Across
- 3. standard unit of energy and work
- 5. a missile designed to be fired from a rocket or gun.

- 22. the measurement of the change in an object's velocity. It is equal to the change in velocity over the change in time.
- 23. Machine, basic mechanical device for applying a force and doing work
- 24. resistance, describes the forces that are in opposition to the relative motion of an object as it passes through the air.
- 25. the splitting of an atomic nucleus

Down
- 1. a substance, body, or system that conducts electricity, heat, etc
- 2. fall, any motion of a body where gravity is the only force acting upon it.
- 4. force, a fictitious force that can be thought of as acting outwards on any body that rotates or moves along a curved path
- 5. measurement of the rate at which energy is used
- 6. of projection, the angle at which an observer draw an object to convert it from 3D to 2D plane such as real object image to a plane paper
- 7. a stable elementary particle present in all atoms
