Spring Oscillations
1. What is the spring constant?
- Restoring force per unit displacement
- The time required for one oscillation
- The length of the spring at rest
- The weight of the mass on the spring
2. What does the spring constant physically represent?
- A measure of how stiff a spring is
- The number of oscillations per second
- The distance between coils
- The energy stored in a spring
3. What happens when the spring constant increases?
- Stiffness increases and more torque is required
- Stiffness decreases
- Less torque is required to compress the spring
- Oscillations become slower
4. What is parallax error?
- An error from viewing the scale at an angle rather than perpendicular
- The difference in readings due to temperature
- A type of reading error due to friction
- A fault in the instrument
5. What is angular velocity?
- Angular displacement divided by time
- The number of cycles per second
- Torque divided by mass
- Change in radius over time
6. What is angular acceleration?
- Change in angular displacement per second
- Rate of change of torque
- Rate of change of linear displacement
- Rate of change of angular velocity with respect to time
7. What is angular SHM?
- Oscillatory motion where torque is proportional to angular displacement
- Rotation around a fixed axis with constant velocity
- Non-periodic angular movement
- Constant rotational motion
8. What is the difference between angular velocity and angular speed?
- Angular velocity is scalar, angular speed is vector
- There is no difference
- Both are scalar quantities
- Angular velocity includes direction; angular speed does not
9. Why is the system kept horizontal in angular SHM experiments?
- To align with the spring’s natural direction
- Because gravity doesn't affect it
- To reduce friction
- To ensure torque is maximum due to sinθ being maximum at 90°
10. What is a common daily use of a spring system as described?
- Used in light bulbs
- Used in ceiling fans
- Used in cars to absorb bumps
- Used in thermometers
