balance - centre of gravity - base - centre of mass - gravity - gravitational pull - gravitational force
In this activity, students witness a trick that appears to defy logic. By examining the object's centre of gravity and its base of support, the physics behind the illusion is unveiled.
The centre of gravity of the system (ruler + hammer) is the centre of the head of the hammer, which is directly below the tip of the ruler. As long as the table supports this point, the system stays balanced!
Students will be able to:
- Find the centre of gravity of an object.
