Across
- 3. anything thrown or shot through the air, follows a curved path
- 5. Friction where an object moves through fluid, meaning either a liquid or gas
- 6. How far an object has traveled
- 7. When an object changes position due to a reference point distance vs displacement
- 8. Rate of change of velocity occurs when object changes speed, direction or both
- 12. Friction-like force that opposes motion of objects that move through air(2 words)
- 14. friction in which two surfaces are not moving past each other
- 17. gravitational force exerted on an object
- 19. The force that opposes the sliding motion of two touching surfaces
- 20. Friction between a rolling object and the surface it rolls on
Down
- 1. Distance and object travels per unit of time, rate of change in position
- 2. distance and direction of an objects change in position from the starting point
- 4. When two or more forces act on an object at the same time(2 words)
- 9. speed that does not change
- 10. speed at any given point in time
- 11. Includes speed of an object and direction
- 13. Friction where two surfaces slide past one another
- 15. any two masses that exert attractive force on each other
- 16. A push or pull applied to an object
- 18. measure period of an action; units:sec, min, hr
