Chapter 1- Kinematics Regents Physics
Intro to Kinematics
Kinematics is the mathematical treatment of the motions of bodies without regard to the forces that produce the motion.
Scalar Quantities vs. Vector Quantities
4029075747395 A scalar quantity has magnitude but not direction . For example, the odometer in your family car tells you how fast the car is moving (magnitude or numerical value) but not the direction it is moving . Therefore, the odometer is telling you a scalar quantity (in this case: speed). For example, it tells you 45 mph, but NOT 45 mph East .
Here are some examples of scalar quantities:
A vector quantity has both magnitude and direction. For example, if you ask for directions to the beach in a foreign country, a citizen may tell you 50 km East . The citizen has given you both a magnitude (numerical value) and a direction (North, South, East, West, etc.)
Here are some examples of vector quantities:
206692538735 Electric Force
Practice: Determine whether the following are vectors or scalars.
40 m/s East
40 o C
20 kg(m/s) Northeast
25 N West

The Ice AgeThe Ice Age Twenty thousand years ago during the time of the last ice age period, many colossal mammals roamed North America. They survived during the times when much of the earth was covered by immense large bodies of ice that buried forests, fields, and mountains, but rapidly became extinct after the ice began to retreat and melt. Since then the human race has introduced many different theories to explain the extinction of these large mammals. One theory stands above all and explains the truth
