# Class set Mechanics 2.0

Possibility to tie in with mathematics:

• Use of age-appropriate statistics when evaluating
• Testing for proportional correlations
• Introduction of vector summation with overlapping forces.

A geometric analysis is included in the manual.

This kit covers the following basic laws of physics:
• Newton’s 2nd law
• Hooke’s law
• Archimedes law of the lever
• can be used for stationery work
• no special room necessary!

experiments
• 1 - Laws of levers – 1st class levers

### experiment "Laws of levers – 1st class levers"

On the two-sided lever, the leverage law is clarified.

• 2 - Plastic deformation – sand

### experiment "Plastic deformation – sand"

In the plastic deformation of sand, it is investigated whether the crater diameter generated when a steel ball falls into sand depends linearly on the fall height.

• 3 - Spring dynamometers, acceleration due to gravity, weight

### experiment "Spring dynamometers, acceleration due to gravity, weight"

The use of a force gauge is learned when determining the weight force. The location factor is introduced or repeated. Finally, when comparing the measured values with theoretical values, the accuracy of the force gauge is discussed.

• 4 - Hooke’s law

### experiment "Hooke’s law"

In this experiment, the elongation of a spring as a function of the force exerted on the spring is investigated.

• 5 - Centre of gravity and equilibrium

### experiment "Centre of gravity and equilibrium"

The center of gravity, or more precisely a heavy axis, of an arbitrarily shaped disc is determined experimentally. Subsequently, the static equilibrium of the disk is examined.

• 6 - Laws of levers – 2nd & 3rd class levers

### experiment "Laws of levers – 2nd & 3rd class levers"

On the one-sided lever, the leverage law is clarified.

• 7 - Elastic deformation – leaf springs

### experiment "Elastic deformation – leaf springs"

In the elastic deformation of a leaf spring, it is investigated whether there is a linear relationship between the deflection of the leaf spring and the attacking force.
