What is the formula for calculating the kinetic energy (K.E.) in simple harmonic motion (S.H.M)?

Detailed Solution for Test: Oscillations - Force law & Energy in simple harmonic motion (8 Oct) - Question 3

The formula for calculating kinetic energy (K.E.) in simple harmonic motion is K.E. = 1/2 mv2, where 'm' is the mass of the object and 'v' is its velocity.

What is the total energy (T.E.) in simple harmonic motion?
Detailed Solution for Test: Oscillations - Force law & Energy in simple harmonic motion (8 Oct) - Question 4

The total energy (T.E.) in simple harmonic motion is the sum of its kinetic energy (K.E.) and potential energy (P.E.), given by T.E. = K.E. + P.E.

In simple harmonic motion, what happens to the velocity of the object when it reaches its extreme position?
Detailed Solution for Test: Oscillations - Force law & Energy in simple harmonic motion (8 Oct) - Question 5
In simple harmonic motion, when the object reaches its extreme position, its velocity becomes zero. This occurs because the object momentarily stops before changing direction.

What is the formula for calculating potential energy (P.E.) in simple harmonic motion (S.H.M)?
Detailed Solution for Test: Oscillations - Force law & Energy in simple harmonic motion (8 Oct) - Question 6

The formula for calculating potential energy (P.E.) in simple harmonic motion is P.E. = 1/2 kx2 = 1/2 mω2x2 , where 'k' is the force constant and 'x' is the displacement from the equilibrium position.

At what position in simple harmonic motion (S.H.M) is the total energy purely kinetic?
Detailed Solution for Test: Oscillations - Force law & Energy in simple harmonic motion (8 Oct) - Question 7
At the mean position in simple harmonic motion, the total energy is purely kinetic. This is because the velocity is maximum and the displacement is minimum at the mean position.

What is the unit of the force constant 'k' in the force law of simple harmonic motion?
Detailed Solution for Test: Oscillations - Force law & Energy in simple harmonic motion (8 Oct) - Question 8
The unit of the force constant 'k' in the force law of simple harmonic motion is N/m (Newtons per meter). It represents the stiffness of the restoring force.
Test: Oscillations - Force law & Energy in simple harmonic motion (8 Oct) - Question 9
Save
What is the condition for the restoring force in simple harmonic motion (S.H.M)?
Detailed Solution for Test: Oscillations - Force law & Energy in simple harmonic motion (8 Oct) - Question 9
The restoring force in simple harmonic motion always acts in the opposite direction of the displacement from the equilibrium position.
Test: Oscillations - Force law & Energy in simple harmonic motion (8 Oct) - Question 10
Save
In the equation for the force law of simple harmonic motion, what does 'k' represent?
Detailed Solution for Test: Oscillations - Force law & Energy in simple harmonic motion (8 Oct) - Question 10
In the force law of simple harmonic motion, 'k' represents the force constant, which is a measure of the stiffness of the restoring force.
