Total questions: 10
Worksheet time: 5mins
Simple harmonic motion or periodic motion is known as a motion in which a body moves back and forth over a fixed path, returning to each position and velocity after a definite interval of time.
Amplitude is define as the pattern of disturbance cause by movement of energy through a medium
The displacement of an object is described by the following equation:
x = 0.25 cos 0.4t
Where x is in meters and t is in seconds. Determine the amplitude and frequency
A= 0.25m
f= 0.64Hz
A= 0.25m
f= 0.4 Hz
A=0.25cm
f=0.64Hz
A= 0.25m
f= 0.064 Hz
An object with a mass of 0.5 kg is undergoing SHM on the end of a horizontal spring with a spring constant k = 400 N/m. When the object is 0.012 m from its equilibrium position, it is observed to have a speed of 0.34 m/s. Calculate the amplitude
0.34m
0.5 m
0.012m
0.012cm
Given the Amplitude is 3.0 m, the angular velocity is 0.5 rad/s and T is 12.6 s.
The sinusoidal motion are starting from zero.
Write the equation of displacement,x, as a function of time, t.
x=3 cos (0.5t)
x=3 sin (0.5t)
x=0.3 sin (0.5t)
x=0.3 cos (0.5t)
Calculate the maximum velocity for this SHM

3.142m/s
15.71m/s
5 m/s
A simple pendulum is swinging on Earth. The period of oscillation will decrease when its moved to a planet with stronger gravitational acceleration.
Which factor does not affect the period of a simple pendulum (assuming small angles)?
Length of the pendulum
Mass of the pendulum bob
Gravitational field strength
Acceleration due to gravity
What happens to the period of a pendulum if its length is quadrupled?
It becomes four times as long
It stays the same
It halves
It doubles
When is the kinetic energy of a mass on a spring at its maximum during SHM?
At maximum displacement
Halfway between equilibrium and maximum displacement
At equilibrium position
At the point it changes direction
