Circular Motion and Gravity
... • The gravitational forces that two masses exert on each other are always equal in magnitude and opposite in direction. • This is an example of Newton’s third law of motion. • One example is the Earth-moon system, shown on the next slide. • As a result of these forces, the moon and Earth each orbit ...

Work and the Work-Energy Principle
... • Work is what is accomplished by a force acting on an object (i.e., movement in the direction of that particular force) • Work is a scalar quantity - no direction • It can, however, be either positive or negative. Positive if the object moves at least partly in the direction of the force. Negative ...
