What is the relationship between acceleration and displacement in simple harmonic motion?

• Acceleration is directly proportional to displacement.

• Acceleration is unrelated to displacement.

• Acceleration is inversely proportional to displacement.

• Acceleration is proportional to the negative of displacement.

How is angular frequency defined in terms of distance and time?

• Angular frequency is the speed of light in a vacuum.

• Angular frequency is the distance over time for a circular path.

• Angular frequency is the time taken to complete one cycle.

• Angular frequency is the distance traveled in one second.

What is the unit of angular frequency?

• Radians per second

• Meters per second

• Seconds

• Hertz

What does the gradient represent in a linearized equation of motion?

• The gradient represents the y-intercept.

• The gradient represents the slope of the line.

• The gradient represents the x-intercept.

• The gradient represents the area under the curve.

Which equation correctly relates frequency and period?

• Frequency is equal to the period squared.

• Frequency is the reciprocal of the period.

• Frequency is the product of the period and angular frequency.
