PPT-Law of Inertia

Ms Ead Physics What Is the first law of Motion Station 1 Object in motion Object at rest An object at rest remains at rest and an object in motion remains in motion at the constant speed and in a straight line unless acted on by an unbalanced . The unit vectors 1 2 3 B e e e are fixed in the body and directed along a convenient set of axes pass ing through the mass center G The moments of inertia of the body about t hese axes are defined as 22 xx I y z dm 22 yy I x z dm 22 zz I x PHYS . 2010.

Moment of inertia. is the mass property of a rigid body that determines the . The Law of Inertia. The first law says that an object at rest tends to stay at rest, and an object in motion tends to stay in motion (with the same direction and speed) unless acted upon by an unbalanced force.. The lesson uses the Science Literacy Framework as the model for constructing the lesson. Sacramento Area Science . Project – Science Literacy Framework . ©. Entering the Content. Think about the statements in the . and rotational inertia. We consider the rotation of . rigid bodies. . A rigid body is an extended object in which the mass is distributed spatially.. Where should a force be applied to make it rotate (spin)? The same force applied at . Structural Member Properties. Moment of Inertia (I). is a mathematical property of a cross section (measured in inches. 4. ) that gives important information about how that cross-sectional area is distributed about a centroidal axis.. Conservation of rotational momentum. 1. Why does a wheel keep spinning. ?. Why . is a bicycle stable when it is moving, but falls over when it . stops?. Why is it difficult to change the orientation of the axis of a spinning wheel?. Structural Member Properties. Moment of Inertia (I). is a mathematical property of a cross section (measured in inches. 4. ) that gives important information about how that cross-sectional area is distributed about a centroidal axis.. Bus 374. Dr. Rajiv Krishnan Kozhikode. Structural Inertia and Organizational Change. Revisiting . Hannan. & Freeman’s (1977) arguments on inertia.. Inertia as an outcome of selection not a pre-condition for selection. Type of moment of inertia. Moment of inertia of Area. Moment of inertia of mass. Also known as second moment. Why need to calculate the moment of Inertia?. To . measures the effect of the cross sectional shape of a beam on the beam resistance to a bending moment. If you ride near the outside of a merry-go-round, do you go faster or slower than if you ride near the middle?. It depends on whether “faster” means . a faster . linear speed (= speed). , ie more . 1. st. Law of Motion. Inertia. An object will remain at rest or in constant motion unless acted upon by an unbalanced force. . “The Old Tablecloth Trick”. How does this comic relate to Inertia? . a = r. α. F = . mr. α. . Στ. = r .
