Fill in the blank. "____ is a force exerted by pulling on a string or rope that is connected to an object."
What is Tension
300
Definition: "_____is a force that twists an object.
What is Torsion
300
Name the 3 types of external forces
What is Applied force, friction and Elastic/spring force

Squishing the cotton ball temporarily changed the shape, however this took longer than the rubber band. Explain which is more elastic.
The rubber band is more elastic because it goes back to its original state faster than the cotton ball. Time is the factor here.

The Tacoma Narrows Bridge failed because of what internal and external force.
When a ball hits the ground, the ball applies an action force on the ground. The ground applies a reaction force and the ball bounces back.
