What else can I help you with?
Why is the terminal velocity in water less than the terminal velocity in air?
More resistance, caused by a greater density.
How would the terminal velocity of an object falling towards earth differ than the terminal velocity of the same object falling through water?
because water has higher viscosity than air so resisting the movement of the body in it more than air so decreasing the velocity
What is it called when air resistance and gravity are the same?
When air resistance and gravity are equal, it is known as terminal velocity. At terminal velocity, an object falling through the air no longer accelerates but rather falls at a constant speed due to the balance between air resistance and gravity.
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.
Does terminal speed and terminal velocity are 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).
How does air resistance affect terminal velocity?
Air resistance increases as an object's speed increases. At terminal velocity, the upward force of air resistance equals the downward force of gravity, resulting in a constant velocity. The greater the air resistance, the lower the terminal velocity of an object falling through the air.
What is the speed an on object reaches when the force of gravity is balanced by air resistance called?
terminal velocity
Should the terminal velocity of two different size spheres be the same?
No, the terminal velocity of two different size spheres will not be the same. Terminal velocity is influenced by the size, shape, and weight of an object. Larger spheres are likely to reach a higher terminal velocity than smaller ones due to differences in air resistance.
If a 75 kg person and a 200 kg crate were launched out of a plane at the same time which one would reach terminal velocity first?
As Galileo demonstrated, acceleration is independent of mass, therefore, they would reach terminal velocity at the same time. This is, of course, ignoring air friction.
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.
When gravitational forces and air resistance equalize on an object that is falling toward earth and the object stops accelerating its velocity is called?
In that case, the object is said to have achieved terminal speed.
Is terminal velocity a type of friction?
No. Terminal velocity is a particular kind of velocity and friction is a particular kind of force. The terminal velocity of a falling object is the maximum velocity it can have because air resistance prevents it from going any faster. And air resistance is a type of friction. So terminal velocity is due to a type of friction.
