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

It is a type of acceleration that describes the

speeding up of an object

It is the rate of change of velocity

It is a type of acceleration that describes the

slowing down of an object

What is the formula of velocity?

What is the formula of Acceleration?

What is the formula of Time?

A train is initially travelling at a speed of 50 m/s. It accelerates to a speed of 70 m/s in 5 seconds, what is the initial velocity of the train?

A train is initially travelling at a speed of 50 m/s. It accelerates to a speed of 70 m/s in 5 seconds, what is the final velocity of the train?

A train is initially travelling at a speed of 50 m/s. It accelerates to a speed of 70 m/s in 5 seconds. How many seconds does the train travels?
