4 cards from this section. Quick, good the night before a test.
Define oscillation.
Think about how a swing moves.
What is the unit for frequency?
How many cycles happen in one second?
What is the definition of oscillation?
Think of a swing or a pendulum.
A pendulum swings back and forth; this is an example of what type of motion?
Consider if it's repeating or continuous.
A mass oscillating on a spring has a spring constant of 400 N/m and is displaced 0.2 m. Find (a) its potential energy when displaced, (b) its period.
Recall potential energy formula and relationship between mass and spring constant.
A pendulum makes 40 oscillations in 1 minute. Calculate its period and frequency.
Utilize the definitions of period and frequency with the total oscillations given.
