Card 1
Question: What is an oscillation?
Answer: An oscillation is a repetitive variation, typically in time, of some measure about a central value or between two or more different states.
Card 2
Question: What type of oscillation is the simplest and most important?
Answer: Simple Harmonic Motion (SHM).
Card 3
Question: When does Simple Harmonic Motion (SHM) occur?
Answer: SHM occurs when the restoring force acting on an object is directly proportional to its displacement from an equilibrium position and acts in the oppo
Card 4
Question: What is the mathematical expression for the restoring force in SHM?
Answer: F = -kx, where F is the restoring force, k is the spring constant, and x is the displacement from equilibrium.
Card 5
Question: What does the negative sign indicate in the SHM restoring force equation?
Answer: The negative sign indicates that the force always acts to restore the object to its equilibrium position.
Card 6
Question: Name two classic examples of systems exhibiting SHM.
Answer: The mass-spring system and the simple pendulum.
Card 7
Question: What provides the restoring force in a mass-spring system undergoing SHM?
Answer: The spring provides the restoring force.
Card 8
Question: What is the formula for the period (T) of a mass-spring system?
Answer: T = 2π√(m/k), where m is the mass and k is the spring constant.
Card 9
Question: What are the units for mass (m) and spring constant (k) in the mass-spring period formula?
Answer: Mass (m) is in kilograms (kg) and spring constant (k) is in newtons per meter (N/m).
Card 10
Question: What approximates SHM for small angles of displacement in a simple pendulum?
Answer: A small mass (bob) suspended by a light, inextensible string swinging freely under gravity.
