An object falling through space by the force of gravity reaches a terminal velocity speed of:_____.
1 answer:
An object falling through space by the force of gravity reaches a terminal velocity speed of 9.8m/
Terminal velocity Near the surface of the Earth, any object falling freely will have an acceleration of about 9.8 metres per second squared (m/s2).
What is Terminal Velocity?
Terminal velocity is the maximum velocity (speed) attainable by an object as it falls through a fluid (air is the most common example).
It occurs when the sum of the drag force (Fd) and the buoyancy is equal to the downward force of gravity (FG) acting on the object.
Since the net force on the object is zero, the object has zero acceleration.
At terminal velocity, the object moves at a steady speed in a constant direction because the resultant force acting on it is zero.
In fluid dynamics an object is moving at its terminal velocity if its speed is constant due to the restraining force exerted by the fluid through which it is moving.
