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.
