Is constant velocity and terminal velocity the same?
Yes, but only in free-fall. If I'm driving at 60 mph, I have a constant velocity, but it's not my "terminal velocity" in the sense that there is no limit to my acceleration caused by air friction. But yes, an object in free-fall reaches its terminal velocity when its velocity stops increasing (acceleration=0).
Is terminal velocity the constant velocity of a falling object when the force of air resistance equals the force of gravity?
Terminal velocity is the velocity of a falling object once it has become constant, so they are the same thing.
Terminal velocity is the constant maximum velocity reached by a body falling through the atmosphere under the attraction of gravity. An object is moving at its terminal velocity if its speed is constant due to the restraining force exerted by the air, water, or other fluid through which it is moving.
If the velocity is constant (i.e., there is no acceleration). Terminal velocity is an example, although any constant velocity would fit this description.
Terminal velocity is the velocity that a falling object approaches asymptotically as it falls through a resisting medium (like air). If an object impacts something before getting close to the terminal velocity it will still have an "ending velocity" but it won't be the same as the terminal velocity. If an object falls far enough, the ending velocity will approach the terminal velocity close enough for them to be essentially the same.
The terminal velocity of a falling object is the constant speed where the force of gravity is equal to the force of drag. Then the forces cancel each other out. Essentially, terminal velocity is when the speed of a falling object is no longer changing. It isn't accelerating or slowing. It's constant.
An object that has reached its terminal velocity is going at a constant velocity. Acceleration is the rate of change of the velocity. The rate of change is zero. Therefore, the acceleration is zero.
An object falling at terminal velocity is moving at constant speed (that's what terminal velocity means) and we will assume it is not changing direction (i.e. it is falling straight down; in reality it is more likely to be bobbing and weaving on the wind.) Constant speed and direction is another way of saying constant velocity. when an object is acted upon by a net force, it's velocity changes. So, since we know that the… Read More
What is the constant velocity at which a falling object is balanced by the force of gravity and the force of air resistance?
Any skydiver can fall at a constant velocity. This is called the, "Terminal velocity". Since we do not have the picture that you mention, nothing more can be assumed.
Terminal velocity is the velocity at which a falling body reaches constant velocity due to air resistance.
If you are talking about free fall, acceleration due to gravity and velocity will both be negative, until terminal velocity is reached, at which point the falling object is no longer accelerating and has constant negative velocity.
The constant velocity of a falling object when the force of air resistance equals the force of gravity?
What you are describing is called the "terminal velocity".
At terminal velocity (constant velocity), the acceleration is zero, but prior to that, there is a downward acceleration.
It is when the total air in the egg is the same as the friction created by the shell. That is when it has created terminal velocity
constant velocity means the speed and direction are the same.
Gravitational pull is constant...but is limited in a atmosphere due to wind resistance (terminal velocity).
When objects reach terminal velocity what are the forces involved and describe the velocity of the object?
When an object is at terminal velocity, the two forces due to gravity and drag are equal, so the object ceases accelerating. Its motion is constant and vertically downward.
Yes, if it reaches terminal velocity, which is a constant velocity. When terminal velocity is reached, the downward gravitational force is equal to the upward force of air resistance, and the object no longer accelerates.
i believe you are referring to terminal velocity
When an object moves with constant velocity does its average velocity during a time interval differ from its instantaneous velocity at any instant?
No. If it its moving at constant velocity, its instantaneous velocity would be the same as its constant velocity.
Terminal velocity defines the point at which an object will no longer accelerate. When a falling object reaches terminal velocity, it will continue to fall at a constant speed.
Terminal velocity, where the driving force = drag force from the water
Speed takes no notice of the direction of the motion. Velocity means the speed and its direction.
Technically, its false.... Terminal Velocity is defined as "the constant maximum velocity reached by an object falling through the atmosphere under the attraction of gravity". The crash is simple a result of and the conclusion to the fall....
Terminal velocity is the velocity where the force of gravity balances the drag of the air stream flow past the object. At terminal velocity, the object's acceleration due to gravity becomes zero, and the object begins to fall at a constant velocity. In a vacuum, however, there is no air - and thus no drag- so the object continues to accelerate.
It cannot go any faster. It's acceleration drops to 0 and the velocity stays constant.
When the upward force of air resistance matches the downward pull of gravity and the object falls with a constant velocity?
It's called the terminal velocity.
Terminal velocity. When the parachutes cannot fall any faster.
What is the constant speed of an object reached when the force of gravity is balanced by air resistance?
A skydiver steps from a helicopter and falls for 5 seconds before reaching her terminal velocity During this 5 second interval her acceleration will?
increase- your speed will increase until terminal velocity is reached. From there it will stay constant.
The difference between free fall and terminal velocity i that free fall is when an object is falling or descending through the air with little air resistance or drag. Terminal Velocity, on the other hand is when the resistance of air and the force of gravity balance each other out causing the object to reach a constant velocity. .
Yes, if the instantanious velocity is constant.
Yes. An object moving in a straight line at constant speed has constant velocity.
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.
Terminal velocity if it has reached its top speed. Or obviously constant speed.
It stops accelerating, and falls the rest of the way at constant speed.
They reach their terminal velocity.
Net force and so net acceleration becomes zero and so the velocity becomes constant ie uniform.
constant slope. really anything will work as long as it stays the same. so if your line is straight then you have a constant velocity. :)
That is not true. When speed (or velocity, which is the same as speed but with direction) is constant, the acceleration is 0
newton's first law states: an object will remain at rest or at a constant velocity unless the forces on it become unbalanced. As the forces on the object are now balanced it falls at a constant velocity. For falling objects this is called the terminal velocity
Both are same.
The velocity stays the same, it is constant
If the velocity is constant there is no acceleration. Speed is not velocity, velocity has speed and direction. I A car going around a circular track at 60 mph keeps the same speed but changes direction and thus accelerates at a constant speed. Velocity is speed in a certain direction. So change the speed but keep direction the same and you change the velocity. or Change the direction while keeping the speed the same and… Read More
Critical Velocity has the same dimensions as of velocity & terminal velocity. [L/T]
Which term refers to the speed at a falling object stops accelerating and begins to fall at a constant rate?
When the force of gravity equals the force of air resistance an object falls at a constant rate is called what?
The parachutist will no longer accelerate. They will just glide with constant velocity and enjoy the scenery.
Only if the velocity is constant.
