What is Terminal Velocity?
The terminal velocity is the fastest velocity that an object can have as it is falling.
1 of 10
When does an object reach terminal velocity?
At some speed, the drag or force of resistance will equal the gravitational pull on the object.At this point the object ceases to accelerate and continues falling at a constant speed called terminal velocity (also called settling velocity).

What factors affect the terminal velocity of an object?
Terminal velocity depends upon how much air resistance there is versus weight. Air resistance is controlled by the surface area over which the air acts (called a cross section) and speed. A body's shape in the direction of fall is very important

What is the cause of terminal velocity?
As the object falls, the force of gravity initially causes it to continuously speed up, as it gets faster and faster, the air drag force increases until eventually, the air drag force is exactly equal to the force of gravity
