Physics 112 : May 6 -10

Posted: May 1, 2019

I have posted a word document below with various problem types from this unit so far (up to conservation of momentum). The solutions are posted on the pdf file (physicsmomentumassn.pdf)

 

I have posted an old unit 3 test if any student wants to get ahead start on the test preparation. The test will be the week of May 13 (planning for Tuesday bor Wednesday)

 

Monday - Conservation of Momentum

           - 1 board example

           - impulse

           -  Red p 193 (2,3,4,5,8,9 &11)

           - Green p 200 (30,31,33,& 34)

                     p 209 (37,38,39,42,43 & 45)

                     p 213 (46)

          ***** physicsimpulsemomentummay6.pdf file below ****        

Tuesday - impulse j = FΔt

           - impulse - momentum theorem  FΔt = m(v2 - v1)

Wednesday - Quiz # 4 (conservation of momentum & impulse-momentum theorem) ow on Friday.

Thursday - Springs 

            - Hooke's Law F = kx

            - Elastic potentil energy of a spring EE = 1/2 kx2 

            - Green text p 261(38 - 40)

            - Sprins & conservation of energy.

Friday - Quiz - momentum & impulse - momentum theorem.

                 -Green text p 277 (32 & 34)

                         p 329 (24 & 25)

                         p 333 (47, 49)
