WebDescription. Lesson 1: Forces. Xtra Gr 11 Physical Sciences: In this lesson on Forces we define the concept of a force. We prepresent forces using vector diagrams. We solve problems when two or more forces acting on an object. Finally, we identify different forces including friction and the normal force. Lesson 2: Newton's Laws. WebThe force of gravity (Fg - also called gravitational force) is an act at a distance force. It is the force of attraction between any two objects. To calculate the magnitude of the force of gravity we can use the following: …
