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 some equations for speed and velocity?
speed=distance/time. velocity=distance/time+direction.
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 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 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.
What is the speed of an object in a certain direction?
Speed is distance/time or distance per unit of time. It is velocity that is distance/time in a given direction. Velocity can be said to be speed in a certain direction.
What the relation between the time and the speed required to cover a fixed distance?
Speed is equal to distance divided by time. In physics there is a formula that shows the relation between time, distance and the speed. That v=d/t . Here v is velocity/speed d is the distance and t is the time
What is the Speed and how is it calcuated?
speed, or velocity= distance/time
What explains the difference between spped and velocity?
Distance covred in unit time is called speed
