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.
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.
The forces are balanced because they are falling at a constant speed. According to Newtons first law of motion an object will keep moving unless an unbalanced or net force acts upon it. If we may step in here for the novel purpose of answering the question . . . The balanced forces on an object that is falling with constant speed are typically the force of gravity (the object's 'weight') and the equal and opposite force of air resistance.
Drag (air resistance). When a falling object reaches terminal velocity (continues to fall at a constant speed, but acceleration stops), the force of drag and the force of gravity are equal, but opposite in direction.
balanced
Not balanced UNTIL it reaches terminal velocity.
When an object is falling at terminal velocity, the forces of gravity pulling it downward and air resistance pushing upward are balanced. This results in a constant velocity for the object as it falls.
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.
Terminal velocities are balanced forces. At terminal velocity, the upward force of air resistance acting on an object falling through the air is equal in magnitude to the downward force of gravity, resulting in an equilibrium where the object falls at a constant speed.
... 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.
No, a skydiver's acceleration remains constant as they fall towards their terminal velocity. This is because terminal velocity is the point at which the forces of gravity and air resistance are balanced, resulting in a constant 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
When the upward and downward forces on a falling object are equal, the object reaches terminal velocity. At terminal velocity, the object stops accelerating and falls at a constant speed.
In that case, the object is said to have achieved terminal speed.
