... SI system: In the SI system of units, mass is a base unit and weight is a derived unit. Typically, mass is specified in kilograms (kg), and weight is calculated from W = mg. If the gravitational acceleration (g) is specified in units of m/s2, then the weight is expressed in newtons (N). On the earth ...

... force required to keep the bag moving in a circle and balance a component of the force of gravity. At the equilibrium point, the tension is greatest because the speed is greatest and the gravity component is the full gravity force. At the extremes, the speed is zero, so there is no centripetal force ...

... we can use energy to solve this one. In that case we need to catalog our energy before and after the slope. Before, the height is zero and so is the potential energy. The linear kinetic energy is simply 12 mv 2 . We are not given the mass, but we are used to that cancelling out in these energy probl ...

... Method #1: Select a series of masses that give a usable range of displacements. The smallest mass must be much greater than the mass of the spring to fulfill the massless spring assumption. The largest mass should not pull the spring past its elastic limit (about 60 cm). Beyond that point you will d ...
