**INTRODUCTION**

The velocity calculator is used to compute the value of velocity. The Calculator has equation for calculating velocity and items related to velocity

**APPLICATION**

The calculator is useful for different users in the world from scientists to the students. It can be used to compute the velocity of a car, revolution of earth around the sun among others. Students can also use the calculator to compute the velocities of different objects.

**DESCRIPTION**

Velocity refers to the distance travelled by it in unit time in a given direction, the difference between the final and initial position of an object. Velocity is equivalent to a specification of its speed and direction of motion, e.g. 60 km/h to the north. Velocity is an important concept in kinematics, the branch of classical mechanics which describes the motion of bodies.

Velocity is a vector physical quantity; both magnitude and direction are required to define it. The scalar absolute value (magnitude) of velocity is called "speed", a quantity that is measured in metres per second (m/s or m·s−1) in the SI (metric) system. For example, "5 metres per second" is a scalar (not a vector), whereas "5 metres per second east" is a vector. If there is a change in speed, direction, or both, then the object has a changing velocity and is said to be undergoing an acceleration.

Velocity - The velocity of a moving particle is the distance travelled by it in unit time in a given direction, or in other words, velocity is the rate of displacement of a body.

Final Velocity - based on initial velocity, constant acceleration, and time traveled.

final velocity of an object equals initial velocity (Vf) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v.

Kinetic Energy -Kinetic energy is directly proportional to the mass of the object and to the square of its velocity:

**K.E. = 1/2 m v2**

Momentum - The mass of an object is m and it has a velocity v, then the momentum of the object is defined to be its mass multiplied by its velocity. Momentum has both magnitude and direction and thus is a vector quantity. The units of momentum are kg m s−1 or newton seconds, N s.

**momentum = mass (velocity)**

Terminal Velocity - steady speed achieved by an object freely falling through a gas or liquid.

maximum velocity in free fall with drag.

Escape Velocity- s referred to as the minimum velocity needed by anybody or object to be projected to overcome the gravitational pull of the planet earth.

In other words, the minimum velocity that one requires to escape the gravitational field is escape velocity.

Distance Traveled - based on constant velocity and time

**s = velocity x time**

Distance Traveled - based on initial position, initial velocity, constant acceleration and time of travel

**s=v _{i}t+1/2at^{2}**
