Введение в Силы
Оливер Смит
Силы — это толчки и притяжения, которые управляют всем во вселенной. Они могут заставить вещи двигаться, ускоряться, замедляться, менять направление или даже изменять форму вещей. Следующие упражнения помогут учащимся понять силу и движение, чтобы они могли лучше понять окружающий мир.

- 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.
