  1. Let’s Measure… Kate Pallósi KŐSZEG Jurisich Miklós High School

  2. Length - with Watch • The body swings at the end of a string: • mathematical pendulum

  3. Period  length

  4. Mass With Measuring the Length

  5. We measure the cross section of the piston of the syringe Let’s winde the string around the piston, we will get the perimeter, from this the radius and the area. Then we Use Boyle’s law

  6. Density • r • k The string is wound around the sphere

  7. Calculation:

  8. Mass of a rod with another mass • With the aid of torque • x • mg y Mg

  9. Calculation

  10. And • much • more…
