Arbeitsauftrag 2
1. Ein Fadenpendel (ein Faden mit Gewicht unten) wird ausgelenkt und losgelassen.
Beschreibe die Energiesituationen bei 1 (Start), 2, 3, 4 und 5 mit eigenen Worten.

Hey Leute danke das ihr mir helfen wollt diese Frage zu beantworten!

Ich habe schon alle auf dem Blatt gefragten Aufgaben gelöst, weiß aber nicht wie ich diese hier beantworten soll.

Ich freue mich auf eure hilfreichen Antworten!!

LG

Explanation:

The height of the pendulum is measured from the lowest point it reaches (point 3).

At 1, the kinetic energy of the pendulum is zero (because it is not moving), and it has maximum potential energy.

At 2, the pendulum has both kinetic and potential energy, and how much of each it has depends on its height—smaller the height greater the kinetic energy and lower the potential energy.

At 3, the height is zero; therefore, the pendulum has no potential energy, and has maximum kinetic energy.

At 4, the pendulum again gains potential energy as it climbs back up,  Again how much of each forms of energy it has depends on its height.

At 5, the maximum height is reached again; therefore, the pendulum has maximum potential energy and no kinetic energy.

Hope this helps :)

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
