Battleground 7th Physics

5. The interaction of electric currents or fields and magnetic fields.
9. Body Diagram A graphical illustration used to visualize the applied forces, movements, and resulting reactions on a body in a given condition (google.com).
10. The distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
12. The unit used for force (kg x m/s^2)
14. The formula for finding speed (a distance in a unit of time)
16. Forces The net force is not equal to zero. There will be an acceleration.
18. of Conservation of Energy Energy cannot be created or destroyed.
19. A force acting between two bodies that have mass, generally the center of the earth.
21. Any change in velocity (speed or direction)
22. The acceleration of an object is directly related to the mass of an object and the force applied.

1. An object's resistance to change what it is already doing (will not start moving if it is still)
2. A quantity that has both magnitude (size) and direction. Forces are vectors.
3. Speed and direction
4. Forces The net force is equal to zero. The velocity is constant (either moving at a constant speed in a straight line or at rest)
6. Isaac Newton English mathematician and physicist; remembered for developing the calculus and for his law of gravitation and his three laws of motion (1642-1727)
7. The rate of motion of an object
8. For every action there is an equal and opposite reaction.
11. The capacity for doing work existing in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms.
12. force The total forces acting on an object at the same time.
13. The formula used in Newton's 2nd Law.
15. circuit A closed circuit in which the current follows one path.
17. An object in motion will stay in motion, and an object at rest will stay at rest unless an unbalanced force is applied.
20. circuit A closed circuit in which the current divides into two or more paths before recombining to complete the circuit.
