AP Physics 1 - Simple Harmonic Motion

How does the spring constant (k) affect the period of a mass-spring system?

• A larger spring constant results in a shorter period, meaning the system oscillates faster.

• A larger spring constant results in a longer period, meaning the system oscillates slower.

• The spring constant has no effect on the period of the system.

• The period is directly proportional to the spring constant.

What does the term 'simple harmonic motion' refer to?

• A type of periodic motion where the restoring force is directly proportional to the displacement from the equilibrium position.

• A type of motion that occurs in a straight line without any periodicity.

• A motion that involves constant acceleration in a circular path.

• A type of motion that is random and unpredictable.

What is the relationship between potential energy and kinetic energy in simple harmonic motion?

• The total mechanical energy is conserved, and potential energy is maximum at maximum displacement while kinetic energy is maximum at the equilibrium position.

• Kinetic energy is always greater than potential energy throughout the motion.

• Potential energy and kinetic energy are equal at all points in the motion.

• Potential energy is maximum at the equilibrium position and kinetic energy is maximum at maximum displacement.

What is the effect of damping on simple harmonic motion?

• Damping increases the amplitude of oscillations over time.

• Damping has no effect on the amplitude of oscillations.

• Damping reduces the amplitude of oscillations over time, leading to a gradual loss of energy.

• Damping causes the oscillations to become faster and more frequent.

What is the significance of the equilibrium position in simple harmonic motion?

• It is the position where the net force acting on the mass is zero, and the mass oscillates around this point.

• It is the maximum displacement from the mean position.

• It is the point where the mass comes to rest permanently.

• It is the position where the velocity of the mass is at its maximum.

In a velocity-time graph for a mass-spring system, what does the point of zero velocity represent?

• It represents the points of maximum displacement (amplitude) in the motion.

• It indicates the system is at rest and not moving.

• It shows the average velocity of the system over time.

• It marks the point of minimum displacement in the motion.

What type of energy is stored in a compressed or stretched spring?

• Kinetic energy

• Thermal energy

• Elastic potential energy

• Gravitational potential energy

What is the role of the restoring force in simple harmonic motion?

• The restoring force acts to bring the mass back to its equilibrium position, enabling oscillation.

• The restoring force increases the mass's speed indefinitely.

• The restoring force prevents the mass from moving at all.

• The restoring force only acts when the mass is at its maximum displacement.

What is angular frequency in simple harmonic motion?

• Angular frequency (ω) is related to the period (T) by the formula ω = 2π/T.

• Angular frequency (ω) is the maximum displacement from the equilibrium position.

• Angular frequency (ω) is the rate of change of velocity in circular motion.

• Angular frequency (ω) is the time taken for one complete cycle of motion.

How does adding mass to a mass-spring system affect its period?

• Decreases the period of oscillation.

• Has no effect on the period of oscillation.

• Increases the period of oscillation.

• Makes the system oscillate faster.
