Across
- 2. when distance decrease, gravitational force increases
- 3. force of attraction between objects due to their mass
- 5. A push or pull
- 7. force that resist of sliding surfaces
- 8. friction-like forces, opposes motion in a fluid
- 10. resist in change of motion
- 11. gravity increase with mass of each object
Down
- 1. forces that resist movement of two surfaces touches
- 4. combination of all forces
- 6. objects that travel around each other in space
- 9. where object experiences the forces
