Understanding Acceleration and Velocity

It is a graph that shows the relationship between

the velocity of an object over time; time is

plotted on the x-axis and the velocity of the

object is plotted on the y-axis

• Velocity vs time graph

• Acceleration vs time grraph

• Speed vs time graph

It is a type of acceleration that describes the

speeding up of an object

• Positive Acceleration

• Negative Acceleration

• Zero Acceleration
