1.2 Kinematics Flashcards
1
Q
What is the equation for mean speed?
A
total distance / total time
2
Q
What is displacement?
A
The distance from starting point
3
Q
What is the equation for mean velocity?
A
mean velocity= total displacement / total time taken
4
Q
What is the equation for mean acceleration?
A
Mean acceleration = change in velocity / time taken
5
Q
How do you interpret a displacement time graph?
A
Gradient = velocity
Straight line = constant
Horizontal line = stationary
Curve = accelerating
6
Q
How do you interpret a velocity time graph?
A
Gradient = acceleration
Straight line = constant
Area under = displacement
Horizontal line = velocity
Curve - increasing acceleration
7
Q
How do you interpret a speed time graph?
A
Gradient - acceleration
Straight line = constant
Area under = distance
Curve = increase acceleration
