Einführung in die Kräfte

Unterrichtspläne von Oliver Smith

Kräfte sind Stöße und Zerrungen, die alles im Universum regieren. Sie können bewirken, dass sich Dinge bewegen, beschleunigen, verlangsamen, die Richtung ändern oder sogar die Form von Dingen ändern. Von den größten Gravitationskräften, die unser Universum zusammenhalten, bis zu den Kräften, die die kleinsten Teilchen in Atomen zusammenhalten, haben Wissenschaftler Jahrtausende damit verbracht, Kräfte zu verstehen. Die folgenden Aktivitäten helfen den Schülern, Kraft und Bewegung zu erfassen, um die Welt um sie herum besser zu verstehen.

  • Example
  • 
  • 
  • 
  • 
  • 
  • A rocket accelerating upwards
  • 
  • 
  • 
  • Thrust
  • A Soyuz orbital module in orbit
  • 
  • 
  • A Soyuz re-entry capsule just after the parachute has been released
  • 
  • 
  • 
  • 
  • Drag
  • A Soyuz re-entry capsule at rest on the ground
  •

  • 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.

  • Drag
  • 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.
