What does air resistance do in physics?
Definition: By definition, air resistance describes the forces that are in opposition to the relative motion of an object as it passes through the air. These drag forces act opposite to the oncoming flow velocity, thus slowing the object down.
What is air resistance in physics in simple words?
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.
How do you calculate air resistance in physics?
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 the force of air resistance?
The force exerted by the air on things moving through it is known as air resistance. This force is commonly referred to by scientists as drag or drag force. Typically, this force is applied in the opposite direction as the object’s motion, slowing it down. The frictional force of air resistance acts on the moving body.
How do you calculate the air resistance of a moving object?
So, the shape of the object influences the value of “b”, the density of the fluid influences “b”, and so on. This means that we can write the air resistance force (or drag force) as f drag = bv for very small, slow objects, or f drag = bv 2 for “human-size objects, depending on the situation. Terminal Velocity.
What factors affect the air resistance of an object?
Previously, we saw that the air resistance force on an object depends primarily on the relative velocity of the object and the fluid the shape of the object the density of the fluid other properties of the object, such as surface texture, as well as other properties of the fluid, such as viscosity The Air Resistance (Drag) Force
What is air (fluid) resistance?
(AP Level) The purpose of this page is to take a more mathematical look at air (fluid) resistance (also called drag or the drag force) and terminal velocity. Previously, we saw that the air resistance force on an object depends primarily on the relative velocity of the object and the fluid the shape of the object the density of the fluid
