Show hintHide hint
Remember the components: Amplitude, Angular Frequency, and Phase.
Question 2.
Define potential energy in SHM.
Show hintHide hint
Consider how displacement affects potential energy.
3Question 3.
What equation represents velocity in SHM?
- v(t) = Aωcos(ωt + φ)
- v(t) = -Aωsin(ωt + φ)
- v(t) = A²ω²cos(ωt + φ)
Show hintHide hint
Check the trigonometric functions used.
4Question 4.
True or False: The total mechanical energy in an SHM remains constant.
- True
- False
Show hintHide hint
Consider the energy transformations occurring in SHM.
Question 5.
A mass of 2 kg is undergoing SHM with an amplitude of 0.5 m and a spring constant of 200 N/m. Compute the total energy and express the kinetic energy when the displacement is 0.25 m.
Show hintHide hint
Calculate total energy first, then use P.E. to find K.E.
Question 6.
If the maximum speed of a mass in SHM is 4 m/s and its mass is 1 kg, find the maximum kinetic energy.
Show hintHide hint
K.E. depends on mass and the speed at the mean position.
