Текст Раскадровки
- Горка: 1
-
- A rocket accelerating upwards
- Горка: 2
- A boat floating in the water
- Горка: 3
-
-
- At the bottom of a bungee jump where the person is stationary
- Горка: 4
- A person rappelling down the wall of a building with a rope
- Горка: 5

- Thrust
-
-
-
- Weight
- Drag
-
-
- The forces are unbalanced as the rocket is accelerating upwards. The thrust must be larger than the weight and the drag. The resultant forces have an upwards direction.
- Горка: 6

-
- Upthrust
-
- Weight
- The boat is stationary, so the forces are balanced. The upthrust and the weight of the boat must be equal in magnitude, but opposite in direction.

- Force from the Bungee Cord
-
-
-
-
- Weight
- The person at this point is stationary, so the forces must be balanced. This means the person's weight and the force from the rope must be equal in size, but opposite in direction.
- Горка: 8
-
- Pull of the Rope
-
-
-
-
-
- Friction
-
-
- Push from the Wall
-
- Weight
-
- The forces are balanced, as the person is not moving. The vertical component of the pull of the rope and the friction are equal and opposite to the person's weight. The horizontal component of the pull of the rope is equal and opposite to the push from the wall.
