Abstract: The previous lab explored the effect of gravity on free fall. It was determined that acceleration is always constant under free fall. However‚ in this lab‚ acceleration was observed under different forces‚ other than just gravity. Therefore‚ depending on how strong the forces being exerted were‚ acceleration differed. It wasn’t constant anymore. Using a glider on a air track and a pulley‚ different masses were attached at the end of the string and the glider was allowed to move on the

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).

The electric field depicts the surrounding force of an electrically charged particle exerted on other electrically charged objects. The concept of an electric field was introduced by Michael Faraday. The electric field is a vector field with SI units of newtons per coulomb (N C−1) or‚ equivalently‚ volts per metre (V m−1). The SI base units of the electric field are kg⋅m⋅s−3⋅A−1. The strength or magnitude of the field at a given point is defined as the force that would be exerted on a positive test

They cause a shift in the equilibrium towards change change. i.e. A married couple who has to get ready for a party‚ the husband is on the couch watching the football game.

Competitive Forces (Porter’s 5 Forces) Analysis of the competitive environment can be done utilising Michael Porter’s 5-forces model of UPS and FedEx. Porter’s theoretical framework allows us to determine the overall profitability and sustainability within the industry (Laudon & Laudon 2006‚ pg.99; Hubbard 2004‚ pg.211). We reckon that in this case‚ the competitive forces for both UPS and FedEx are very similar because they are both in the same industry. Power of substitutes: Communications

the key characteristic of the U.S. Air Force became its airlift capability. Saying that‚ the Air Force became essential element in joint military operation supporting one of the joint functions such as sustainment. Sustainment gives necessary ability to joint forces to maintain and prolong operations until mission accomplished. Moreover‚ the ability of the Air Force to provide by air material and personnel in the theater of military actions gives to Joint Force Command (JFC) flexibility and the ability

Key External Forces External forces can be divided into five broad categories: * Economic forces; * Social‚ cultural‚ demographic‚ and environmental forces; * Political‚ governmental‚ and legal forces; * Technological forces; and * Competitive forces. Relationships among these forces and an organization are depicted in illustration below. External trends and events significantly affect

= 300g 9.8 3. Explain the effect of mass on Hooke’s Law. Hooke’s Law states that the restoring force of a spring is directly proportional to a small displacement. Applying a mass to the end of the spring stretches it‚ changing the length from its original equilibrium position of rest‚ to a new (lower) equilibrium position. At this position‚ the vertical restoring force of the spring balances the weight and the downward pull of gravity is balanced by the upward pull of the spring
