Question 1:

Which of the following is an example of an application of Simple Harmonic Motion (SHM)?

A) Pendulum swinging back and forth
B) Car moving on a straight road
C) Projectile motion of a ball
D) Rolling of a wheel on a slope

Show Answer

Explanation: The correct answer is A) Pendulum swinging back and forth. One of the most common applications of Simple Harmonic Motion (SHM) is the motion of a pendulum. A pendulum swings back and forth under the influence of gravity, exhibiting SHM. It is used in various devices such as clocks, metronomes, and seismometers.

Question 2:

Which of the following devices uses Simple Harmonic Motion (SHM) to measure time?

A) Spring scale
B) Thermostat
C) Metronome
D) Oscilloscope

Show Answer

Explanation: The correct answer is C) Metronome. A metronome is a device used by musicians to keep a consistent tempo while playing music. It uses Simple Harmonic Motion (SHM) to measure time. A swinging pendulum inside the metronome creates an oscillatory motion, producing an audible tick-tock sound at a fixed frequency.

Question 3:

Which of the following is an example of an application of Simple Harmonic Motion (SHM) in engineering?

A) Electric guitar string vibrating
B) Magnetic levitation train
C) Airplane flying in the sky
D) Hydraulic lift in an automobile

Show Answer

Explanation: The correct answer is D) Hydraulic lift in an automobile. Hydraulic lifts in automobiles use Simple Harmonic Motion (SHM) to raise and lower the vehicle. The lift system consists of a piston and a cylinder filled with fluid. When pressure is applied to the fluid, the piston undergoes SHM, allowing for controlled lifting and lowering of the automobile.

Question 4:

Which of the following is an application of Simple Harmonic Motion (SHM) in science?

A) Washing machine spinning clothes
B) ECG heart monitor
C) Wind blowing through trees
D) Earthquake-induced vibrations

Show Answer

Explanation: The correct answer is B) ECG heart monitor. An ECG (electrocardiogram) heart monitor is a medical device used to measure the electrical activity of the heart. The heart's electrical signals, including the regular beating pattern, exhibit Simple Harmonic Motion (SHM). By detecting and recording these electrical signals, an ECG provides vital information about heart health and function.

Question 5:

Which of the following is an application of Simple Harmonic Motion (SHM) in physics research?

A) Swing in a playground
B) Atomic force microscope
C) Wind turbine generating electricity
D) Vibrations in a guitar string

Show Answer

Explanation: The correct answer is B) Atomic force microscope. An atomic force microscope is a high-resolution imaging instrument used in physics research to study surfaces at the atomic level. It utilizes a tiny cantilever with a sharp probe that scans the surface of a sample. The deflection and oscillation of the cantilever exhibit Simple Harmonic Motion (SHM), allowing for precise imaging and measurement of atomicforces and surface characteristics.
