Acceleration and velocity time graphs and distance time graphs

what is acceleration

the rate of change of velocity

what is the equation for acceleration if you're given the time

acceleration = change in veocity ( or final velocity - initial velocity )/time

what is the equation for velocity if you're given the distance

2as = v^2 - u^2

2 x acceleration x distance = finaly velocity^2 - initial velocity ^2

if an object is stationary what is its initial velocity

0

what is the unit for acceleration

m/s^2

what does it mean when the line is flat on a velocity time graph

the object isn't accelerating, velocity is constant

what does it mean when the line is going up at a constant rate on a velocity time graph

constant acceleration (positive gradient)

what does it mean when the line is going down at a constant rate on a velocity time graph

deceleration

what does the area under the curve represent on a velocity time graph

distance travelled

what does the gradient represent on a velocity time graph

acceleration

what does the gradient represent on a distance -time graph

speed

what does a straight line going up mean on a distance time graph

constant speed

what does a stationary line mean on a distance time graph mean

the object is stationary

what does a line getting steeper mean on a distance time graph

the speed is increasing

what does the area under the graph represent on a distance time graph

distance

what does the gradient represent on a distance time graph

speed
