    Q on basic principles of weight and mass

    :smile::smile::smile: That's too funny..! Goes to prove when phrasing a question, there is no such thing as too much clarification :rolleyes:

    Q on basic principles of weight and mass

    Sir, I thank you..! That one line solves the flame war - the act of weighing it gave me it's mass (not it's weight LOL) So I was right in what I was saying, but I was using the wrong terms. So on Earth, weighing scale are calibrated to give the mass of the object placed on them. And...

    Q on basic principles of weight and mass

    Thank you for the quick reply. So, if I wanted to calculate the energy of a potato traveling at a certain speed... If I weighed the potato and found it to be 500 grammes and it was doing 10 m/s Would the equation be e=(0.5*10^2)/2 or e=((0.5*9.81^2)*10^2)/2 I though it was the first...

    Q on basic principles of weight and mass

    Hi Newbie here so please go easy on me..! To keep this within my ability to understand can we please live in the perfect world of the junior physics class i.e. uniform density, no friction g=10 etc - thanks I understand that 'weight' is mass x g So the weight of something is how hard...

    Newbie Asks: Can I Discuss Recoil and Impact Here?

    Newbie saying Hello and an unusual question... Just thought I'd say Hi and ask if I can post a rather odd question. I've not done any academic physics since leaving school at 18 (I'm a Brit) but think that knowing the basics makes life a whole lot easier. Physics stops your shelves...
