the reference point— is a vector. Velocity— Is speed in a given direction‚ and is also a vector. Acceleration— is the rate of change of velocity in a given direction (velocity/time). The unit in SI is metres per second per second‚ or ms-2. Is also a vector. • Motion can be ‘relative’‚ ie. taken from a different reference point. The determination of speed‚ and also velocity and acceleration depends on what it is measured to. • Speed and velocity can be both ‘instantaneous’ and ‘average’

Kinetic Energy- 5. Friction- occurs between your tires and the road‚ in your brakes when applied 6. Traction- the action of drawing or pulling a thing over a surface 7. Centrifugal Force- it is a reaction to the centripetal force necessary to hold an object at a fixed point 8. Centripetal Force- 9. Deceleration- 10. Force of impact- he speed or force of the object when it hit another object‚ upon impact Module 4: Signs‚ Signals & Pavement Markings 1. Explain the purpose of the following

Although the "new information" that changed Aberle et al.’s minds indicated that inbreeding was at least as dangerous as Bittles’s estimates imply‚ they rejected the possibility that primitive man recognized this danger. Law and instinct. In Sir James’s words‚ It is not easy to see why any deep human instinct should need to be reinforced by law. There is no law commanding men to eat or drink or forbidding them to put their hands in the fire. The law only forbids men to do what their instincts

1. Summarize advances over time in determining the age of the Earth‚ including the importance of the discovery or radioactivity. Herodotus counted layers of earth near the Nile River in 450 B.C.E. The Bible was used in the Middle Ages to compute the age of the Earth. The 18th and 19th centuries brought a more scientific look into determining the age of the Earth by studying the salinities of the oceans‚ the rates of sedimentation‚ and models of cooling of different materials in order to calculate
