If you get a question asking you to describe the rockets journey just brake the graph up in to equal sections and describe what you think the graph is showing in this

section.

At six seconds the air resistance is at its highest. This is because on the first

graph if you draw gradients at six seconds the gradient is at is steepest.

There for the air resistance is counteracting this and is at its peek at 6

seconds.

### Slide 5

Equations you may need

to know.

Change In Momentum=

Kinetic Energy= 1/ 2×Mass×[Velocity]² Resultant Force × Time for which

Speed = Distance ÷ Time it acts

[Velocity]²=Kinetic Energy

Distance =Speed×Time Resultant Force =Change In

1/ 2×Mass

Momentum÷ Time for which it

Velocity=Kinetic Energy

Time = Distance ÷Speed acts

1/ 2×Mass

Time for which it acts=Change In

Momentum÷ Resultant Force

Momentum= Mass× Velocity Work Done = Force ×Distance Change in GPE= Weight ×

Vertical Hight Difference

Mass=Momentum÷Velocity Force = Work Done÷Distance

Weight =Change in GPE÷

Vertical Hight Difference

Velocity = Momentum ÷ Mass Distance = Work Done ÷ Force
