Question 1:

Which of the following statements is true regarding the total mechanical energy in Simple Harmonic Motion (SHM)?

A) The total mechanical energy is conserved throughout the motion
B) The total mechanical energy increases with time
C) The total mechanical energy decreases with time
D) The total mechanical energy depends on the amplitude of the motion

Show Answer

Explanation: The correct answer is A) The total mechanical energy is conserved throughout the motion. In Simple Harmonic Motion (SHM), the total mechanical energy, which includes the potential energy and the kinetic energy, remains constant. As the object oscillates between the two extreme points, the energy continuously converts between potential and kinetic forms, but the total amount of mechanical energy remains the same.

Question 2:

What happens to the kinetic energy of an object in Simple Harmonic Motion (SHM) when it reaches its maximum displacement from the equilibrium position?

A) The kinetic energy is maximum
B) The kinetic energy is minimum
C) The kinetic energy is zero
D) The kinetic energy depends on the mass of the object

Show Answer

Explanation: The correct answer is C) The kinetic energy is zero. In Simple Harmonic Motion (SHM), the kinetic energy of the object is maximum at the equilibrium position and decreases as it moves away from the equilibrium. When the object reaches its maximum displacement, its velocity becomes zero, and therefore, the kinetic energy is zero. At that point, all the energy is in the form of potential energy.

Question 3:

What happens to the potential energy of an object in Simple Harmonic Motion (SHM) when it reaches its maximum displacement from the equilibrium position?

A) The potential energy is maximum
B) The potential energy is minimum
C) The potential energy is zero
D) The potential energy depends on the mass of the object

Show Answer

Explanation: The correct answer is A) The potential energy is maximum. In Simple Harmonic Motion (SHM), the potential energy of the object is maximum when it reaches its maximum displacement from the equilibrium position. At that point, the object is farthest from the equilibrium, and all its energy is in the form of potential energy. As the object moves towards the equilibrium, the potential energy decreases, and the kinetic energy increases.

Question 4:

What is the relationship between the amplitude and the maximum potential energy in Simple Harmonic Motion (SHM)?

A) They are directly proportional
B) They are inversely proportional
C) There is no relationship between the amplitude and the maximum potential energy
D) The relationship depends on the frequency of the motion

Show Answer

Explanation: The correct answer is A) They are directly proportional. In Simple Harmonic Motion (SHM), the amplitude and the maximum potential energy are directly proportional. The amplitude represents the maximum displacement from the equilibrium position, and as the displacement increases, the potential energy also increases. Therefore, a higher amplitude results in a higher maximum potential energy.

Question 5:

What is the relationship between the amplitude and the maximum kinetic energy in Simple Harmonic Motion (SHM)?

A) They are directly proportional
B) They are inversely proportional
C) There is no relationship between the amplitude and the maximum kinetic energy
D) The relationship depends on the mass of the object

ShowAnswer

Explanation: The correct answer is B) They are inversely proportional. In Simple Harmonic Motion (SHM), the amplitude and the maximum kinetic energy are inversely proportional. As the amplitude increases, the maximum displacement from the equilibrium position increases, resulting in a higher potential energy. However, the kinetic energy is highest at the equilibrium position and decreases as the object moves away from it. Therefore, a higher amplitude leads to a lower maximum kinetic energy.
