Forces

2. Law of Motion/ states that acceleration happens when a force acts on a mass
5. Force/ the force exerted by a compressed or stretched spring upon any object that is attached to it
6. Force/ equal forces acting on an object in opposite directions
10. Force/ a force that acts at a distance
14. the tendency of an object to resist a change in motion
15. Force/ decides how much we weigh
17. Force/ when charged bodies attract or repulse each other
19. Force/ the force that opposes the motion of an object and acts parallel to the surface with which the object is in contact
20. the speed and direction of a moving object

1. Law of Motion/ for every action there is an equal and opposite reaction
2. Isaac Newton/ English mathematician and physicist known for his laws of motion
3. force/ a push or pull on one object by another that is touching it
4. a push or pull
7. Forces/ forces that produce a nonzero net force, which changes an object's motion
8. Force/ a force that acts on a surface in a direction perpendicular to the surface
9. The force of attraction or repulsion of magnetic materials
11. Force/ the sum of all forces acting on an object
12. Resistance/ a type of frictional force that acts upon objects as they travel through the air.
13. Force/ the upward force that keeps an object immersed in or floating on a fluid
16. Law of Motion/ a body remains at rest or in motion with a constant velocity unless acted upon by an external force
18. Force/ the force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite ends
21. the interaction of electric currents or fields and magnetic fields.
