Kinematics Flashcards
What are the different variables in suvat equations?
s = displacement u = initial velocity v = final velocity a = acceleration t = time
What are the 5 suvat equations?
v = u + at s = t x (u+v)/2 s = ut + 1/2 x at^2 v^2 = u^2 + 2as
What is the definition of displacement?
Distance from a particular point measured in a straight line
What is the definition of velocity and speed?
Velocity is the rate of change of displacement
Speed is magnitude of velocity
What is the average speed equation?
total distance traveled / total time taken
What is the average velocity equation?
total displacement / total time taken
What is acceleration?
Rate of change of velocity
What is the gradient of a displacement time graph?
Velocity
What is the gradient of a velocity-time graph?
Gradient is the acceleration
What is the area under a velocity-time graph?
Displacement
What is the gradient of a speed-time graph?
Magnitude of the acceleration
What is the area under a speed-time graph?
Distance travelled
What is the formula for the area of a trapezium?
Area = 1/2 x (a+b) x h a = length of one straight side b = length of other straight side h = perpendicular height of the trapezium
What is the area under the acceleration-time graph?
Velocity change during that time
In which direction does gravity act?
Vertically downwards
