
