Forces
Across
- 6. equal and opposite forces
- 8. to draw by a physical force
- 11. the force of attraction between all masses in the Universe
- 12. a universal force between any two charged objects
- 14. any two bodies in the Universe attract one another with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them
- 15. an object that has more electrons than protons
- 16. for a collision occurring between two objects, the total momentum of the two objects prior to the collision is equal to the total momentum of the two objects after the collision
Down
- 1. to force (something) to move away or apart
- 2. the quantity of motion of a moving object; expressed as the product of mass times velocity
- 3. the vector sum of all the forces acting on an object
- 4. the universal force of attraction acting between all matter
- 5. the force of gravity pulling an object down
- 7. a force you exert, push or pull
- 9. forces acting on the object that are not equal in opposite directions, resulting in a change in motion
- 10. an object that has more protons that electrons
- 13. a resistance force that opposes motion
