Air resistance, also known as drag, increases with speed because the faster an object moves through the air, the more air molecules it must push aside. This results in a greater force acting in the opposite direction of motion, ultimately slowing down the object.

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.
How does water or air resistance against an object increase speed?
It doesn't increase speed. The word resistance means to resist. In other words it decreases speed.

What increases the speed of a pendulum?
Increasing the length of the pendulum or increasing the angle from which it is released will increase the speed of a pendulum. Additionally, reducing air resistance can also lead to an increase in the speed of a pendulum.
Can air resistance affect the distance that a toy car does?
Yes, air resistance can affect the distance a toy car travels. A toy car moving through the air experiences air resistance, which can slow it down and reduce its overall distance traveled. Increasing the car's speed may also increase the impact of air resistance.
How does air pressure affect speed of a human?
High air pressure creates denser air, which can increase air resistance on a person's body and slow them down when moving. Conversely, low air pressure creates thinner air, which can reduce air resistance and potentially increase speed. However, the impact of air pressure on a human's speed is minimal compared to other factors such as fitness level and technique.
Which direction does the parachutist go if gravity is greater than air resistance?
If gravity is greater than air resistance, the parachutist will accelerate downward and continue to fall towards the ground. The air resistance will slow down the parachutist's descent, but since gravity is stronger, the overall motion will be downward.
What increases as the speed of an object increases?
As the speed of an object increases, its kinetic energy and momentum also increase. Additionally, the drag force acting on the object due to air resistance will also increase with speed.
How do you stop air resistance?
Air resistance can be minimized by reducing the surface area of the object moving through the air, such as by adopting a streamlined shape. Another way is to increase the object's speed, as air resistance depends on the square of the object's speed. Finally, lowering the air density or using specialized materials can also help reduce air resistance.
