= = =THE ICE WILL TAKE PLACE ON = =FRIDAY, JANUARY 8, 2010! = = = =As someone noted, my ICEs seems to bring on ice. If there is a delayed opening, you will begin your ICE tomorrow and will finish it during the next class. If there is no school, the ICE will take place on Monday. = = = =What you have to know for the next Physics ICE: = = The little bit we said about Aristotle and Galileo = =Newton's Laws - including the concept of inertia, F=ma, and action/reaction statements = =Drawing free-body diagrams = =Using free-body diagrams to solve for the sum of the force vectors and then finding acceleration = =After finding acceleration from F=ma. using it in The Big 5 = =Using The Big 5 to find acceleration and then using that to find force = =Doing free-body diagrams for objects in equilibrium = =Solving for the tensions in ropes (or bars) supporting an object in equilibrium = =Using a vector addition chart to solve for an unknown force if the sum of the forces is known. = =<span style="color: #000000; font-family: Arial,Helvetica,sans-serif;">Solving problems for systems of objects connected by ropes - i.e. finding the acceleration of the system and the tension in the rope(s) connecting the objects = =<span style="color: #000000; font-family: Arial,Helvetica,sans-serif;">Solving problems involving objects on inclined planes (formulas to be given to H, but not to S) = =<span style="color: #000000; font-family: Arial,Helvetica,sans-serif;">Drawing normal forces = =<span style="color: #000000; font-family: Arial,Helvetica,sans-serif;">Determining the magnitude of the normal force if information on the mass of the object and additional outside forces is given. = =<span style="color: #000000; font-family: Arial,Helvetica,sans-serif;"> = =<span style="color: #000000; font-family: Arial,Helvetica,sans-serif;">FOR PERIODS 2, 3 and 9 = =<span style="color: #000000; font-family: Arial,Helvetica,sans-serif;">Finding apparent weight for objects in accelerating systems, such as elevators. = =<span style="color: #000000; font-family: Arial,Helvetica,sans-serif;"> = =<span style="color: #000000; font-family: Arial,Helvetica,sans-serif;">FOR PERIOD 2 = =<span style="color: #000000; font-family: Arial,Helvetica,sans-serif;">Friction problems = ​
