Usually, speed just tells you how fast something is moving on average (total distance traveled divided by length of time), but the velocity also includes which direction it is traveling (usually by including the two or three dimensional position it was in when you start the measurement and end it) so we call it a vector.

When is speed equal to magnitude of velocity?
Speed is equal to the magnitude of velocity almost always. Speed is total distance / total time no matter which way the distance goes. Velocity is the distance from a starting point divided by total time.
How are acceleration and speed alike?
They are not alike but they are related. A positive acceleration means an increase in velocity (speed). A negative acceleration means a decrease in velocity. Velocity (speed) has the dimensions of distance / time. Acceleration has the dimensions of distance/time2 or velocity/time.
Is there a difference between meters per second and meters?
Yes. The first is a speed (or velocity), the second is a distance.
How can you determine the speed of an object that has constant motion if you have a distance vs time graph of the motion?
If constant motion means constant velocity then, total distance / total time = avg velocity => avg speed constant velocity => avg velocity = velocity
Total distance divided by total time?
total velocity * * * * * It is the average speed, not velocity which is a vector.
The distance between speed and velocity is that velocity includes?
Velocity includes direction. And it's the 'difference', not the 'distance'.
What is the difference between speed velocity acceleration?
Speed is the rate of change in distance, whereas velocity is speed and direction of travel. Acceleration is the change in velocity (including direction).
When does the speed of an object change?
An object's speed changes whenever the rate of change between the distance the object travels and the time it takes to travel that distance changes. Do not confuse speed with velocity; speed is scalar, and velocity is vector. Velocity can change when speed remains constant.
Does the speed of an object change?
An object's speed changes whenever the rate of change between the distance the object travels and the time it takes to travel that distance changes. Do not confuse speed with velocity; speed is scalar, and velocity is vector. Velocity can change when speed remains constant.
What are the differences between speed and velocity?
Speed is distance divided by the time taken Velocity is distance in a particular direction divided by the time taken. Velocity is a vector quantity while speed is a scalar quantity. That means that velocity include information about the direction of movement, while speed does not.
How would you differentiate between speed and velocity?
Speed is the magnitude of distance travelled per unit time, whereas velocity depends on the magnitude of distance travelled as well as the direction of motion. Speed is a scalar quantity, velocity is a vector. Speed cannot be negative, velocity can be negative. Average speed of an object after travelling a certain distance is always non-zero, but for velocity the average velocity can be zero (this follows from the previous idea).
What are some equations for speed and velocity?
speed=distance/time. velocity=distance/time+direction.
What is the Difference between velocity and average speed?
speed is a scalar quantity ie it has no directions...........whereas velocity is a vector quantity ie it has directions...................Also speed has distance n velocity has displacement
What are the similarities between speed and velocity?
-both have displacement - both quantities has speed - in both speed and velocity their is the distance traveled I do it for a science journal recuperation, i hope you understand.
What is the distance between mars and earth in mph?
There can be no sensible answer. "mph" is a unit for measuring speed or velocity, not distance.
What is he difference between speed and velocity?
http://wiki.answers.com/Q/The_difference_of_speed_and_velocity" The difference between speed and velocity is that speed is a scalar quantity(that have only magnitude) and velocity is a vector quantity(that have both magnitude and direction).
What the Formulae for velocity and speed?
You can get speed or velocity by dividing distance moved, by the time it takes to move that distance.
