Einführung in die Kräfte
Von Oliver Smith
Kräfte sind Stöße und Züge, die alles im Universum regieren. Sie können bewirken, dass sich Dinge bewegen, beschleunigen, verlangsamen, die Richtung ändern oder sogar die Form der Dinge ändern. Die folgenden Aktivitäten helfen den Schülern, Kraft und Bewegung zu verstehen, damit sie die Welt um sie herum besser verstehen können.

- Force Diagram
- The Soyuz orbital module is in orbit. Even though it's speed may be constant it's velocity is changing as it changing direction. Forces are unbalanced. The only force acting on the module is its weight.

- The Soyuz orbital module is in orbit. Even though it's speed may be constant it's velocity is changing as it changing direction. Forces are unbalanced. The only force acting on the module is its weight.
- Weight
-
- The capsule is decelerating so the forces aren't balanced. The drag from the parachute must be larger than the weight of the parachute and the capsule.
- Weight
-
-
- The forces are balanced, as the capsule is not moving. The reaction force acting on the capsule from the ground is equal and opposite to the weight of the capsule.
