Velocity is defined as a vector measurement of the rate and direction of motion or, in simpler terms, the rate and direction of the change in the position of an object. The scalar (absolute value) magnitude of the velocity vector is the speed of the motion. In calculus terms, velocity is the first derivative of position with respect to time.

Velocity is the rate of motion in a specific direction. I'm going that-a-way at 30 kilometers per hour. My velocity is 30 kilometers per hour that-a-way. Average speed is described as a measure of distance divided by time. Velocity can be constant, or it can change (acceleration). Speed with a direction is velocity.

A physicist would measure your velocity as the limit for a period of time, zero, to get the instantaneous velocity. Changing Your Velocity When velocity is changing, the word acceleration is used. Acceleration is also a vector. You speed up if the acceleration and velocity point in the same direction. You slow down (also referred to as decelerating) if the acceleration and velocity point in opposite directions. When you accelerate or decelerate, you change your velocity by a specific amount over a specific amount of time.

where. 1  r is the rate, or speed (sometimes denoted as v, for velocity, as in this kinematics article) 2  d is the distance moved. 3  t is the time it takes to complete the movement.

Remember: 1  Speed is a scalar quantity that indicates rate of motion distance per time. 2  Velocity is a vector quantity that indicates distance per time and direction. 3  Acceleration is a vector quantity that indicates the rate of change of velocity.

Velocity is a vector quantity that indicates distance per time and direction. Like speed, its units are length/time, but direction is also cited. Acceleration is a vector quantity that indicates the rate of change of velocity. It has dimensions of length/time2.

Velocity Definition. Velocity is defined as a vector measurement of the rate and direction of motion or, in other terms, the rate and direction of the change in the position of an object. The scalar (absolute value) magnitude of the velocity vector is the speed of the motion. In calculus terms, velocity is the first derivative of position with respect to time. How Is Velocity Calculated? The most common way to calculate the constant velocity of an object moving in a straight line is with the formula:

Velocity, Speed, and Motion... Oh My! Velocity and speed are very similar ideas, but velocity is a vector, and speed is not. Suppose we knew that someone was driving at thirty-five kilometers an hour (35 km/hr), but the direction wasn't given.
