When he first jumps, his weight is the only force acting on his body. As he accelerates, the air resistance force, which acts in the opposition direction to the weight, increases in magnitude. When these two forces equal, they cancel each other out, which means that the diver does not accelerate anymore. This speed is the terminal speed. It's all a matter of forces.

When a skydiver has reach the terminal speed what is the air resistance equal to what is the sky diver acceleration?

When a skydiver reaches terminal speed, the air resistance is equal to the force of gravity acting on the skydiver. At this point, the acceleration of the skydiver is zero, as the forces are balanced. This means that the skydiver is falling at a constant speed due to the opposing forces being equal.


Is a skydiver increasing or decreasing his speed during the first three seconds?

A skydiver is increasing their speed during the first three seconds of free fall due to gravity pulling them downwards. As the skydiver falls, their speed will continue to increase until they reach terminal velocity.


Is it true that the steady speed reached by a skydiver is called the terminal velocity?

Yes, that's correct. Terminal velocity is the constant speed that a falling object, like a skydiver, eventually reaches when the force of air resistance is equal to the force of gravity pulling the object downward. At this point, the skydiver no longer accelerates and falls at a constant speed.


What effect terminal velocity and air resistance have on a sky diver when he opens his parachute?

When a skydiver opens their parachute, air resistance increases which slows down the skydiver. Terminal velocity is the maximum speed a falling object can reach when the force of gravity is balanced by the force of air resistance. Opening the parachute decreases the skydiver's speed, allowing them to land safely.


Why do skydivers reach terminal velocity?

Skydivers reach terminal velocity because as they fall, the force of gravity pulling them downward is balanced by air resistance pushing upward. At terminal velocity, these forces are equal, so the skydiver stops accelerating and falls at a constant speed.


Why is a skydiver's speed wont continue to increase until his or her parachute opens?

A skydiver's speed doesn't continue to increase because of air resistance, also known as drag force. As the skydiver falls, the force of air resistance increases until it balances out with the force of gravity pulling them downwards. This causes the skydiver to reach a terminal velocity, the maximum speed they can achieve while falling, before the parachute opens.


When skydivers jump out of a plane they move down through the air faster and faster as they fall. Once they reach a speed of about 200 kilometres per hour they no longer speed up. Explain why.?

As a skydiver falls, they accelerate due to the force of gravity. However, they eventually reach their terminal velocity when the upward force of air resistance balances the downward force of gravity. At terminal velocity, the forces are balanced and the skydiver no longer accelerates.


What is the overall net force of a skydiver?

The overall net force acting on a skydiver is the force of gravity minus air resistance. Initially, as the skydiver falls, gravity is the dominant force causing acceleration. As the skydiver gains speed, air resistance increases, eventually balancing out the force of gravity to reach a terminal velocity where the net force is zero.


If a skydiver reaches terminal speed after ten seconds will the skydiver gain more speed during the first second or the ninth second?

I would imagine that it is uniform acceleration up until terminal speed. However, wind resistance will be higher 10000 feet up, so acceleration may be less at the start


How far do you have to fall to get to terminal velocity?

Terminal velocity is the constant speed that an object reaches when the force of gravity pulling it down is balanced by the force of air resistance pushing up on it. The actual distance required to reach terminal velocity varies depending on the object's mass, shape, and other factors. But in general, it takes around 1,500 feet for a skydiver to reach terminal velocity.


Why several seconds after jumping from an aircraft a skydiver will be travelling at a constant speed?

After jumping from an aircraft, a skydiver falls due to gravity. As they fall, the force of gravity accelerates them until they reach what is called terminal velocity. At this point, the force of air resistance pushing up against them equals the force of gravity pulling them down, resulting in a balanced force and a constant speed.


Why won't a skydiver's speed continue to increase until his or her parachute opens?

A skydiver's speed doesn't continue to increase indefinitely because of air resistance, which creates a "terminal velocity" where the force of air resistance balances the force of gravity. As the skydiver falls faster, air resistance increases until it matches the force of gravity, resulting in a constant speed.
