Compare kinetic and potential energy in SHM.
Kinetic energy: Energy of motion, maximum at equilibrium. Potential energy: Stored energy, maximum at maximum displacement.
Differentiate between maximum velocity and maximum displacement in SHM.
Maximum velocity: Occurs at the equilibrium position. Maximum displacement: Occurs at the amplitude (farthest point from equilibrium).
What is the effect of doubling the amplitude in SHM on total energy?
The total energy increases by a factor of four (quadruples).
What happens to kinetic energy as an oscillating object moves towards its equilibrium position?
Kinetic energy increases as the object gains speed.
What happens to potential energy as a spring is maximally compressed?
Potential energy is at its maximum.
What is the effect of increasing the spring constant on the maximum speed?
Increasing the spring constant increases the maximum speed.
What happens to the total energy of a system if friction is present?
The total energy decreases over time as mechanical energy is converted into thermal energy.
What happens to the velocity of an object at maximum displacement?
The velocity is zero.
Define Simple Harmonic Motion (SHM).
Periodic motion where the restoring force is proportional to the displacement and acts in the opposite direction.
What is kinetic energy?
Energy possessed by an object due to its motion.
What is potential energy?
Energy stored in an object due to its position or configuration.
Define amplitude in the context of SHM.
The maximum displacement of an object from its equilibrium position during oscillation.
Define equilibrium position in SHM.
The point where the net force on the oscillating object is zero.
Define spring constant (k).
A measure of a spring's stiffness; the force required to stretch or compress the spring by a unit length.
