What are the amount of forces acting against a skydiver at the start of his jump?
Small air resistance, Gravity is large
Gravity is small, Air resistance is big
Friction is big, Gravity is small
As the skydivers speed increases, what are the amounts of force acting against him?
Air resistance increasing, Gravity big
Gravity increasing, Air resistance big
Friction increasing, Gravity small
What will happen after his speed increases?
The air resistance and gravity will balance the skydivers weight. Terminal velocity
When the parachute is opened. What will the forces be like?
Air resistance suddenly increases, starts to slow down
Air resistance suddenly increases, starts to speed up
What will happen after this?
It will reach a new LOWER terminal velocity
It will reach a new HIGHER terminal velocity
When a rocket flies away from the Earth, what is the force like?
Large force as the Rocket leaves Earth
Small force as the Rocket leaves Earth
When a Rocket reaches Space, what will the force be like to power the Rocket?
Big force
Small force

Deaccelerating
A horizontal line, on a graph, represents what?
Decelerating speed
A small diagonal line on a graph, represents what?
Accelerating Speed
