31
Lesson Objectives Introduce the concept of resonance when an oscillator is driven by a source Introduce the concept of resonance when an oscillator is driven by a source Explain and measure how resonance is a result of the driving frequency being similar to natural frequency Explain and measure how resonance is a result of the driving frequency being similar to natural frequency Be able to use F=ks to calculate spring constant k and calculate periodicity Be able to use F=ks to calculate spring constant k and calculate periodicity Understand how the resonance peak is usually very narrow without damping Understand how the resonance peak is usually very narrow without damping

Question Hints

42
Hints for 110S 1.You will have to do quite a bit of rearranging of equations. 6.Think of the definition of potential difference when you are trying to work out how much energy is involved in passing charge through a battery.

43
Hints for 150S 2.Write an equation for distance travelled. Distance is the area under your sketched velocity–time graph.

44
Hints for 220S 3.To calculate the amount of stretch, consider the loss of gravitational potential energy of the jumper, all changed to elastic strain energy. You will end up with a quadratic equation to solve. 3.To calculate the amount of stretch, consider the loss of gravitational potential energy of the jumper, all changed to elastic strain energy.

45
Hints for 210D 1.Just remember that the kinetic energy at any point = total energy – stored energy.
