P9 Motion Flashcards
Einstien energy equation
E= M x C2
Energy = mass x speed of light squared
What is the value of the speed of light
300 000 000 m/s
Equation for speed
S= D/t
Speed = distance divided by time
Equation for distance
D= S x T
Distance= Speed x Time
Equation for time
T= D/S
Time = distance divided by speed
What is the acceleration of an object
A measure of how quickly the objects velocity changes
Equation for acceleration
a= V-U/t
Acceleration = final velocity - initial velocity divided by time
Equation for time taken
Time taken = change in speed divided by acceleration
How do you calculate the gradient
Change in y divided by the change in x
Equation for velocity
V=d/t
Velocity= distance divided by time
Equation for displacement
S= UT + (V-U)t/2
Displacement = start velocity x time + (final velocity - start velocity) time divided by 2
