A skydiver loses which type of potential energy as she falls?
She loses gravitational potential energy.
When a skydiver falls the air is forced to move around him. What energy transformation does this cause?
As the skydiver falls, the moving air around them causes the conversion of the skydiver's gravitational potential energy into kinetic energy. This is because the air resistance exerts a force on the skydiver, causing work to be done and energy to be transferred from potential to kinetic.
When a skydiver jumps out of a hovering helicopter so there is forward velocity. what is the skydiver's acceleration?
Initially, the skydiver will experience an acceleration due to gravity, which is approximately 9.81 m/s^2 downward. As the skydiver falls, air resistance will oppose this acceleration, causing the skydiver to reach a terminal velocity where the downward acceleration due to gravity is balanced by the upward force of air resistance.
What is a skydivers velocity after 2 seconds?
Acceleration due to gravity is 9.8m/s/s, which is the same as 9.8m/s2. An acceleration of 9.8m/s/s means that with each passing second, the velocity of the skydiver increases by 9.8m/s. Therefore, after two seconds. a skydiver's velocity would be 19.6m/s. The acceleration will continue at 9.8m/s/s until the skydiver reaches terminal velocity, at which point the weight of the skydiver and the air resistance will be balanced, so the net force acting on the skydiver will be zero, at which point there will be no further acceleration.
A skydiver of mass 100 kg experiences air resistance while falling How fast is the skydiver being accelerated at?
The acceleration of the skydiver can be calculated using Newton's second law: F = ma, where F is the force of gravity - air resistance, m is the mass of the skydiver, and a is the acceleration. The acceleration will depend on the exact value of air resistance acting on the skydiver.

Are people weightless in the air?
No. Things are only weightless in the absence of a gravitational field or in constant acceleration (Inertial weight or mass) (Ask any skydiver.)
Why does the accleration of sky diver decrease with time?
The acceleration of a skydiver decreases over time due to the increasing air resistance or drag acting against the force of gravity. As the skydiver falls, their velocity increases, leading to greater drag force until it eventually balances the gravitational force. At this point, the skydiver reaches terminal velocity, where acceleration becomes zero and they fall at a constant speed.

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.
What happens when a Skydiver Jumps Out Of A Hovering Helicopter So There Is Forward Velocity. What Is The Skydiver's Acceleration?
When a skydiver jumps out of a hovering helicopter with forward velocity, the skydiver's initial velocity will be a combination of the helicopter's forward velocity and the vertical velocity due to gravity. As the skydiver falls, their acceleration is primarily due to gravity acting downward, with air resistance also playing a role. The acceleration experienced by the skydiver will be constant at approximately 9.8 m/s^2 downward, ignoring air resistance.
Does it mean a skydiver is slowing down if the acceleration of the skydiver decreases as falling progresses?
No.Acceleration is a measure of the rate of change of velocity (speed & direction). If acceleration is decreasing (but still above zero) then this means that the rate at which the speed is increasing in this direction is decreasing.As long as the downward acceleration is greater than zero then the skydiver's speed is still increasing.Once terminal velocity is reached then downward acceleration will equal zero (speed is constant).If the downward acceleration falls below zero (as will happen once his parachute is deployed for instance) then this means he is slowing down.
What is the magnitude of a skydiver's acceleration if it takes 0.75 seconds?
zero
As a skydiver fallsthe air is forced around him.what energy transformation doe's this cause?
As the skydiver falls, the air resistance forces kinetic energy to be transformed into thermal energy due to friction between the air and the skydiver's body. This reduces the speed of the skydiver as they fall towards the ground.
