Why a skydiver falls towards earth even when he is under the influence of balance forces?
"Balanced forces" doesn't mean that an object doesn't move. "Balanced forces" means that the vector sum of forces on an object is zero. Now, according to Newton's First Law, if no force is acting on an object, if that object is at rest it will continue being at rest; if it is moving, it will continue moving with the same velocity. In other words, there will be no CHANGE in velocity; that doesn't mean that the velocity must necessarily be zero.

What happens when the gravitational forces of the Sun and the moon combine?
When the gravitational forces of the Sun and the Moon combine, it results in tidal forces on Earth. These tidal forces cause the ocean water to bulge out towards the Sun and the Moon, creating high and low tides. The Sun and Moon's gravitational forces work together to influence the Earth's tides in a complex way.
Why do planets and their moons stay in orbit?
Planets and their moons stay in orbit due to a balance between gravitational forces pulling them towards each other and the forward motion of the objects. This balance causes them to continuously fall towards each other but also keep moving sideways fast enough to not collide. This results in stable orbits around a common center of mass.
The balance of forces that keeps a star from collapsing is called .?
hydrostatic
What do you call The balance of forces that keeps a star from collapsing?
Dynamic equilibrium.
How are falling apples and the orbit of the Moon alike?
Both involve gravitational forces. Falling apples are pulled towards the Earth's center by gravity, while the Moon is kept in orbit around the Earth by the gravitational force between the two celestial bodies.
What forces work on a skydiver?
(standard air pressure and gravity)>(Constant) Force down (newtons) = mass * acceleration due to gravity>Say 70 kg skydiver @ 9.82 m/s/s = 70 * 9.82 = 687.4 newtons>Force up (newtons) = velocity 2 * drag coefficient (say 0.16 typical)>Terminal velocity (when forces balance) 687.4 = v 2 * 0.16Terminal velocity = square root (687.4 / 0.16)= 65.546 metres per second ( 147 mph) terminal velocity
What is the physics involved in skydiving?
Skydiving involves concepts from Newton's laws of motion, particularly the forces of gravity and air resistance. When a skydiver jumps out of a plane, gravity pulls them towards the Earth, creating acceleration. As the skydiver falls, air resistance pushes upward against gravity, eventually reaching a point where these two forces balance out, leading to a constant terminal velocity. This terminal velocity is the speed at which the forces of gravity and air resistance cancel each other out, allowing the skydiver to fall steadily until reaching the ground.
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.
Are the forces balanced or unbalanced when a skydiver is accelerating downward?
When a skydiver is accelerating downward, the forces are unbalanced. The force of gravity acting downward on the skydiver is greater than the air resistance force pushing upward, causing the skydiver to accelerate downward.
A skydiver who weighs 500 N reaches terminal velocity of 90kmh the air resistance on the diver is then?
The air resistance on the skydiver at terminal velocity is 500 N. At terminal velocity, the air resistance on the skydiver is equal in magnitude to the gravitational force pulling them downward. This balance of forces results in a constant velocity.
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.
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.
What are the forces acting on a skydiver?
The main forces acting on a skydiver are gravity, which pulls the skydiver downward, and air resistance (drag), which acts in the opposite direction of motion. As the skydiver falls, air resistance increases until it balances out the force of gravity, leading to a constant velocity known as terminal velocity.
When the two forces acting on the skydiver are balanced what acceleration does?
When the two forces acting on the skydiver are balanced, the acceleration is zero. This occurs when the force of gravity pulling the skydiver downward is equal to the air resistance acting upward. At this point, the skydiver reaches terminal velocity, meaning they will continue to fall at a constant speed without accelerating further.
When a skydiver jumps out of an airplane there are two forces acting on her gravity and air resistance After falling for a few seconds the forces due to gravity and air resistance balance each other?
Your question is slightly confusing as you seem to have answered it yourself. A little extra though, the speed at which the skydiver is now travelling is called terminal velocity and it is the fastest an object can travel with only gravity + air resistance acting on it as forces. Due to differing air resistances everything has its own unique terminal velocity and it is possible to alter it, this is the principle behind a parachute.
What is an example of an free fall?
A rock that is dropped, and a apple falling from a tree.Hold a ball in your hand, stretch out your arm, and drop the ball. As it is moving towards the ground, it is in free fall.
How much air resistance acts on a 500 N skydiver that falls at her terminal velocity?
500 N is pressumably the weight, due to gravity. "Terminal velocity" means that the forces are in balance; the total force acting on the skydiver are zero. This is only possible if there is a 500 N force due to friction, to counteract the weight.
