Fired ammunition from a firearm reaches a much higher initial velocity due to explosive propellant forces. In contrast, ammunition dropped from a high altitude reaches a terminal velocity where gravity pulling down is balanced by air resistance pushing up. The fired bullet maintains its higher velocity until slowed by air resistance and gravity, while dropped ammunition reaches a constant speed due to these opposing forces.
What else can I help you with?
How long does it take for an egg to reach terminal velocity?
An egg would typically reach terminal velocity in about 12 to 15 seconds when dropped from a significant height. Terminal velocity is the point at which the force of gravity on the egg is equal to the force of air resistance, causing the egg to no longer accelerate.
Is terminal velocity the same speed for any weight?
Terminal velocity for a feather will be considerably lower than the terminal velocity of a bullet. The size and shape of the object will play an important role. While objects dropped from a given height in a vacuum will fall to earth at the same velocity, the resistance caused by atmosphere will be different for different objects.
How do you calculate the point that a dropped coffee filter hits its terminal velocity?
Terminal velocity on earth is static for all objects. A coffee filter being so light would have an effect on how much the friction slows it down, it would not however change its "terminal velocity" in a vacuum it would fall at the same rate as you or I. Approximately 120 MPH.
Velocity time graph for a body dropped from a certain height?
The velocity-time graph for a body dropped from a certain height would show an initial spike in velocity as the object accelerates due to gravity, reaching a maximum velocity when air resistance equals the force of gravity. After this, the velocity would remain constant, representing free fall with a terminal velocity. When the object hits the ground, the velocity suddenly drops to zero.
The point at which an object is falling at the fastest it can go is called its velocity?
When objects fall gravity causes them to increase their speed. The speed would continue to increase if there was no atmosphere. But the atmosphere causes friction which prevents the object from continually increasing its speed. At some point in the fall the object reaches what is called its "terminal velocity". This is the maximum speed it reaches when the frictional force prevents it from going any faster. The terminal velocity of falling objects depends on their shape and mass so it is different for different objects. Also some objects take a long time to reach their terminal velocity so they have to be dropped from very high up in order to have time to reach terminal velocity before hitting the ground.
When a pearl is dropped into a dense liquid it quickly acquires a uniform non accelerated motion downward why does this happen?
It accelerates quickly up to a low terminal velocity, then continues at constant velocity. At terminal speed, the downward force of gravity and the upward force of liquid resistance are in balance.
Will an object dropped on the moon reach a terminal velocity?
That varies, depending on the object. A massive object may take a long time to reach terminal velocity; a less massive object will reach terminal velocity faster. It basically depends on the object's mass, size, and shape.
If a liquid is thick and you drop an object in to it is the terminal velocity larger or smaller?
If a liquid is thick, the terminal velocity of an object dropped into it is typically smaller because the thicker liquid offers more resistance to the object's motion, slowing it down more quickly than a thinner liquid would.
If i dropped a penny off an airplane and it hits your head can it kill you?
I say NO. If you mean it is dropped and falls vertically. Discover Channel's "Myth Busters" tried to determine if a bullet would kill you if it was fired directly vertical and falls on its own. The bullet or penny would fall at terminal velocity which is about 120mph. However, they will tumble which slows them down more. This velocity and their mass is not enough to kill you.
When is terminal velocity good?
Based on two classes' worth of research on terminal velocity I'd say it's good for keeping some falling objects from reaching a speed that will, literally, be "terminal" (fatal) to whomever it hits. I was researching the myth behind whether or not a penny dropped off a tall building will kill some unlucky pedestrian below. All of my sources say it's impossible for said penny to do more than sting the person (barring them being hit in the eye or them somehow swallowing it), and the reason for this is terminal velocity.
Can an objects acceleration increase if you drop it from a higher altitude?
Yes, an object's acceleration remains constant regardless of the height from which it is dropped. However, the object will achieve a higher velocity when it lands after being dropped from a higher altitude due to its longer time in free fall.
What happens when an object is dropped from a helicopter?
When an object is dropped from a helicopter, it will fall due to gravity. Its speed and direction will be influenced by air resistance and any wind present. The object will accelerate until it reaches its terminal velocity, which is the maximum speed at which the air resistance equals the force of gravity.
