Forced Oscillation and Resonance demo
Product Code : JA-SW-7595
The Forced Oscillation and Resonance demo (SKU JA-SW-7595) shows how an object vibrates when repeated impulses are applied to it and how its motion builds up when the driving frequency matches its natural frequency. It consists of two weights with different natural frequencies, two cams driven by a 6 V motor with speed control, and four springs, and it is supplied with a manual. JaincoLab supplies this forced oscillation and resonance demonstrator for school and college physics teaching.
Specifications
The demonstrator combines two weights of different natural frequencies, four springs and two cams turned by a 6 V motor, with a speed control that sets the frequency of the applied force; the unit measures 30 × 15 × 45 cm, a manual is included and the power source is not.

Demonstrating resonance with the forced oscillation apparatus
The apparatus is used to demonstrate forced oscillation and resonance: as the motor speed is changed, each weight vibrates most strongly when the frequency of the applied force matches its own natural frequency, so students can find the resonance condition for two different systems with one set-up.
- Showing the vibration of an object under repeated impulses (forced oscillation)
- Finding the driving frequency at which each weight resonates
- Comparing two oscillators with different natural frequencies
- Senior-secondary and college lessons on oscillations, resonance and waves

Frequently asked questions
What does the Forced Oscillation and Resonance demo consist of?
Two weights of different natural frequencies, two cams driven by a 6 V motor with speed control, four springs and a manual.
How is resonance reached?
The speed control adjusts the frequency of the applied force until it matches the natural frequency of a weight, which then vibrates strongly.
Is a power supply included?
No. The power source is not included; the motor is a 6 V type, and a suitable supply can be quoted separately.
What is the size of the unit?
It measures 30 × 15 × 45 cm.
