To me, Physics sounds like this: “There were two camels, one of them was red. What is the weight of sand in the desert when it is dark?“
???
Then you haven‘t worked with NTL devices- with them, hands-on Physics is understandable, interesting and entertaining
DM347-1F Free-fall apparatus „Jumbo“
2 For measuring the fall time of a 60 mm wooden ball. The course of the experiment can be seen from a distance due to the size of the ball and the large collecting vessel, making it extremely effective yet still very easy to carry out.
•
Robust metallic holder; two simultaneously adjustable trigger clamps enable optimal time triggering (without residual friction or residual magnetism)
•
60 mm wooden ball with metal axle and position marking
•
Large collecting vessel made of impact-resistant PP; upper opening 270 x 165 mm; inlaid foam rubber-damped impact plate
Dimensions of collecting vessel: 300 x 200 x 130 mm

Information about protection class: Due to the reinforced insulation, the power supply complies with the requirements of protection class II.
Icon protection class II
Equipment which correspond to protection class II has a double insulation or reinforced insulation between mains circuit and output voltage. This precaution is also called protective insulation II (protected electrical separation). Even if you have electroconductive surfaces, they are protected against contact with other voltage-carrying parts.
The long cable (aprrox. 180 cm) allows an electrical supply from the sidewall or the ceiling
