Motion of a parachute
When a person or an object falls from a great height, a parachute helps to slow down the fall of the person or object.
A parachute, which is shaped like an umbrella, makes the falling motion a slow and gradual process. This is because the air pushing against the parachute produces a lot of air resistance. However, if a person or an object falls from a great height without a parachute, the person or object falls faster because less air pushes against him or it.
Flashback:
- All objects fall at the same rate.
- Air resistance pushes against a moving object and slows it down.
1. The box falling from a great height has a parachute to prevent it from crashing to the ground. The box falls slowly due to more air resistance.
2. The same box without a parachute will fall to the ground faster because of less air resistances.
