Questions and Answers

What is the formula for the restoring force in Hooke's Law?

F = -sk
F = -ks (correct)
F = k/s
F = s/k

Which of the following systems executes Simple Harmonic Motion?

A rocket ascending into space
A car moving on a straight road
A boat sailing on a lake
A mass oscillating up and down on a spring (correct)

What is the formula for frequency in SHM?

Frequency = (no of oscillations)/(time taken) (correct)
Frequency = (time taken)/(no of oscillations)
Frequency = time taken x no of oscillations
Frequency = time taken / no of oscillations
