What are two ways to increase air resistance of an object?
Increasing the surface area of the object, such as by adding flaps or a parachute, can increase air resistance. Additionally, increasing the object's speed will also increase the air resistance acting on it.
What can increase the speed of object?
Increasing the force applied to the object or reducing the air resistance can increase the speed of an object. Additionally, decreasing the mass of the object can also help increase its speed.
Why won't a skydiver's speed continue to increase until his or her parachute opens?
A skydiver's speed doesn't continue to increase indefinitely because of air resistance, which creates a "terminal velocity" where the force of air resistance balances the force of gravity. As the skydiver falls faster, air resistance increases until it matches the force of gravity, resulting in a constant speed.
How the force of air resistance deponds on an objects speed?
The force of air resistance increases with an increase in the speed of an object. This is because as an object moves faster through the air, it encounters more air particles, leading to more collisions and thus a greater air resistance force acting on the object.
Why parachutists do not fall with constant accelerating motion?
Parachutists do not fall with constant accelerating motion because air resistance increases as their speed increases. Eventually, the force of air resistance balances out with the force of gravity, causing the parachutist to reach a terminal velocity, where they fall at a constant speed.
