Across
- 3. acceleration can be a this in speed
- 4. uniform circular motion is this acceleration
- 5. the total amount of momentum in an isolated system is conserved
- 12. describes both speed and direction of motion
- 13. this velocity is used to calculate acceleration. It is used second in the equation.
- 14. one way to describe the motion of an object changing speeds
- 18. the change in position of an object
- 19. the rate at which velocity changes over time
- 22. a graph that shows the distance covered by an object at regular intervals of time
- 24. a quantity defined as the product of the mass and velocity of an object
- 25. expressed in units of m/s
Down
- 1. an objects change in position relative to a reference point
- 2. acceleration can be determined using this type of graph
- 6. this force is the initial force applied in a pair; the force of a bat hitting a ball
- 7. combined velocities help to determine this
- 8. momentum is conserved in these
- 9. when a moving object collides with a non moving object momentum is
- 10. this velocity is used to calculate acceleration. It is used first in the equation
- 11. this can be related to a change in momentum
- 15. acceleration is this at which velocity changes
- 16. speed measurements involve this and time
- 17. acceleration can also be a change in this
- 20. this force is the reply to the initial force; the force of the ball hitting back on the bat
- 21. these types of objects have momentum
- 23. conservation of momentum can be used to explain how these work
