2 Waves - Pendulums (oscillators)

When measuring the period of the pendulum in order to find its period, when testing for string length, what variable(s) must be kept constant?

• string length

• mass of the plumb bob

• amplitude

• BOTH mass and amplitude

Which is NOT one of the variable we tested in the pendulum activities?

• length of string

• width of string

• amplitude

• mass of the plumb bob

How many variables are changed in a controlled experiment?

• 1

• 2

• 3

• doesn't matter how many

Where does a pendulum have maximum potential energy?

• equilibrium

• between equilibrium and highest amplitude moving down

• highest amplitude on either side of equilibrium

• between equilibrium and highest amplitude moving up

Where does a pendulum have maximum kinetic energy?

• equilibrium

• between equilibrium and highest amplitude moving down

• highest amplitude on either side of equilibrium

• between equilibrium and highest amplitude moving up

What is happening to the total Mechanical Energy of the pendulum as it swings (conservation of energy)?

• As one energy increases, the other decreases; the total mechanical energy of the system stays the same

• Energy keeps increasing

• The energy is destroyed

• There is twice the energy at the end than at the start
