Boxer

HOW

1. Look at the display. The “ready” message means you can use the device.
2. Hit the boxing pear as hard as you can.
3. Check the result on the display.

WHY

The obtained result is the average speed of the boxing pear’s arm movement, expressed in radians per second. The greater the force of the punch, the greater the average speed of the arm.

This experiment deals with the transfer of energy from the punch to the boxing pear. The amount of transferred energy depends on the mass of the striking object and its speed.
