Across
- 2. - a measure of the amount of matter in an object
- 5. - a rigid bar resting on a fulcrum used to help move a heavy or firmly fixed load with one end when pressure is applied to the other
- 7. - stored energy; the energy an object has due to its position
- 10. - speed that stays the same and does not change
- 11. - the use of force to move an object over distances
- 13. - the object an observer uses to detect motion
- 15. - the amount of work an object can do because of the object's kinetic and potential energies
- 16. - the measurement of two positions; can either be a straight line or a measure of a path taken
- 17. - a wheel with a grooved rim that turns on an axle; used to lift loads
- 18. - a complete route in which an electric current can flow around
- 20. - a measure of the force of gravity on an object
- 23. - a change in velocity over time and how fast that change happened
Down
- 1. - a device that changes the direction or magnitude of a force that makes work more efficient
- 3. - two or more forces that are not equal and opposite of one another; can cause a change in motion
- 4. - speed in a specific direction (rate of change of an object's position)
- 6. - a push or a pull; something that changes the motion of an object
- 8. - a device that changes the force or increases the motion from work
- 9. - a tool used to plot how far an object moves over a given time; average speeds can be calculated from this
- 12. - the energy of motion. A moving object has the most kinetic energy at the point where it moves the fastest
- 14. - a force of attraction between objects that is due to their masses
- 15. - the change of position over time
- 19. - is the resistance of an object to a change in the speed or direction of its motion
- 21. - two or more forces that are equal and opposite of one another; do not cause a change in motion
- 22. - a force that resists the motion between two surfaces in contact
