- 24. the rate of speed with which something happens
- 25. physical power or strength
- 26. wrote the laws of motion
- 27. force equal in size and opposite indirection
Down
- 2. acceleration of an object depends upon mass of object and net force acting upon object
- 4. a rate of increase of velocity
