5. Universal Laws of Motion
... How did Newton change our view of the universe? • He realized the same physical laws that operate on Earth also operate in the heavens: one universe • He discovered laws of motion and gravity. • Much more: Experiments with light; first reflecting telescope, calculus… Sir Isaac Newton ...

Gravity
... On Earth, we have air. Air resistance will cause some objects to fall more slowly than others will. This works to our advantage when we want to fall more slowly, for example, when a skydiver jumps out of an airplane. He uses a parachute to create as much air resistance as possible to slow down his f ...

... Standing here, my acceleration is zero and the net force on me is zero. The Earth is still pulling me down but the floor is pushing me up with the same force. I’ll try not to fall. Weight is the gravitational force on an object. Weight = mass x acceleration due to gravity (W=mg) W = m x 9.8 m/s2 ( ...
