Physics Flashcards
what is the equation for average speed
average speed= distance moved over time taken
what is the equation for acceleration
acceleration= change in velocity over time taken
What is the difference between velocity and distance time graphs
Velocity-time graph shows how quickly something is moving and distance-time graph shows how far away something is
is distance a scalar
yes
what is a scalar
a quantity that has only size, the direction isnt specified
what is a vector
a quantity that has size and direction
exampls of vectors
weight, force,acceleration and velocity
examples of scalars
mass,time,speed
what is a gradient
a measure of how steep a line is
what does the gradient of a distance time graph give you
the speed
what is distance x time = to
speed
what is velocity measured in
m/s
what is acceleration measured in
m/s squared
how do you find the acceleration from a velocity time graph
height / base
