Osicillation

Question 1

What are oscillations?

Answer 1

measuring the forces that causes objects to oscillate

Question 2

What type of force do we look into when we are analyzing oscillation behavior?

Answer 2

The force (Fe) that we are analyzing is the force of restoration, for that reason you will always notice that the force has a negative in front. ( Hooke’s law)

Question 4

What are pendulums?

Answer 4

1. swinging things
