Resource summary
Motion
key terms
SPEED
is distance travelled per second
VELOCITY
is displacement travelled per second
it needs a direction
VECTOR
has magnitude (size) and direction
EG. velocity, acceleration, displacement
SCALAR
has a magnitude only
EG. speed, distance, height, mass, time
ACCELERATION
is the rate of change in velocity
Equations
SPEED = distance / time
VELOCITY = displacement / time
ACCELERATION = change in velocity / change in time
DISTANCE-TIME graphs
SPEED and GRADIENT are the same
GRADIENT = change in y / change in x
work out speed
VELOCITY - TIME graphs
work out acceleration
ACCELERATION and GRADIENT are the same
GRADIENT = change in y / change in x
= change in velocity / change in time
= acceleration
You can also work out the distance travelled
area = speed x time = distance
its the area under the graph of the section you want to find out
