8.2- Acceleration Flashcards
1
Q
define acceleration
A
the change of velocity per unit time
2
Q
define uniform acceleration
A
velocity changes at a constant rate
3
Q
What does the gradient on a velocity-time graph =
A
acceleration
4
Q
equation for accelration
A
a = (v-u) / t
5
Q
define non-uniform acceleration
A
velocity changes at a varying rate
6
Q
what type of graph will be produced on a speed-time graph for an object with non-uniform acceleration
A
a curve
- curve up = acceleration
- curve down = decleration
7
Q
what is Newton’s 2nd law of motion
A
acceleration is
proportional to the resultant force acting upon it
inversionally proportional to the mass of the object
F = ma
