On a force table, a thread has a brass cylinder attached to it weighing 100 grams. Earth's gravity pulls this weight (0.1 kg) downward with 0.98 N of force, and therefor the same amount of weight is applied to the cylinder (0.98). However, a. Why isn't the cylinder falling to the floor? b. Why is the cylinder not rising to hit the pulley? c. How strongly do you think the thread's loop is pulling upward?
Two objects are in Free Fall, so both objects can be considered weightless. Object A has a much smaller mass than Object B. An equal force is applied to both objects.A. Object A will accelerate more than Object B because B has greater inertia than AB. Object B will accelerate more than Object A because B has less inertia than AC. Both will accelerate at the same rate because they are weightlessD. Both will accelerate at the same rate because there is no inertia in outer spaceE. This is a trick question. Objects have no mass in outer space A hammer is accidentally thrown out of the starship Enterprise. Now that the hammer is moving, there is no additional force applied. After a short time A.
