Translation: Air resistance is a force that is caused by air. The force acts in the opposite direction to an object moving through the air. A lorry with a flat front will experience high air resistance while a sports car with a streamlined shape will experience lower air resistance, allowing the car to go faster.

What is air resistance and what affects it?
Air resistance depends on velocity, area, and shape of the object going through the air. Altitude, temperature, and humidity change air density and, consequently, its resistance. The higher the speed and the bigger the area, the higher the resistance.
What is air resistance called?
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid.
What is meant by air resistance answer?
Air resistance is a force that is caused due to air when an object moves through it. This force acts in the opposite direction to a body passing through the air.
What does air resistance depend on?
The amount of air resistance an object experiences depends on its speed, its cross-sectional area, its shape and the density of the air. Air densities vary with altitude, temperature and humidity.
What type of force is air resistance?
The air resistance is a special type of frictional force that acts upon objects as they travel through the air. The force of air resistance is often observed to oppose the motion of an object.
Why is it called air resistance?
Air resistance, also known as drag, is a force that is caused by air, the force acts in the opposite direction to an object moving through the air. It is where air particles hit the front of the object slowing it down. The more surface area, the more air particles hit it and the greater the resistance.
Do heavier objects fall faster?
Answer 1: Heavy objects fall at the same rate (or speed) as light ones. The acceleration due to gravity is about 10 m/s2 everywhere around earth, so all objects experience the same acceleration when they fall.
Why does air resistance happen?
Air resistance force happens when air is pushing against a moving object. Air resistance is a kind of frictional force. The force always occurs against the motion of an object. Secondly, the bigger the object, the more air resistance it will experience.
What is a example of air resistance?
Air resistance is a type of friction between air and another material. For example, when an aeroplane flies through the air, air particles hit the aeroplane making it more difficult for it to move through the air. It’s the same for an object moving through water.
How do I calculate air resistance?
Air resistance can be calculated by taking air density times the drag coefficient times area all over two, and then multiply by velocity squared.
What is air resistance force example?
Air resistance force plays a very important role in the action of a parachute. When a person jumps down while sky diving and opens up his/her parachute, the air resists the jump. Due to this resistance provided by the air, the speed with which the parachute approaches the ground slows down.
How do I calculate resistance?
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.
What is the work done by air resistance?
At the terminal velocity of the falling object, air resistance is equal to the force of gravity, and the object no longer accelerates. The work done equals the product of the force of gravity and the displacement of the object. It can also be determined by the change in potential energy of the object due to gravity.
Is air resistance affected by mass?
Air resistance is insignificant for heavy objects precisely because it doesn’t depend on the mass. Specifically, the change in motion due to air resistance gets bigger as the mass gets smaller.
