While you cannot physically square your velocity, such as you are traveling at 10 meters per second, and then there's another dimension where you are 100 meters squared per second squared, velocity squared comes up in various physics calculations. Kinetic energy of an object in motion is (1/2)*mass*(velocity squared). This just means that you take the velocity and square the number, and also square the units, so (10 m/s)2 = 100 m2 / s2 for the calculation.

What is root mean square velocity?
For an object moving at a variable velocity you:calculate the square of the velocityfind its mean valuecalculate its square root.If the velocity is constant then the RMS velocity has the same value.
What is the formula for calculating root mean square velocity?
VRMS = 1/N times square root of [ sum(Vn2) ]
How do you find time from the formula Velocity equals initial velocity plus gravity times time squared?
vf=vi+at² simplifying making vi=0, v=at²t²=v/at=√v/atime equals square root of velocity divided by acceleration (or gravity)
The x and y component of a billiard balls velocity are 5 m s and 4 m s respectively What is the actual velocity of the billiard ball?
Using the Pythagorean theorem, we can determine the actual velocity in the xy plane to be (the square root of 41) m/s along the vector [5,4].
Square the input and then multiply it by 16 Add this product to the initial velocity multiplied by the input?
i dont know i thought you guys figured it out

What is the meaning of root mean square velocity?
Root mean square velocity is the measure of the velocity of gas particles that is used for solving problems. It is the square root of the average velocity-squared of the molecules in a gas. The formula for root mean square velocity is sqrt(3RT/Mm) where Mm is the molar mass of the gas in kg / mole, R is the gas constant, and T is the temperature in kelvin.
Why average velocity of molecules in gas zero whereas the average square of velocity is not zero?
Because squaring a velocity removes its sign. A velocity may be negative, but it's square is always positive. If two velocities are +5 and -5, their average is zero. But both squares are +25, so the average square is +25.
What happends to kinetic energy when the velocity increases?
Kinetic energy is proportional to the square of the magnitude of velocity.
Why average velocity of molecules of a gas is zero but the square of average velocity is not zero?
It depends on the sign of velocities. For example, if there are two velocities 7 and -7 m/s then the average velocity of the molecules will be 0. But, the square will be 49. The general thing here is that even if a velocity is negative, the square of EVERY velocity irrespective of the sign is positive i.e., squaring always removes the negative sign.
What will be the velocity of a satellite which is revolving around the earth in a circular orbit the radius R if the radius is increased from R to RR what will be the velocity?
the velocity will be velocity divided by square root of 2
What is the 4th equation of motion?
displacement = (final velocity square + initial velocity sq. )/ 2 * acceleration
What is the relationship between centripetal force and velocity?
Centripetal force is = mass * velocity square divided by radius
What is the difference between escape velocity and orbital velocity?
Escape velocity is the velocity that an object needs in order to reach infinite distance, wherein the force will equal to zero. Orbital velocity is the velocity of an object so it can stay in orbit.
What is the velocity of an object that has the kinetic energy of square root of 3 and the mass of 5?
The object's velocity is approximately 0.83m/s
How do you solve the time by the given of mass and kinetic energy?
Kinetic energy is equal to one-half of the product of an object's mass and the square of its velocity. Velocity is change in displacement divided by time. If you have the kinetic energy and mass, you can calculate the velocity by taking the square root of the quotient of kinetic energy and mass, and thereby solving for the velocity.
What is molecular velocity in chem?
Molecular velocity is defined as the velocity of a each molecule in a certain sample of gas. It can be expressed by means of root-mean-square velocity, average velocity and most probable velocity.
