because there is more air resistance

Will a man in a parachute when the air resistance is less than his weight accelerate?
Yes, until he reaches terminal velocity.
When an object is released in a fluid is the drag force less than its weight before it reaches terminal velocity?
When an object is released in a fluid is the drag force less than its weight before it reaches terminal velocity?
Why is the terminal velocity in water less than the terminal velocity in air?
More resistance, caused by a greater density.
When you skydive Why don't you hit maximum speed before you hit the ground?
The maximum speed you can reach is also known as terminal velocity and this is the speed at which your mass is resisted by the air. Typically in a belly to earth body position, this is around 120mph. It takes around 10 seconds to reach this speed. The minimum exit height is 2500ft and would not reach this terminal velocity before they need to deploy their parachute. Most skydivers jump from a lot higher - between 10,000ft and 15,000ft. This gives them a freefall time of over 45 seconds and therefore they reach terminal velocity. Once the parachute is open, the decent rate is less than 10mph, so no you do not hit the ground at maximum speed in answer to your question.
Why is terminal velocity in water less than the terminal velocity in air?
The incompressibility, inertia and relatively higher viscosity of water make it difficult to displace, so its reactive forces on the falling object are greater; hence the terminal velocity is reduced.
Which is greater - the terminal velocity of a small blood droplet or the terminal velocity of a large blood droplet?
The small blood droplet would have a greater terminal velocity. The smaller droplet has a smaller surface area, thus suffers less air resistance.
What is the maximum terminal velocity on planet Jupiter?
There is no such thing as "maximum terminal velocity", neither on Jupiter nor hear on Earth. The "terminal velocity" depends on the specific object - and on the atmospheric conditions. For example, a very heavy object will typically have a larger terminal velocity than one that is very light; and near Earth's surface, the terminal velocity (for a given object) will be smaller than in the upper atmosphere, where there is less air resistance.
Why fog droplets appear to be suspended in air?
its because the terminal velocity is directly proportional to mass and square of the radius of the drop. the radius and mass of the droplet is very very less...so terminal velocity of the droplet is also very less.. that why it is suspended in the air..
What does high velocity blood spatter means in a crime scene?
High Velocity is short for "high terminal velocity" which is another way of saying that the blood spatter is small and is so small, in fact, it is the smallest of other velocities: • Low terminal velocity • Medium terminal velocity The high velocity pattern is usually less than one millimeter in diameter and is known to fall up to around 100 feet per second.
What is one example of an outside force that slows down moving objects?
A parachute. Nothing more, nothing less.
What is terminal velocity and how to control it and why it occurs?
Terminal velocity is when air resistance balances out with gravity. For humans it's usually around 2000 ft of falling, gravity accelerates the person towards the ground at about 9.8m/s, as said person speeds up, air resistance increases and it becomes harder to accelerate. Terminal velocity is the point at which one may no longer accelerate. To control it: more air resistance = slower descent (terminal velocity comes sooner and is not as fast (i.e.parachutes), less air resistance = faster descent, it may take longer to reach terminal velocity as it is a much higher speed.
Is there a sonic boom during fall?
Usually not. Most objects have a terminal velocity that is considerably less than the speed of sound.
