Forces

Misconceptions

                     ( Mass and Weight are the same thing)

 

Well, not really.

Possible reason behind misconceptions:

" How much do you weigh?"," I weigh.. pounds". We use to the word weigh in our daily context to actually describe what should be 

known as " mass".  

* Weight is dependent on the force of gravity. The difference

in value between mass and weight is not very significant

on Earth because of the low value of force of gravity. It 

is more apparent on other planets.

​

Keys to correct misunderstanding:

* Show that weight and mass have different units.

* Show that weight is a vector, and mass is a scalar.

* Use the following links as a guide.

                    ( Mass and Inertia are the same thing)

                                                                   

Possible reasons behind misconceptions:

They are extremely related; but not quite the same! Both are related

to the how much matter is in an object.

(The larger object must exert the larger force in Newton`s Third Law)

 

That is what you would think right? But not quite, Newton`s Third Law says that they produce EQUAL and OPPOSITE forces on one another, regardless of size.
