Terminal velocity is the maximum speed an object will attain, when all of the forces acting on it are balanced. A falling person has 2 forces acting on him: gravity and air resistance.
Gravity is a relatively constant force and will remain the same during the entire fall (9.8m/s^2). The force due to air resistance increases as you travel faster. Therefore, as the person falls faster and faster, the force due to air resistance will increase until it is the same (but opposite direction) as gravity (meaning the person will not accelerate, and will travel at a constant speed/velocity).
If this person has no parachute, they will have a low surface area for the air resistance to push on. This means they will reach a very high terminal velocity for the air resistance force to balance out gravity. A parachute greatly increases the surface area for air resistance to act and means that the person will not reach as high of a speed for the forces to balance out.
Try this: swipe your hand through a body of water (like a pool or bathtub) with your fist clenched. The try again with your hand opened, but fingers together. The open hand will have more resistance (which means more force acting back on it) and will not reach the same velocity.
What else can I help you with?
Is terminal velocity the highest velocity that a falling object will reach?
Yes, terminal velocity is the highest velocity that a falling object will reach when the force of air resistance equals the force of gravity acting on the object, causing it to no longer accelerate. At terminal velocity, the object falls at a constant speed without further acceleration.
Can terminal velocity cost death?
Terminal velocity is the speed at which air friction produces enough drag to balance the effect of gravity and cease acceleeration (keeping the subject at a constant speed downward). For an unaided person, it is almost certain death since t.v. for us is about 200km/h. However with a parachute we are slowed to speeds at which we will easily survive.
When a falling object has reached terminal velocity it continues to gain what?
When a falling object has reached terminal velocity, it no longer accelerates due to air resistance matching the force of gravity. At this point, the object continues to fall at a constant speed without gaining any additional velocity.
How does air resistance affect terminal velocity?
Air resistance increases as an object's speed increases. At terminal velocity, the upward force of air resistance equals the downward force of gravity, resulting in a constant velocity. The greater the air resistance, the lower the terminal velocity of an object falling through the air.
An object is falling at its what if it falls at a constant velocity?
If an object is falling at a constant velocity, then the net force acting on it is zero. This means that the force of gravity pulling the object downward is balanced by an equal and opposite force. The object will continue to fall at a steady speed without accelerating.
Is terminal velocity the highest velocity that a falling object will reach?
Yes, terminal velocity is the highest velocity that a falling object will reach when the force of air resistance equals the force of gravity acting on the object, causing it to no longer accelerate. At terminal velocity, the object falls at a constant speed without further acceleration.
How fast do skydivers fall through the the air?
A skydiver, falling without an open parachute, will reach a terminal velocity of approx 200 km per hour (55 metres/second).
Can terminal velocity cost death?
Terminal velocity is the speed at which air friction produces enough drag to balance the effect of gravity and cease acceleeration (keeping the subject at a constant speed downward). For an unaided person, it is almost certain death since t.v. for us is about 200km/h. However with a parachute we are slowed to speeds at which we will easily survive.

Air resistance increases as an object's speed increases. At terminal velocity, the upward force of air resistance equals the downward force of gravity, resulting in a constant velocity. The greater the air resistance, the lower the terminal velocity of an object falling through the air.
What is the terminal velocity of body in a freely falling system?
Assuming the object starts at rest, it is zero. However, if the object is thrown upward or downward, its inital velocity will not be zero.
An object is falling at its what if it falls at a constant velocity?
If an object is falling at a constant velocity, then the net force acting on it is zero. This means that the force of gravity pulling the object downward is balanced by an equal and opposite force. The object will continue to fall at a steady speed without accelerating.
What are examples of free fall?
An object dropped from a height without any initial velocity, a skydiver falling towards the ground before deploying their parachute, and a rock falling off a cliff are all examples of free fall.
What is the definition for terminal velocity?
As an object falls faster and faster it is slowed by friction with the air as it tries to push through. When this wind from falling is so strong that it balances gravity, so the object does not fall any faster, that it is the terminal velocity for that object.
What are two ways of increasing the terminal velocity of a falling object?
I'm reluctant to answer because the wording of the question suggests the person asking is looking for answers that meet undefined constraints. One way to increase the terminal velocity of a falling object is to drop it in a vacuum. Another is to drop it in a atmosphere of hydrogen. . 1. increase the mass, without increasing the drag coefficient. 2. Decrease the drag coefficient, without decreasing the mass.
How many feet does it take to reach terminal velosity?
Terminal velocity is the constant speed an object reaches in free fall when the force of gravity is balanced by air resistance. The distance it takes to reach terminal velocity depends on the object's weight, shape, and air density. Generally, it can take a few thousand feet for a skydiver to reach terminal velocity.
Why a person without a parachute falls fast than a person without a parachute falling from same height?
if there is no air then both will take same time.But due to presence of air person who is without parachute will take less time.
