Master the concepts 1. Force is a push or pull, all forces exerted on macroscopic objects are contact forces. 2. Vectors have magnitude and direction. 5. Components of a vector are the projections on the coordinate axes. 4. The net force on a system is the vector sum of the external forces on it. 5.

Unformatted text preview: Free body diagram is every external force acting on that body. 6 . Newton’s third law “each object exerts an equal and opposite force on each other”. 7. Four fundamental interactions, gravity, the strong and weak interactions and the electromagnetic interactions. 8. The magnitude of the gravitational force between two objects is F=Gm1m2/r2. 9. The weight of an object is W=mg. 10. Friction is a contact force. The kinetic frictional force and the maximum...
