Kinematics Flashcards
1
Q
Definition of speed
A
Distance traveled per unit time
2
Q
Speed equation
A
Speed=distance/time
3
Q
Define velocity
A
Change of distance in unit time in a specific direction
or
rate of change of displacement
4
Q
Velocity equation
A
Velocity=displacement/time
5
Q
Define acceleration
A
Rate of change of velocity
6
Q
Acceleration equation
A
Acceleration=change in velocity/time taken
7
Q
Gradient of a displacement time graph
A
Velocity
8
Q
Gradient of velocity time graph
A
Acceleration
9
Q
Area under a velocity time graph
A
Displacement
10
Q
Suvat equations
A
v=u+at
s=1/2(u+v)t
s=ut=1/2at^2
v^2=u^2+2as
