A
Change in velocity over time
3
Q
What’s uniform acceleration
A
Constant acceleration
4
Q
Acceleration =
A
Change in velocity /time
5

A
Speed ❌time
6
Q
What was Newton’s 1 law
A
That an object with no net force acting on it moves with constant velocity in a straight line
7
Q
What’s Newton’s 2 law
A
The acceleration of an object is directly proportional to the net force on the object
