2. Describe how the forces acting on a skydiver change throughout a parachute jump. (6)
The only two forces acting on the skydiver are weight and air resistance.
The one force that doesn’t change is weight because the skydivers mass doesn’t change.
The instant the skydiver jumps from the plane air resistance is low so weight pulls him down.
Resultant force is down.
The further you fall, the faster you fall.
As the skydiver falls he accelerates so air resistance increases.
Resultant force now is still down, but smaller.
Eventually the two forces become balanced because air resistance equals weight.
Resultant force now is zero.
The skydiver now falls at terminal velocity.
The skydiver pulls his parachute so speed decreases as air resistance increases because surface area has increased.
Resultant force now is up as air resistance is bigger than weight.
Resultant force now is zero again.
The skydiver now falls at a lower, terminal velocity.

32. Compare and contrast the processes of nuclear fusion and nuclear fission. (6)
Both processes produce vast amounts of energy.
Both processes involve nuclei.
Fission splits heavy nuclei into smaller nuclei whilst fusion joins small nuclei to produce heavier nuclei.
The products of uranium fission are Barium and Krypton nuclei whereas the product of fusion is Helium nuclei.
Fission leaves behind radioactive waste whilst fusion produces no harmful products.
Fission can be used to generate electricity whilst fusion only naturally occurs in stars.
Fission can be dangerous because it can lead to an uncontrollable chain reaction, leading to nuclear meltdown or explosions.
Whilst fusion, when man-made, is safe because as soon as a problem arises, the system shuts down.
