In a vaccum, different objects have no terminal velocity... the further they fall, the faster they go. So, "air drag" is what provides differing terminal velocities, and the object's shape and weight distribution controls that drag.
An object in free fall is only experiencing one force downward, the force due to gravity (F=mg).
However, there is an additional force "pushing up" on the object. This is due to the resistance the air exerts on the object, also known as drag force. The equations involved are far more complex than F=ma. Imagine the same concept of wind filling up the sails of a kite.
When the force due to air resistance equals the gravitational force, the forces are balanced, and the object has reached terminal velocity.
For an object in freefall, terminal velocity is reached when the drag force becomes equal and opposite to the force of gravity. This creates a net force of 0, resulting in no further acceleration.
On any planet with an atmosphere, gravity is counteracted by the force of air friction with the object that is falling. This is known as terminal velocity - the point at which the forces of air resistance and gravity balance.
balanced
Balanced forces do not bring about any change in motion. If forces are balanced, an object is either at rest, or moving in a straight line at constant velocity.
yes there is? i hope i hepled. :)
Not balanced UNTIL it reaches terminal velocity.
terminal velocity
When terminal velocity is reached, the gravitational force is balanced with the force of resistance.
Terminal velocity is an example of balanced forced because the gravitational forces and the air resistance balance each other.
... I think you want to know about forces. At terminal velocity, the force of gravity is balanced by the air resistance, so no further acceleration occurs (balanced forces are the equivalent of an absence of force), which is why we call it *terminal* ("end value") velocity.
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
Terminal Velocity.
In that case, the object is said to have achieved terminal speed.
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.
If the penny is in a vaccum, the penny has no terminal velocity because verminal velocity is when the resistance against the falling penny is equal to the force of gravity. So if it is in a vaccum, it has no forces resisting the fall, and it has no terminal velocity.

When an object is falling, it accelerates, so it is speeding up. The faster it goes, the more air resistance there is on the object. Eventually, the force of the air resistance pushing up on the object will equal the force of gravity pushing down on the object. The forces on the object are balanced (they cancel out), so it will have no acceleration. This causes terminal velocity; the object is not speeding up anymore. When the forces on an object are balanced, it has no acceleration. This does not mean it has no velocity, it just means that the velocity is not changing (it does not speed up or slow down.)
