Module 3: ROTATIONAL KINEMATICS Reference Book: Properties of Matter – Dr. Tofazzal Hossain MOMENT OF INERTIA: According to Newton’s first law of motion‚ “a body must continue in its state of rest or of uniform motion along a straight line‚ unless acted upon by an external force.” This inertness or inability of a body to change by itself its position of rest or of uniform motion is called inertia. Exactly in the same manner‚ in case of rotational motion‚ also we find that‚ a

CHAPTER 1 Graphs are used to study the relationship between 2 things so you can see what the relationship is. Unrelated: 2 items that are not associated. Ex. Hair color is unrelated to shoe size Directly related/proportional: 2 items that are associated such that when one item increases‚ the other increases. The graph of 2 directly related items extends from lower left to upper right. Ex. Clothing size is directly related to one’s weight. Related/ proportional: Is a relationship but can’t

THE FORCE OF GRAVITY Topics covered in this lab: Gravitational force Newton’s Laws One of the topics we have discussed is acceleration‚ meaning that the velocity of the object being studied is changing. What causes something to accelerate? In this lab you will investigate the forces that affect the motion of objects. Materials Something to toss Procedure Toss an object straight up into the air and catch it as it falls back down. Carefully watch the object’s vertical position

Evolution by natural selection is slow but can be observed in certain situations. How to spot evolution in real time: Artificial selection – manipulation by humans such as breeding dogs or growing corn. Repro-rate – rate of reproduction. Stochastic Event: unexpected disaster like a volcano eruption or tornado. (Research geological time) LIVING THINGS: Biology – Study of living things. Living things – all the organisms descended from a single-celled ancestor. * Characteristics:
