Define density. Calculate the mass of a reservoir from its density. Compare and contrast the densities of various substances. Which weighs more, a ton of feathers or a ton of bricks? This old riddle plays with the distinction between mass and density.
There are two different non-metric tons, and you might encounter either one depending on context. There is a 'short ton', equal to 2000 lbs: about 907 kg. There is also a 'long ton' (also 'imperial ton' or 'displacement ton'), equal to 2240 lbs: about 1016 kg.
Use graphical methods to determine the acceleration of the cart. Determine the relationship between the cart’s acceleration and the net force applied to it. Determine the effect of the mass on the relationship between acceleration and force.
The rst experiment will test the linear relation between net force and acceleration by varying the force applied to a dynamics cart on a track and then measuring the resulting acceleration.
As explained earlier, the SI unit of force is the newton. Since F net = m a, 1 N = 1 kg · m/s 2. Although almost the entire world uses the newton for the unit of force, in the United States, the most familiar unit of force is the pound (lb), where 1 N = 0.225 lb. Thus, a 225-lb person weighs 1000 N.
21 Μαΐ 2024 · A gross ton is a unit of mass equal to 2,240 pounds (1,016 kilograms) used in the United States for large ships and merchant vessels. A metric ton is a unit of mass equal to 1,000 kilograms...
