Physics and Our Universe: How It All Works

Using Newton's Laws: 1-D Motion (1x8)

Newton’s second law provides the link between force and acceleration. One important force is gravity, which, near Earth’s surface, results in a force called weight that is proportional to an object’s mass. Because weight and mass are proportional, all objects experience the same gravitational acceleration. If you weigh yourself in an elevator, your apparent weight will be greater than normal as the elevator accelerates upward and less than normal when it accelerates downward.
