Acceleration Flashcards
1
Q
Definition of Acceleration
A
It is the rate at which the velocity of an object changes over time
2
Q
Acceleration Formula
A
Velocity / TIme
3
Q
Avg Acceleration Formula (ā)
A
v2 - v1 where v1, v2 are velocity
———– = ā at time t1 and t2
t2 - t1 respectively
4
Q
How to tell in graph which is positive is negative or zero acceleration
A
Inward Curve -> Positive a
Outward Curve -> Negative a
Straight Line (sloped, flat) -> Zero a
NOTE -
Area under/above the curve represents area at a given time interval
5
Q
What cannot occur in a acceleration - velocity graph
A
Values for either a or v cannot change in a instant, changes are always continuous
