What besides speed affects the air resistance on a skydiver?

Free fall occurs when only the force of gravity acts; no air resistance. … What, besides speed, affects the air resistance on a skydiver? Surface area, depending on body orientation; more area to the air, more resistance. How much air resistance acts on a falling 100N box of nails when it reaches terminal velocity?

What causes air resistance?

As an object falls through air, it usually encounters some degree of air resistance. Air resistance is the result of collisions of the object’s leading surface with air molecules.

What two types of forces contribute to the net force acting on a falling skydiver?

There are two forces acting on the falling skydivers. The first is the force of gravity (their weight) which we will denote as . The second is the force of air resistance pushing up against them which we will denote as .

What two principal factors affect the force of air resistance on a falling object?

When air resistance acts, acceleration during a fall will be less than g because air resistance affects the motion of the falling objects by slowing it down. Air resistance depends on two important factors – the speed of the object and its surface area.

Does mass affect air resistance?

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.

Is air resistance proportional speed?

Velocity and air resistance are proportional. Mathematically, sometimes it is proportional to the square of the velocity. Nonetheless, as velocity increases, so does air resistance.

What is speed and average speed?

What is average speed? Average speed is calculated by dividing the total distance that something has traveled by the total amount of time it took it to travel that distance. Speed is how fast something is going at a particular moment. Average speed measures the average rate of speed over the extent of a trip.

What forces are on a skydiver falling at a constant speed?

As her speed through the air increases, the air resistance also increases. At ‘terminal velocity’, which is about 200 km/h, the air resistance force balances the gravitational force and the parachutist stops accelerating and falls at constant velocity.

What is terminal speed when a skydiver has reached terminal speed what is the air resistance equal to what is the skydiver’s acceleration?

Terminal speed is the speed at which the force from the weight of the object equals the force of air resistance, so the acceleration is zero. When a skydiver reaches terminal speed, the air resistance is equal to the force of weight of the skydiver. At terminal speed, the sky diver’s acceleration is zero.

What is the force of air resistance on the skydiver once she reaches constant speed?

The object is not accelerating any more. It has reached its terminal velocity and is falling at a steady speed. The resultant force is zero because the frictional force acting against it is now the same as the weight of the object.
