- 19. , is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to
- 20. a term that quantifies the overall effect of a force acting over time.
- 24. the resistance of any physical object to any change in its velocity. The tendency of inaction.

- 33. graph,the graph of velocity against time which shows how the velocity changes with respect to time.
- 34. is a surface or a line that is curved inward. In geometry, it is a polygon with at least one interior angle greater than 180°.
- 35. axis,a line that passes via the centre of the surface of a spherical mirror or lens and through the centre of curvature of all segments of the mirror or lens.
- 38. constant, Any one of the coefficients of the relations in the generalized Hooke's law used to express stress components as linear functions of the strain components. Also known as elastic constant.
- 40. length,s distance over which the parallel rays either converge or diverge.
- 44. momentum, It’s expressed as p=mv.
- 45. circuit,an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance
- 46. the change in direction of a wave passing from one medium to another caused by its change in speed.
- 47. line touching a curve at a single point without crossing it at that point.
- 50. is the point where light rays originating from a point on the object converge.
Down
- 1. with time of the position or orientation of a body.
- 3. thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system.
- 5. how close a measurement is to the correct value for that measurement.
- 7. Notation,6.5x10^8
- 9. Circuit,a circuit in which resistors are arranged in a chain, so the current has only one path to take.
- 10. Constant,the electric force constant, or the electrostatic constant is proportionality constant in electrostatics equations.
- 15. 3rd law, states that for a force applied by an object A on object B, object B exerts back an equal force in magnitude, but opposite in direction.
