What if there is no air resistance?
If there is no air resistance, after you let go of an object the only force on it is the gravitational force. The gravitational force is proportional to the mass of the object. The acceleration of an object is proportional to the net force on the object and inversely proportional to the mass of the object.
How do you 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.
How do you find speed without air resistance?
How to use the free fall formula: an example
- Determine the gravitational acceleration.
- Decide whether the object has an initial velocity.
- Choose how long the object is falling.
- Calculate the final free fall speed (just before hitting the ground) with the formula v = v₀ + gt = 0 + 9.80665 * 8 = 78.45 m/s .
Is it possible to have no air resistance?
When an object falls with air resistance, both its acceleration and speed change during its motion. When an object falls in a vacuum, there is no air resistance because there is no air in a vacuum.
How would rain fall if there was no air resistance?
If there were no air resistance, then the speed of the drops would be very high. The impact of the drops would be very high, so it would be dangerous for us to go outdoors on rainy days.
What’s an 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.
When there is no air resistance objects of different masses?
Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity. Under such conditions, all objects will fall with the same rate of acceleration, regardless of their mass.
How does air resistance affect raindrops?
Molecules in air constantly bombard with the object, exerting an upward force. This is known as air resistance or drag. As the object gains velocity there comes a time when the force of the air resistance is enough to balance the force of gravity, so the acceleration stops and the raindrop attains terminal velocity.
What is the terminal velocity of a drop of water?
When all the parameters are considered the terminal velocity of a typical raindrop is calculated to be about 9 meters per second or 20 mph. A smaller raindrop of radius 0.15 cm has a terminal velocity of about 7 meters per second or 16 mph.
How do you write air resistance force?
Air resistance force is also known as drag. The magnitude and the intensity of the air resistance force are directly proportional to the speed of the moving object. This means that the greater be the speed of the moving object, the bigger will be the air resistance force experienced by it.
How do you calculate air resistance force?
The units for the force of air resistance are in Newtons (N). Air resistance can be calculated by taking air density times the drag coefficient times area all over two, and then multiply by velocity squared .
How do you calculate the force of air resistance?

What are facts about air resistance?
Facts about Air Resistance 1: direction of straight object. The air resistance comes in up direction when it acts on the falling down object. The gravity will push the object down, but the air resistance pushes the object up.
What is the air drag equation?
The drag equation states that drag (D)is equal to a drag coefficient (Cd) times the density of the air (r) times half of the square of the velocity (V) times the wing area (A).
