Across 2. horizontal distance a projectile will travel 7. a quantity that has direction and magnitude 8. a quantity that only has magnitude, for example speed 11. distance from your starting point 13. measured in seconds, hours, minutes 16. an object which the only force acting on it is gravity 20. F=ma

Down 1. more mass = _________ acceleration 3. the force of a surface pushing back upwards 4. always measured in newtons 5. is equal to mu times the normal force 6. property of an object that always stays the same, even on the moon 9. units of m/s/s 10. for every action there is an equal and opposite reaction 12. similiar to mass, a bowling ball has more of this than a ping pong ball 14. speed with direction 15. balance point on the object 17. an object doing this has an acceleration of -10m/s/s 18. the force of a rope, cable, or string 19. also called the force of gravity, equal to m*g
