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.
Speed takes no notice of the direction of the motion.Velocity means the speed and its direction.
When the speed (of falling) is increased, the force of gravitation will be the same, but the air resistance will increase. At some speed, the two will be in balance - there will be no more acceleration, and the object is said to have achieved terminal velocity.
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.
Terminal velocity is not a predetermined speed. Terminal velocity is the condition in which the forces of gravity and drag are equalized, and no further change in speed is possible if these conditions remain the same. However, terminal velocity can vary greatly depending upon altitude, wind resistance of an object, atmospheric conditions, and other factors.
Gravity. The object starts at zero velocity, and gravity always pulls the same. Drag, however, increases when velocity increases. Terminal velocity is when gravity has accelerated the object to the speed where drag is the same as gravity.
Well velocity is mass * acceleration, so if you add weight while keeping the same speed, that would be a change in velocity.
Speed and velocity always have the same magnitude, becausespeed is the magnitude of velocity.The difference is that velocity has a direction but speed doesn't
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
They will fall at the same speed once they reach terminal velocity.
No, they are not the same! Velocity involves the speed and the direction of the moving object...
No. An object's terminal velocity depends on how much air it must push aside while it falls, and if there were no air, there would be no such thing as terminal velocity. In air, different objects have different terminal velocities, depending on their weight and shape. All of this is the main reason that parachutes are popular for activities where falling is involved.
same speed , coz velocity is constant velocity consists of speed and direction...
velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.
One example of Velocity is that if you are running in the same direction, your speed and velocity is the same. But if you are running AROUND the track, your speed is the same but your velocity is changing.
Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.
I used to do a bit of parachuting back in the 70s and terminal velocity was always reckoned to be about 120 mph (200 kph) achieved after about 12 seconds in free fall. But different objects will have different TVs, depending upon how aerodynamic they are. In physics, When an object is in a freefall, and it reaches its terminal speed, there is no net force, and so its acceleration is zero. Going down, the direction of the air resistance is downwards, whereas that of the weight is upwards. Going up, air resistance R and weight W are in the same direction. i.e. downwards. By F=ma, When an object is thrown vertically upwards, at the instant its speed equals this terminal speed on the way up, the magnitude of its acceleration is 20ms-2. the direction is downwards. then by v = u + at, you can easily calculate the terminal velocity in many different cases.
No. Velocity is the combination of a speed and its direction. In order fortwo objects to have the same velocity, they must be moving at the samespeed, and in the same direction.
Terminal velocity is the velocity of a falling object once it has become constant, so they are the same thing.
Air resistance doesn't change with weight. It changes with speed and shape. More speed, more air resistance. If the shape has a lot of surface are to drag the air, it is more resistant, but this factor does not change with weight or speed. This is why terminal velocity is possible. As the object falls, its speed increases, so its resistance increases also, because resistance depends directly on speed. But as this resistance is increasing, the gravity is staying the same. So, eventually, resistance catches up with gravity and cancels it out, causing an end to acceleration, or constant speed.
In common speech, velocity means speed, they are the same thing.
No. Speed is the magnitude of velocity and acceleration is the change of velocity in time.
No. Speed tells the size of velocity, but velocityalso includes the direction of the motion.
Critical Velocity has the same dimensions as of velocity & terminal velocity. [L/T]
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).
Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.
