Physical science
Across
- 2. A push or pull exerted on an object
- 3. the region around a magnet where the magnetic force is exerted
- 4. an attractive force that acts between any two objects
- 5. A place or object used for comparison to determine if an object is in motion
- 7. A simple labeled diagram that shows the forces acting on an object as arrows that indicate the magnitude and direction of the force.
- 8. to push away
- 9. Friction that opposes motion once the motion has already started
- 13. the region of space surrounding a body in which another body experiences a force of gravitational attraction
- 14. forces acting on an object that combine and form a net force of zero
- 19. opposes the motion of an object when an object moves through a fluid (e.g., gas, liquid)
- 21. a region around a charged object where the object's electric force is exerted on other charged objects
- 25. A material that allows heat and electricity to pass through it.
- 26. A measure of the extra positive or negative particles that an object has.
- 28. to pull toward
- 29. A measure of the gravitational force exerted on an object.
- 30. Energy caused by the movement of electrons.
- 32. not moving; not changing
- 33. the tendency of an object to resist a change in its motion
Down
- 1. Kinetic or potential energy associated with the motion or position of an object
- 3. the attraction or repulsion between magnetic poles
- 6. lines that map out the invisible magnetic field around a magnet
- 10. The overall force on an object when all the individual forces acting on it are added together
- 11. The force of attraction or repulsion of magnetic materials
- 12. size or numerical value
- 15. A force that one charge exerts on another. When the charges are the same sign, they repel; when the charges are opposite, they attract.
- 16. The distance an object travels per unit of time
- 17. A form of energy caused by the movement of electrons.
- 18. a device that converts electrical energy into mechanical energy
- 20. Change in velocity divided by the time it takes for the change to occur; the net force is greater than zero
- 22. A machine that converts mechanical energy into electrical energy
- 23. An object's change in position relative to a reference point.
- 24. temporary magnet that loses its magnetism when the electric current is turned off
- 27. one of the two ends of a magnet where the magnetism seems to be concentrated
- 31. the amount of matter in an object
