Velocity, on the other hand, is your speed and direction. It is a vector because it does have a direction. For example, 3 miles per hour is a speed, but 3 miles per hour south is a velocity. Since an object moving in a circle is constantly changing direction, its velocity is constantly changing.
Dec 02, 2019 · Newton realized that when the ball is propelled at a certain, magic velocity, it will never fall. At this velocity, the ball will trace the linear surface; basically, it travels horizontally, but never vertically, because as soon as it falls, the Earth beneath it curves: the ball falls at the same rate as the Earth curves.

Terminal velocity, steady speed achieved by an object freely falling through a gas or liquid. A typical terminal velocity for a parachutist who delays opening the chute is about 150 miles (240 kilometres) per hour. Raindrops fall at a much lower terminal velocity, and a mist of tiny oil droplets settles at an exceedingly small terminal velocity.
The velocity/speed of an moving object can be determined by using the following formula: where v is the velocity/speed, ...
ferential equations describing the velocity of a falling object that we just considered above were ﬁrstorder. In the related secondorderequation, y00= g, the unknown function represented by the variable y is the distance the object has fallen. The velocity would be v = y0. Including air resistance, we get y00= g k(y0)2/m, another secondorderequation.
Dec 14, 2011 · We discussed velocity, a vector, and speed, a scalar. If we are considering instantaneous velocity, then speed is the magnitude of velocity. Our last quantity, acceleration, can also be discussed in terms of a vector acceleration or simply the magnitude, but for acceleration we have no special term for the magnitude.
