 # Rod and gravity pendulum (TM 161)

SKU TM161

investigation of pendulum swings

 Code TM161

Description:

• 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.
