Use the units given in the table below to determine whether the formulas are dimensionally consistent.
/ this symbol (to the left) means divided by
Length= distance= m
area= m squared
acceleration= m/s squared (only the s is squared)
force= Kg m/s squared (only the s is squared)
energy= Kg m squared /s squared
power= Kg m squared /s cubed
How do you solve these and how do you multiply the units?
Does energy= (mass) (acceleration) (length)
Does speed= acceleration/time
Does area= (length) (length)
Does energy= (mass) (speed squared)
Does energy= (mass) (acceleration)/length
The Attempt at a Solution
I tried the first one.
energy= (mass) (acceleration) (length)
= [Kg] [m/s squared] [m]
= [Kg m squared /s]
Is that right?
