Question
1. How do you get the algebraic expression for the velocity of a block in SHM?
a. Take the derivative of the acceleration function.
b. Take the integral of the position function.
c. Take the derivative of the position function.
2. In the simple harmonic motion of a block on a spring, where is the block when the kinetic energy is maximum?
a. It is at a point of its position amplitude.
b. It is at the midpoint of its oscillation
c. It is at a point of maximum displacement
3. In the simple harmonic motion of a block on a spring, as the potential energy is decreasing, which of the following is true?
a. The kinetic energy and the total energy are both decreasing
b. The kinetic energy is increasing and the total energy is decreasing
c. The kinetic energy is increasing and the total energy is constant
d. The kinetic energy is decreasing and the total energy is increasing
e. The kinetic energy is decreasing and the total energy is constant.
f. The kinetic energy and the total energy are both increasing
4. In the simple harmonic motion of a block on a spring, what is the restoring force proportional to?
a. the period of the motion
b. the angular frequency
c. the negative of the angular speed
d. the negative of the displacement
Explanation / Answer
c. Take the derivative of the position function.
because: from the defination of velocity:
v = d(x)/dt
2)(a)It is at a point of its maximum displacement.
because, KE = 1/2 k A^2
3)c. The kinetic energy is increasing and the total energy is constant
from conservation of energy principle.
4)d. the negative of the displacemen
because, restoring force is:
F = -kx
