How is cumulative effect of gravity and air resistance related to an objects termianl velocity?
The cumulative effect of gravity and air resistance determines an object's terminal velocity. Initially, gravity accelerates the object, while air resistance acts in the opposite direction. As the object gains speed, air resistance increases until it becomes equal in magnitude to the force of gravity. At this point, the net force on the object is zero, resulting in a constant terminal velocity where the forces are balanced.
Does vibration affect terminal velocity?
Vibration does not have a significant effect on terminal velocity. Terminal velocity is the constant speed that an object reaches when the force of gravity pulling it down is equal to the force of air resistance pushing against it. Vibrations are typically not strong enough to significantly alter this balance.
Does a larger sphere have a higher terminal velocity?
Not necessarily. Terminal velocity depends on a combination of factors like weight, drag coefficient, and surface area. So while a larger sphere may experience more air resistance due to its increased surface area, it might also be heavier, which can offset this effect.
What happens to an object when it reaches terminal velocity?
If someone is skydiving, the terminal velocity would be the greatest velocity reached by the falling person until they open their parachute. So in that case, the effect would be slowing down because of the parachute. The effect may vary from different cases.
How Can A Skydiver Increase his or her terminal velocity?
The less air resistance the faster he can go. By pointing his face or feet down and holding his arms close to his body he minimizes air resistance and falls faster. By positioning his body parallel to the ground and spreading out his limbs he maximizes air resistance and will fall slower. The type of clothing worn also has an effect. A loose fitting fabric jumpsuit will tend to reduce terminal velocity and a tight fitting nylon jumpsuit will increase it. Some jumpers wear lead weight to adjust their fallrate. This is usually so slim light jumpers can match their fallrate with heavier jumpers.
Are you in free fall if you use a parachute?
interesting: in effect you are, because you have reached the terminal velocity for your surface area, which happens to be very large! if wrong, someone please correct me.

Compare the effects of gravity and air resistance on a falling skydiver before and after she opens her parachute.?
-- The force of gravity is unchanged before and after.-- The force of air resistance on the skydiver is greater before, and less after,because she is falling slower after the parachute opens.-- The effect on her of air resistance is greater after the parachute is open. Theincreased air resistance itself acts on the parachute, and its effect is transferredto the skydiver through her harness.

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.
How is the size of parachute effect by air resistance?
The size of the parachute affects air resistance because a larger parachute will have more surface area interacting with the air, creating more drag. This drag helps to slow down the descent of the object attached to the parachute. Conversely, a smaller parachute will generate less air resistance and may result in a faster descent.
What effect does the force of gravity have on the ball thrown upwards?
The ball returns to the ground with increasing velocity due to acceleration due to gravity. At a point (terminal velocity) the ball maintains a constant velocity (due to air resistance) This occurs when the weight of the ball is equal to the viscous drag of the air (air resistance) and upthrust (weight of air displaced).

What determines the terminal velocity of an object?
Gravity and drag. Gravity accelerates the object and drag (caused by friction) slows it down. When the full effect of these two forces have been applied to an object, that object is said to have reached terminal velocity. A combination of mass, the size of the leading surface area and the shape of the object determine it's velocity. Example: A man with a closed parachute falls faster than a man with an open parachute.
