Distance between speed and velocity?
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.
If A student measures the speed of a rolling ball three times. She adds the measurements and divides by 3. What quantity did the student calculate?
She obtained the average speed of the three measurements.
What is the average speed after three minutes?
Probably over 9000.
What is the average speed if you ran 3 miles 45 minutes?
Three miles in 45 minutes is an average speed of 4 miles per hour or 5.87 feet per second.
What are three components needed to find an object acceleration?
Using the definition of acceleration as change of speed / time, you basically need to know: * A time interval during which the object accelerates. * The velocity at the beginning of this time interval. * The velocity at the end of this time interval.

Why it is facts about speed and velocity?
three facts about speed and velocity
Is it speed acceleration velocity when a softball is hit into the outfield?
In that case, you have all three - speed, acceleration, velocity.
What is the average speed of electricity?
There are three different speeds here.The average speed of electrons - whether there is a current or not - is a significant fraction of the speed of light. That speed depends on the temperature. (The average VELOCITY of course is zero if there is no current, since as many electrons will go in one direction as in another.) The drift velocity (the average velocity) of the electrons is a small fraction of a millimeter per second. The exact value depends on the current, the cross section, and the material. The speed at which a signal can propagate in copper is about 2/3 of the speed of light in a vacuum - so, about 200,000 km/second. It is this speed that makes your light react quickly when you activate a switch.
When an object's speed change does its velocity change?
Since speed is the magnitude component of the vector quantity of velocity, of course when speed changes velocity also changes. Speed is a one dimensional scalar quantity. Velocity is a three dimensional vector quantity describing both speed and direction of motion.
What are three ways that an object can be changed by a force?
by direction, speed and velocity i believe

What three things must you know to determine velocity?
Just speed & direction.
Distance between speed and velocity?
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.
How many types of velocity?
Velocity can either increase or decrease. It can do so at either an increasing or decreasing rate (positive or negative acceleration)
How do you calculate velocity?
given distance- 200km time-5 hours speed- distance/time 200/5 40km/hr Divide distance by time for speed Divide speed by distance for time Multiply speed and time for distance Those are three ways to make sure you have it right Average Velocity = (change in position) / (elapsed time) Instantaneous Velocity = [limit as elapsed time approaches 0] (change in position) / (elapsed time) Velocity is measured in m/s+ direction
If the speed of a moving object triples then what else increasses by a factor of three or more?
velocity by 3xmomentum by 3xenergy by 9x
