motion
Across
- 3. ω , rate of change of an angle with which an object that is moving on a circular path
- 4. instantaneous acceleration found by taking the derivative of the velocity function with respect to time in unit vector notation
- 5. magnitude of which is the time rate of change of speed. Its direction is tangent to the circle
- 7. motion of an object subject only to the acceleration of gravity
- 8. vector from the initial position to a final position on a trajectory of a particle
- 9. vector from the origin of a chosen coordinate system to the position of a particle in two- or threedimensional space
- 11. coordinate system in which the position, velocity, and acceleration of an object at rest or moving is measured
- 13. component of acceleration of an object moving in a circle that is directed radially inward toward the center of the circle
Down
- 1. vector sum of centripetal and tangential accelerations
- 2. elapsed time a projectile is in the air
- 6. velocity of an object as observed from a particular reference frame, or the velocity of one reference frame with respect to another reference frame
- 10. path of a projectile through the air
- 12. maximum horizontal distance a projectile travels
