Simple Harmonic Motion

Question 1

Force exerted by a spring

Answer 1

F=kx

Question 2

Elastic potential energy

Answer 2

Question 3

True or false: the displacement (x) have an effect on the period (time taken to complete a cycle)

Answer 3

False: increasing displacement increases elastic potential energy thus increasing the velocity; thus the period remains the same.

Question 4

What affects the period in a simple harmonic motion of a spring?

Answer 4

Larger mass = longer period
Larger spring constant = shorter period.

Question 5

The formula to calculate the period of a simple harmonic motion of a spring.

Answer 5

Question 6

Wave formula

Answer 6

V=f x lambda
V = velocity
f = frequency
Lambda = wavelength

Question 8

Force, velocity, and power formula

Answer 8

P = Fv

Question 9

Ohms law

Answer 9

V = IR
V = potential difference
I = current
R = resistance

Question 10

The formula needed to find the period of a simple harmonic motion of a pendulum

Answer 10

l = length of rope
g = acceleration due to gravity
