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 s a system that defines the zero point of the variable what if your studying?
instantaneous velocity
Why mass is variable in E mc 2?
It is not a variable. The equation says that the energy contained in any given mass is equivalent to the mass times the velocity of light squared.
How do you work out velocity when given acceleration and time?
Answer: v=u + at v (Velocity) = u (Starting velocity) + a (acceleration) x t (time) So, starting from stationary (u=0), the velocity is simply a x t e.g. if the acceleration is 5mph per second per second, after 10 seconds you would be travelling at 50mph. Answer: The above is for constant acceleration. In the case of variable acceleration, integration has to be used.
In position vs. time graph what variable does slope represent?
The slope of a line on a position vs. time graph would represent the a velocity of the object being described.
What is the difference between uniform and variable velocity?
Uniform velocity is velocity unaffected by acceleration. Variable velocity is velocity affected by acceleration. Lauren "Physics above all!"
What is varaible velocity?
Non uniform velocity is known as variable velocity.
What is the difference between constant velocity and variable velocity?
Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.
What does the word independent means in science?
Independent means that it is a variable that is unaffected by other variables. For example, in terms of acceleration, velocity is the dependent variable, and time is the independent variable. Velocity is dependent upon time, but time is not dependent upon velocity. Of course, technically speaking, this is only for nonrelativistic scenarios. If velocity is extreme (near the speed of light) time IS affected by velocity in spacetime. But, that's a different issue.
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 condition in which a body moving with uniform speed has a variable velocity?
Speed is considered a scalar while velocity is refered to as a vector. A vector can be varied with respect to its direction. Therefore, constant speed while changing direction varies the velocity
Is it possible to have a constant mass and variable velocity?
Yes it happens all the time. Any force will change the velocity but will not affect the mass.
Can an object have constant velocity and but variable speed?
No. Velocity has two parts, speed and direction A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.
The velocity of sound in air is independent of change in what variable?
The velocity of sound in air is independent of change of the atmospheric pressure, but is really dependent on the temperature.
What s a system that defines the zero point of the variable what if your studying?
instantaneous velocity
What veritables determine how fast an object will be moving when it reaches terminal velocity?
The surface area is the variable to determine how fast an object will be moving when it reaches terminal velocity.
Which variable is directly proportional to frequency?
Frequency, when referring to waves, is directly proportional to the velocity of the wave. Frequency in inversely proportional to the wavelength.
