Starting a Pendulum With Force
Think about the question below. Only one of the answers listed is correct. We'll do some (but probably not all) of these questions in the lectures when you will all be asked to vote on which answer you think is correct. (Soon afterwards, you'll be able to see your responses, and those of the whole class at EVAF.)
A mass on a spring is displaced by an amount x(0). It is set in motion travelling at speed v(0)
- [(A)] towards the equilibrium position
- [(B)] away from the equilibrium position.
The amplitude of oscillation is
1 | larger in case A |
2 | larger in case B |
3 | the same for A and B |
