About this activity
A teacher-led 3D slow-motion force lab. For each everyday interaction the class sets the force arrows on the object first, then a slow-motion replay shows the forces and the change inside: internal forces, friction and elastic force, elastic and plastic changes, and action and reaction pairs.
What students learn
- Identify the external forces on an object (applied force, friction, elastic or spring force) and the internal force they cause (tension, compression, shear, torsion)
- Differentiate between temporary (elastic) and permanent (plastic) changes in an object's shape
- Represent an action force and its reaction force: equal, opposite, and on different objects (Newton's third law)
