In the mass-spring system diagram, what type of energy is at its maximum at points A, C, and E?
Maximum potential energy, zero kinetic energy.
In the mass-spring system diagram, what type of energy is at its maximum at points B and D?
Maximum kinetic energy, zero potential energy.
In the Energy vs. Time Graph, what does a horizontal line represent?
Total Energy (E) is Constant: No external forces are doing work on the system.
In the Energy vs. Time Graph, what do the curves represent?
The potential and kinetic energy graphs are curves due to the squared term in the potential energy equation ().
What is the effect of increasing the displacement on potential energy?
Increasing the displacement from equilibrium increases the potential energy stored in the system (U = 1/2 kx^2).
What happens to kinetic energy as an oscillator approaches equilibrium?
As the oscillator approaches equilibrium, its kinetic energy increases, reaching its maximum at the equilibrium point.
What happens to potential energy as an oscillator moves away from equilibrium?
As the oscillator moves away from equilibrium, its potential energy increases, reaching its maximum at maximum displacement.
What is the effect of doubling the amplitude on the total energy of SHM?
Doubling the amplitude quadruples the total energy (since energy is proportional to the square of the amplitude).
What happens if non-conservative forces act on a simple harmonic oscillator?
The total energy of the system decreases over time due to energy dissipation (e.g., friction).
What happens if the spring constant is doubled?
The potential energy doubles for the same displacement.
What is the effect of increasing the displacement (x) on potential energy (U)?
Potential energy increases quadratically ().
What happens to kinetic energy as an oscillator approaches its equilibrium position?
Kinetic energy increases, reaching its maximum at the equilibrium position.
What happens to the total energy of a SHM system if there are no non-conservative forces?
The total energy remains constant.
What happens to the total energy of a SHM system if the amplitude of the oscillation is doubled?
The total energy quadruples.
