Across 1. action on a body that causes change in motion.(Newtons) 3. a retarding force, acting opposite to the direction of motion of a body or object. 6. force perpendicular to a surface. Created where objects touch other objects. 7. force that occurs between two surfaces that are at rest with respect to each other 9. force that pulls or stretches a material 12. acceleration of an object is proportional to the net forecasting on it and inversely proportional to its mass 13. state of a system in which all forces are in balance 14. whenever one object exerts a force on another object, the second object exerts an equal and opposite force 15. sketch that isolates a single object and uses arrows to represent the strength and location of forces acting on the objects 17. property of matter that resists change in speed or direction. 18. for every action there is a opposite and equal reaction 19. Not having any weight. Without any gravity 20. group of related and interacting objects and influences that we choose to investigate. 21. is a property of objects that corresponds to how heavy an object is

Down 2. is a force which brings equilibrium state. It is considered to be the equal and opposite of the resultant force. 4. the region of space surrounding a body in which another body experiences a force of gravitational attraction. 5. combination of all the forces that act on a body 8. energy due to mass in motion. Measured in units of joules 10. the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration. 11. Inertia- property of matter that resists change in speed or direction. 16. downward-acting force created by gravity acting on the mass of an object
