episode 10: The APsolute RecAP: Physics 1 Edition - Dynamics - Newton’s Laws and Solving Force Problems
Forces are introduced and the variety of forces are explained. (1:30) Newton’s 1 Law is introduced and so are Free-Body Diagrams. (3:05) Newton’s 2nd Law is stated and the concept of defining a system is discussed. (6:07) Next, Newton’s 3rd Law, the easiest to state, but hardest to apply is presented. (7:33) Finally, a universal problem solving method for all force problems is laid out, and frictional forces are explored. (9:53)
The Question of the Day asks: (11:02)
If you double the mass of a system without changing the net external force, what will the effect on acceleration be?
a) acceleration is doubled
b) acceleration is halved
c) there is no change to the acceleration
