A skydiver jumps from a plane. They leave the plane at rest, and fall vertically downwards. However, they do not fall under acceleration due to gravity for their entre fall because of

• Their weight changes

• Air resistance increases downwards acceleration

• Air resistance reduces downwards acceleration
