Acceleration and velocity time graphs Flashcards
1
Q
What is acceleration?
A
How quickly the velocity is changing.
Change in velocity can be a change in speed or a change in direction or both.
2
Q
Formula for acceleration?
A
Acceleration = change in velocity divided by time taken.
3
Q
What does v mean
A
Final veloctity.
4
Q
What does u mean
A
Initial velocity.
5
Q
Unit for acceleration.
A
m/s squared.
6
Q
Gradient =
A
acceleration.
7
Q
Flat sections=
A
steady speed.
8
Q
Steeper the graph=
A
Greater the acceleration or deceleration.
9
Q
What is the area under the graph?
A
Is equal to the distance travelled in that time interval.
10
Q
The distance travelled at any time inetrvak is equal to what?
A
The area under the graph
