... A stone of mass 750g is tied to the end of a string and spun. The string has a breaking strain of 35N and is 1.0m long. It is spun in a plane horizontal to the earth at a rate of 60 times a minute. i) What is the tangential velocity of the stone? ii) What is the centripetal acceleration of the stone ...

... Equation (8) is the rotational analogue of the momentum principle for translational motion: force = rate of change of momentum For single particles the angular-momentum equation offers no advantage over the momentum equation. However, it is invaluable in the treatment of systems of particles and, in ...

Definition of linear momentum
... Conservation of linear momentum - internal and external forces if we have a system composed of many particles the forces acting between the particles are internal ones. From Newton’s third law the vector sum of internal forces = 0 Forces acting from objects that are outside from the system are ext ...

... Weight is a measure of gravity’s force on a mass. F = ma. Your weight is your mass times gravity and is measured in Newtons (N). Where would you weight the most, Jupiter, Mars or Earth? Where would you weigh the least? Weight and mass and NOT about how much space is taken up. That is volume and it i ...
