Description of Centre Of Percussion

This product is part of a range that explores free vibrations in simple one degree of freedom systems. It introduces students to key scientific terms such as:

• Simple harmonic motion and period of oscillation
• Radius of gyration
• Centre of gravity
• Centre of percussion and the sweet spot
• Impact reactions

Centre Of Percussion fits to the sturdy Test Frame for study or demonstration. A centre of percussion may also be termed the sweet spot of the impact of a ball against a bat or racquet. It is the impact position which allows no reaction in the hand of the user, which would otherwise create uncomfortable shocks in their arm and wrist. Centre Of Percussion includes a metal pendulum to provide the percussion force and a wooden pendulum to absorb the impact. The wooden pendulum forms a suspended mass, similar to a bat held underhand.
