Which of following graphs describes simple periodic motion with amplitude 2.00 cm and angular frequency 2.00 rad/s?

Question

Quizplus · Accepted Answer

Simple periodic motion with amplitude A and angular frequency ω can be represented by the equation y = A sin(ωt). 
In this case, amplitude = 2 cm and angular frequency = 2 rad/s. 
Using the equation, we can plot the displacement (y-axis) vs time (x-axis) graph for one complete cycle of the motion. 
Choice B shows such a graph with amplitude 2 cm and angular frequency 2 rad/s. Therefore, B is the best choice.
