investigation of pendulum swings
- Pendulums perform oscillations. Gravity produces the restoring moment.
- We distinguish between mathematical and physical pendulums.
- A mathematical pendulum describes an idealised gravity pendulum.
- In physical pendulums, the shape and size of the pendulum body is taken into account.
- Both are theoretical models for the description of a real pendulum.
- The TM 161unit is used to study pendulum swings.
- A gravity pendulum (mathematical pendulum) and a rod pendulum (as a physical pendulum) are compared to each other.
- The unit contains a metal rod with a movable auxiliary mass as the rod pendulum.
- The suspension point can be adjusted on the knife-edge bearing of the pendulum.
- The length of the gravity pendulum can be easily changed using a clamping device.
- The experimental unit is designed to be fixed to a wall.
- experiments on pendulum swings, comparison of physical and mathematical pendulums
- rod pendulum as physical pendulum, made of metal and mounted on knife-edge bearing
- knife-edge bearing mounted to slide on the rod to effectively vary the pendulum length
- weight for the rod pendulum, sliding
- gravity pendulum as a mathematical pendulum
- adjustable length of the gravity pendulum
- stopwatch to measure the oscillation period
- bracket for wall mounting
