Across
- 2. The point around which a lever rotates. E.g. a door hinge.
- 7. A system where both the vertical forces and the turning forces are balanced.
- 8. At an angle of 90o to a surface.
- 9. The product of an object’s velocity and mass. The more massive the object. The more momentum at the same speed. The greater the speed of an object, the greater the momentum.
Down
- 1. Keep the same.
- 3. A straight arm that rotates around a pivot. E.g. the handle of a hammer.
- 4. Another term for a pivot
- 5. A ‘plank’ or structure with negligible mass that is supported at both ends
- 6. Something with both Magnitude and Direction
- 9. A turning force or a rotational effect. The product of a force and the perpendicular distance from the pivot.
