## How does air resistance affect free fall?

With air resistance, acceleration throughout a fall gets less than gravity (g) because air resistance affects the movement of the falling object by slowing it down. How much it slows the object down depends on the surface area of the object and its speed.

**What is the equation for free fall?**

The formula for free fall: Imagine an object body is falling freely for time t seconds, with final velocity v, from a height h, due to gravity g. It will follow the following equations of motion as: h= \frac{1}{2}gt^2. v²= 2gh.

**Does free falling have air resistance?**

Free-fall is the motion of objects that move under the sole influence of gravity; free-falling objects do not encounter air resistance. The actual explanation of why all objects accelerate at the same rate involves the concepts of force and mass.

### What is the formula for calculating air resistance?

The net external force is equal to the difference between the weight and the drag forces (F = W – D). The acceleration of the object then becomes a = (W – D) / m . The drag force depends on the square of the velocity.

**How do you find the air resistance of a falling object?**

- An object that is falling through the atmosphere is subjected to two external forces. The first force is the gravitational force, expressed as the weight of the object, and the second force is the aerodynamic drag of the object.
- W = m * g.
- D = Cd * .5 * r * V^2 * A.
- F = m * a.
- a = F / m.
- F = W – D.
- a = (W – D) / m.

**What is free fall example?**

Examples of objects in free fall include: An object dropped at the top of a drop tube. An object thrown upward or a person jumping off the ground at low speed (i.e. as long as air resistance is negligible in comparison to weight).

## How do you find the net force of a falling object with air resistance?

**How do you calculate the force of a free falling object?**

By calculating the change in momentum between the fall and the bounce and dividing the result by the amount of time between these two points, you can get an estimate for the impact force.

**How do you calculate free fall velocity?**

Velocity (v) can be calculated via v = gt, where g represents the acceleration due to gravity and t represents time in free fall. Furthermore, the distance traveled by a falling object (d) is calculated via d = 0.5gt^2.
