(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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

mass= Kg

time= s

area= m squared

speed= m/s

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

2. Relevant equations

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

3. 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?
