1.2 Kinematics Flashcards
Displacement
The straight line distance a particle travels in a given direction
Velocity
Rate of change of displacement
Speed
Distance travelled per unit time
Acceleration
Rate of change of velocity
Mean velocity
The average velocity measured over a significant amount of time
Mean speed
The average speed measured over a significant amount of time
The gradient at a given point of a displacement-time graph gives the value for …

t = time
u = initial velocity
v = final velocity
a = acceleration
x = displacement
v = … + at
