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.
Why does it take longer for the parachute to reach the ground?
Because the parachute is catching the air, slowing down the fall
Can a person parachute without a parachute?
yes it is possible to parachute without a "parachute" there is a suit which u wear called a squirrel suite i believe which allows the air to be caught acting as a "brake" there for slowing you down but i am not sure if it works completley
What happens immediately after skydiver opens her parachute?
When her parachute opens, the air resistance increases. Now there is a resultant force going upwards on the parachute. The increase in air resistance occurs because when the parachute is opened there is a much larger surface area (than before) so the particles of air are much more likely to get 'caught up' in the parachute unable to pass easily, therefore creating more air resistance (an upwards force) and so slowing down the parachutist. NOTE: The parachutist does NOT move upwards after the parachute has opened, they just slow down. This effect comes from when a parachutist with a camera is filming opposite, they are still falling rapidly while the other person's parachute has opened, therefore passing them as they continue to freefall, and so the parachutist opposite appears to move upwards after opening the parachute.
How does forces affect the sport of sky diving?
Gravity pulls the skydiver towards the centre of the earth (downwards force). The air causes wind resistance, slowing the sky diver down (upwards force). The wind can also cause a slight sideways force upon the skydiver.
How does a parachute reduce the terminal velocity of a person falling through the air?
The parachute increase the surface area and so therefore increase air resistance, slowing the person down, and reducing terminal velocity.
How an car related to physics?
Kinetic energy- capable of movement. Inertia, when moving, and friction-brakes when slowing down.
What makes the earth go around?
Inertia. The Earth was set spinning when it was formed, and this has simply continued, gradually slowing.
What force slows moving objects?
Inertia is what slows down moving objects. 2nd Answer: Not even close . . . inertia would keep objects FROM slowing. Friction or running into another object will slow a moving object.
Inertia is what to mass?
Inertia is a bodies resistance to velocity change upon application of a force, so essentially its directly proportional to its mass.
Using running parachute to improve speed and strength?
Attaching a parachute to you while you run will catch wind/air, slowing you down. This resistance will make you have to run faster and harder than normal, making your running regimen more intense and effective.
How do parachutes help skydivers land safely?
The large area of a parachute canopy increases wind resistance greatly, slowing the fall, and permitting the skydiver to steer towards a landing spot.when the skydiver jumps out of the plane his weight makes him accelerate, soon the air resistance balances out the forces, but his terminal velocity is too great for him to land safely, son he opens a parachute, the parachute makes the air resistance greater, as it has a larger surface area. soon the air resistance, and the weight are balanced, but now the parachutist is going slowly enough to land safely, and not kill himself.air resistance increases greatly when the parachute is opened and that results in the deceleration of the skydiver; As a result, The skydiver will reach a speed appropriate for landing safely.The canopy (parachute) has multiple cells. The nose (front) of the canopy is open but the back is closed which pressurises the canopy during forward flight and thus maintains the aerodynamic shape of the canopy which generates lift.The slider, a square shaped fabric with four round gommits in the corners separates the lines, the lines from the nose to the front and those from the steering brake line to the rear. The slider slows the opening down so that the deceleration is controlled.The canopy is controlled by pulling on the toggles, the left toggle for a left turn and visa versa.A final turn is made relatively close to the ground so that the landing is into wind, thus reducing the ground speed and just prior to landing, the skydiver pulls down on both toggles to induce a flare which slows and stalls the canopy for a generally soft stand up landing.By creating a large surface that has a high wind resistance, a parachute slows the fall of a sky diver- and permits them to guide the direction of their descent. Falling slower = good.i think that it balances out the force of gravity pulling you down with air resistance so you reach the ground at a sensible speed hence not getting hurt.
