Terminal velocity is the maximum velocity an object reaches when it is falling under the force of gravity or another constant driving force. The object is subject to a resistance that increases as the velocity increases,... More »

The basic formula for velocity is v = d / t, where v is velocity, d is displacement and t is the change in time. Velocity measures the speed an object is traveling in a given direction. More »

Speed and velocity are similar in that they are measured in the same measurement units, which are meters per second. However, velocity and speed are very different quantities because one has a direction and the other one... More »

Objects fall at the same velocity regardless of their weight, if gravity is the only force acting upon them. In a vacuum, where air resistance has been eliminated, a bowling ball and a feather fall at the same speed. More »

Terminal speed, also known as terminal velocity, is the maximum speed of a falling object when it can no longer accelerate from the gravitational pull or any constant force. This is due to air resistance negating the for... More »

Terminal velocity is the velocity at which an object in freefall no longer accelerates due to gravity because the drag force of the surrounding air equals the gravitational force of Earth. Objects with more mass have mor... More »

It is possible for an object to be accelerating if it has a zero speed or zero velocity. In such a case, the object only has zero speed for an instant. More »
