Modeliranje u znanosti sa Storyboard That

Oliver Smith

Modeliranje nam omogućuje da sami shvatimo što se i zašto se nešto događa. Konceptualni modeli su zajednički i eksplicitni prikazi ili analogije pojava, a znanstvenici ih koriste kako bi im pomogli da razumiju svijet oko nas. Modeli se koriste u svim područjima znanosti i nude vanjske verzije mentalnih koncepata. Modeli nisu savršeni prikaz; oni su pojednostavljena verzija sustava koji ističe neka područja, a druga ignorira.

Storyboard Tekst

• ﻿

• ﻿
• ﻿
• A rocket accelerating upwards
• ﻿
• ﻿
• ﻿
• ﻿Thrust
• A boat floating in the water
• ﻿
• ﻿
• ﻿
• ﻿Upthrust
• At the bottom of a bungee jump where the person is stationary
• ﻿
• ﻿

• Force from the Bungee Cord
• A person rappelling down the wall of a building with a rope
• ﻿
• ﻿Pull of the Rope
• ﻿
• ﻿
• ﻿
• ﻿
• ﻿
• ﻿
• ﻿
• ﻿Push from the Wall
• ﻿Friction
• 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.
• ﻿Weight
• ﻿
• ﻿
• ﻿
• Drag
• 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.
• ﻿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.
• ﻿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.
