PHY 104 Oscillatory Motion Objective Question

Question

For an object's motion along the x-axis to be periodic with a period T, which mathematical condition must be satisfied?
Options
A x(t + T) = x(t)
Correct Answer
B x(t * T) = x(t)
C x(t - T) = x(t)
D x(t) / T = x(t)
Correct Answer

Option A is the correct answer.

Detailed Explanation

As stated in the 'Periodic Motion in One Dimension' section on page 1, the condition for periodic motion is x(t + T) = x(t), also labeled as equation 1a.

Hint

Look for the mathematical definition of period in the one-dimensional periodic motion section.
