2 cards from this section. Quick, good the night before a test.
What is the equation that defines Simple Harmonic Motion?
Look for a cosine function!
Define amplitude in the context of SHM.
Think about how far the object moves from its resting position.
What does the amplitude represent in SHM?
Think about the maximum stretch of the motion.
True or False: The phase constant affects the speed of oscillation.
Does it change the rate at which the object oscillates?
A mass attached to a spring undergoes SHM. If the spring constant is 300 N/m and the mass is 3 kg, calculate the angular frequency.
Remember the formula for angular frequency!
Given the displacement function x(t) = 2 cos(3t + π/4), find the amplitude and phase constant.
Identify A and φ from the equation!
