questions: force and motion I problem 1 The figure below is an overhead view of a 12 kg tire that is to be pulled by three ropes. One force (Fl‚ with magnitude 50 N) is indicated. Orient the other two forces F2 and F3 so that the magnitude of the resulting acceleration of the tire is least‚ and find that magnitude if (a) F2 = 30N‚ F3= 20 N; (b) F2= 30 N‚ F3 = 10 N; and (c) F2 = F3 = 30 N. problem 2 A weight-conscious penguin with a mass of 15.0 kg rests on a bathroom scale (see figure below).

Forces Have you ever wondered how forces link to our life? Everything we’ve learned in science has got me thinking about it. Forces are an essential part of our daily lives. Forces act on all objects. And we need force for everything we do‚ whether it’s a push‚ pull or twist. Force gives an object the energy to move‚ stop moving or change direction. Newton’s first law states that an objects velocity cannot change unless it is acted upon by a force. Here are examples of force in everyday life.

“give blood and save a life”. I didn’t know it yet‚ but those words were going to change my life. Over the next couple of days the school worked hard to promote the upcoming blood drive by putting up many posters and constantly reminding us over the loudspeaker every possible chance they had. I hadn’t given the blood drive much thought initially‚ but about a week prior to the designated date chosen for the blood drive‚ I was approached during lunch in the school cafeteria and was asked if I would like

FORCE AND MOTION Scalars vs. Vectors Scalars | Vectors | A scalar quantity has only magnitude. | A vector quantity has both magnitude and direction. | Scalars can be added‚ subtracted‚ multiplied and divided just as ordinary numbers‚ i.e.‚ scalars are subjected to simple arithmetic operations. | Vectors cannot be added‚ subtracted and multiplied following simple arithmetic laws. Arithmetic division of vectors is not possible at all. | Example: mass‚ volume‚ time‚ distance‚ speed‚ work‚ temperature

Centrifugal force Centrifugal force (from Latin centrum‚ meaning "center"‚ and fugere‚ meaning "to flee") is the apparent outward force that draws a rotating body away from the center of rotation. It is caused by the inertia of the body as the body’s path is continually redirected. In Newtonian mechanics‚ the term centrifugal force is used to refer to one of two distinct concepts: an inertial force (also called a "fictitious" force) observed in a non-inertial reference frame‚ and a reaction force corresponding
