Balanced Forces Worksheet 1
... 4. Suppose that we could somehow succeed in making the floor completely frictionless. Just as in problems #1-3 the box sits at rest for a while, then is pushed so that it starts to move, and then loses contact with the person’s hands and moves across the now frictionless floor. a. Draw a qualitative ...

... 20. A 50 kg gymnast exerts horizontal and vertical forces of 700 N and 1200 N, respectively, on a vaulting horse. Assuming the forces are constant over a 0.30 s contact period, calculate the following a. Net horizontal impulse she generates b. Net vertical impulses she generates c. Change in horizon ...

... Force is a vector quantity. The equation on the previous slide gives the magnitude of the force. If the charges are opposite in sign, the force is attractive; if the charges are the same in sign, the force is repulsive. Also, the constant k is equal to 1/40, where 0=8.85x10-12 C2/N·m2. I could w ...

10.2 Charging by Contact and by Induction
... way. Increasing your distance from Earth in a spaceship would result in a decreased force of gravity between you and Earth. To determine whether an object is charged and, if so, what type of charge it has, you must observe repulsion between it and another object. Once you observe repulsion occurring ...
