The area under a curve in a velocity versus time graph gives
displacement
Average acceleration formula
Average acceleration= change in velocity/change in time
Average speed formula
average speed= total distance/total time
Equation of motion (final velocity v, initial velocity u, acceleration a, time t)
v = u + at
Vector component in x-direction
vcosθ (Where velocity = v)
To find the resultant of vector quantities...
...you can combine the vector quantities by vector addition.
The gradient of a velocity-time graph=
Acceleration
Average acceleration formula (when given displacement)
Acceleration= change in displacement/time taken
Formula for force
Force = mass x acceleration F = ma
The gradient of a displacement-time graph=
Velocity
Velocity formula
Velocity=displacement/time
Equation of motion (Distance s, initial velocity u, final velocity v, time t)
s = [(u+v)/2] • t
Equation of motion (Distance s, initial velocity u, time t, acceleration a)
s = ut + 1/2 • a • t^2
Vector components
the vertical and horizontal vector that makes up the resultant vector
Equation of motion (Initial velocity u, final velocity v, acceleration a, distance s)
v^2 = u^2 + 2as
The area under a curve in an acceleration versus time graph gives
