A line with mass - a metal rod of mass $X$, with a scale at each end. As the rod is vertical the scale at the bottom will read the full mass, as the rod reclines to horizontal each scale will read ...
If a cart hits a wall, does the weight of it affect how it moves, when the center of gravity is constant?
I have a model that represents a bicycle (a wood block with wheels), and I'm balancing the center of gravity so it's the same as a real bike. However, when the center of mass is kept constant, does ...
I don't want to go to science world to find out because it would be a long round-trip. I understand that acceleration/deceleration would effect the weight and I can also imagine that someone at ...
An object is falling and it weighs 25 kg (on a scale, presumably). What is its mass? I know that weight is measured in Newtons and mass in kilograms, but what if a problem states that something ...
My science teacher is always saying the words "weight of an object" and "mass of an object," but then my physics book (that I read on my own) tells me completely different definitions from the way ...
