experiments
• 1 - Spring dynamometers, acceleration due to gravity, weight

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

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

• 2 - Hooke’s law

### experiment "Hooke’s law"

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

• 3 - Centre of gravity and equilibrium

### experiment "Centre of gravity and equilibrium"

The center of gravity, or more precisely a centroid, of any shaped disk is determined experimentally. The static balance of the disc is then examined.

• 4 - Laws of levers – 1st class levers

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

The law of the lever is illustrated by the two-sided lever.

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

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

The law of the lever is illustrated using the one-sided lever.

• 6 - Elastic deformation – leaf springs

### experiment "Elastic deformation – leaf springs"

During the elastic deformation of a leaf spring, it is examined whether there is a linear relationship between the deflection of the leaf spring and the applied force.

• 7 - Plastic deformation – sand

### experiment "Plastic deformation – sand"

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