Finding the final velocity is simple, with a few calculations and basic conceptual knowledge. Determine the object’s original velocity by dividing the time it took for the object to travel a given distance by the total distance. In the equation V = d/t, V is the velocity, d is the distance, and t is the time.

- Difference Between Speed and Velocity
To find an object’s velocity, first calculate its speed and then indicate the direction of its movement! In this physical science worksheet, students will review how to calculate velocity given time and distance and then apply this process to several diverse word problems.
Transcript. Rate of change in position, or speed, is equal to distance traveled divided by time. To solve for time, divide the distance traveled by the rate. For example, if Cole drives his car 45 km per hour and travels a total of 225 km, then he traveled for 225/45 = 5 hours. Created by Sal Khan.
In this formula, v a v g is the average velocity; Δ x is the change in position, or displacement; and x f and x 0 are the final and beginning positions at times t f and t 0 , respectively. If the starting time t 0 is taken to be zero, then the average velocity is written as below: v a v g = Δ x t.
A physicist would measure your velocity as the "limit for a period of time", zero, to get the instantaneous velocity. Changing Your Velocity.
Velocity refers to both the speed of an object and the direction of its motion. A velocity value should have both speed units and direction units such as: m/sec north ; km/h south; cm/s left; km/min down
Velocity describes how position changes; acceleration describes how velocity changes. Two layers of change! What does acceleration mean? Compared to displacement and velocity, acceleration is like the angry, fire-breathing dragon of motion variables. It can be violent; some people are scared of it; and if it's big, it forces you to take notice.
