Kinematics Flashcards
1
Q
Displacement from a to b
A
The shortest distance from a to b together with direction
2
Q
Mean speed
A
Mean speed = total distance/total time
3
Q
Mean velocity
A
Mean velocity = total displacement/total time
4
Q
Mean acceleration
A
Mean acceleration = change in velocity/time taken
5
Q
Instantaneous speed
A
The rate of change if distance
6
Q
Instantaneous velocity
A
The rate of change of displacement
7
Q
Instantaneous acceleration
A
The rate of change of velocity
8
Q
Acceleration due to gravity
A
The acceleration of a freely falling object (where gravity is the only force)
9
Q
Terminal velocity
A
The constant maximum velocity of an object when the resistive forces on it are equal and opposite to the accelerating force (often gravity)
