Across
- 4. Forces that occur even if objects are not in contact (gravity)
- 5. Act on an object as a result of interaction with environment
- 8. Forces do not act on the same line, but they do act through the same point
- 9. The process of determining a single vector from two or more vectors by vector addition (tip to tail)
- 10. Forces that have the same line of action and can be the same or opposite direction
Down
- 1. Force acting parallel to surface of object
- 2. Act within the object or system and hold together when acted on by external forces
- 3. ag= -9.8 m/s2
- 4. Force acting perpendicular to surface of object
- 6. Forces resulting from objects coming into contact (ground reaction force)
- 7. Single resultant force derived from the vector composition of all acting forces and determines the net effect of all acting forces on a body
