## What happens when a skydiver reaches terminal velocity?

Air resistance is pushing up on the parachute and force of gravity is pulling down so she slows down. This increases friction which slows free fall down. So when the skydiver reaches terminal velocity, the force of gravity is balance by air resistance. But when the forces are balance, there is no acceleration.

## What forces act on a skydiver?

The main forces acting on a parachute are gravity and drag. When you first release the parachute, the force of gravity pulls it downward, and the parachute speeds toward the ground. The faster the parachute falls, though, the more drag it creates.

## What direction is the net force on a falling skydiver before she reaches terminal velocity?

The net force and the acceleration on the falling skydiver is upward. An upward net force on a downward falling object would cause that object to slow down. The skydiver thus slows down. As the speed decreases, the amount of air resistance also decreases until once more the skydiver reaches a terminal velocity.

## Can an object move when its acceleration is zero?

4) a) Can an object be moving when its acceleration is zero? … Yes, an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration, i.e. it is moving at constant velocity.

## What animals can survive terminal velocity?

Any rodent the size of a squirrel or smaller can survive terminal velocity. Bears and mountain lions cannot, but seem ok after landing on their head from a tree height according to videos. This is a cat falling 80 plus feet on to concrete and walking away.

## Does terminal velocity exist in a vacuum?

The velocity at which the accelerating force and the velocity-dependent drag force are at equilibrium is known as the terminal velocity. In vacuum since there is no drag force, the terminal velocity does not exist.

## What are the 2 forces acting on a skydiver?

There are two forces acting on a parachute with a parachutist: the force of gravity and the air resistance.

## What happens to an object if the forces are balanced?

If the forces on an object are balanced (or if there are no forces acting on it), this is what happens: a stationary object stays still. a moving object continues to move at the same speed and in the same direction.

## What force slows down a skydiver?

Air resistance is the frictional force acting on an object (the skydiver) and the air around them. Frictional forces always oppose motion (1). This means that friction always pushes in the opposite direction than the skydiver is travelling, therefore slowing the skydiver down.
