Exploring the effect of multiple forces on an object, the Year 5 Koala Class experimented to
VIDEO
investigate the forces acting on a handmade parachute.
A parachute experiences four main forces during its descent. VIDEO
1. Gravity pulls the parachute and any attached objects toward the Earth, causing it to de-
HERE
scend.
2. Air resistance, or drag, acts in the opposite direction, slowing down the parachute’s de- HERE
scent. A larger surface area and shape of the parachute affect the amount of air resist-
ance it experiences.
3. Additionally, the air flowing over and under the parachute creates a lift that helps keep it
stable during its descent.
4. Finally, the weight of the air itself exerts a force on the parachute, known as air pressure,
adding to the overall resistance experienced by the parachute.
