Wikipedia warns that the centripetal force is not to be confused with centrifugal force. It describes the latter as fictionious or inertial force. Decsribe an example of such a force that you have experienced and how this interaction might better be explained in terms of centripetal force.
Centripetal force is the force acting towards the centre of circular path but centrifugal force acts away from centre. While cycling there, when you are trying to turn in circular path, friction acting on the tires are centrifugal force. So fictionious forces are centrifugal force. When calculating the maximum velocity we use, we assume it as centripetal force = m*v^2/r=friction force. This is a situation where this interaction might better be explained in terms of centripetal force.

3. Distinguish between. centripetal force and centrifugal force. Explain in what direction each force t acting and on what it is acting. 32 4. Calculate at what speed the earth would have to rotate in ordet that objects at the equator would have n weight. Assume the radius of the earth to be 6400 kilometers. What would be the linear speed of a point o the equator? What would be the length of a day (time from sunrise to sunset)...
Physics 1 One of the main topics this week is circular, or centripetal, motion looking at its acceleration and associated force. For the centripetal force, is this a NEW force, explain? Often times, CENTRIFUGAL force is used in describing circular motion, is this an appropriate alternative to centripetal force, explain? One example of centripetal force is its application to curves - flat & banked - in terms of the maximum speed one can make the curve, what happens when the...
Draw diagrams that represents 1.Centripetal force, centrifugal force, radius, tangential velocity, the arc length, angular momentum angular velocity 2.What is torque? What equation represents it?! 3. When is torque the strongest and weakest? 4. At what angles is the torque is the strongest and weakest? 5. What is angular momentum? What equations represent this? 6. what is the moment of inertia for a ring? 7.Find the angular momentum from an object with a mass of 2kg, a radius of 8m...
(d) How is centripetal force produced? What is is direction? Can it be produced by non-uniform circular motion? If the circular motion is uniform (ie. the tangential speed is a constant), how does acceleration occur? (e) Define centrifugal force and indicate is direction What is is source? Which of Newton's Laws of Motion apply here? You may use a sketch to assist you in your answer. (I) Is a torque a scalar or a vector? If it is a vector,...
Does the force of gravity
alone provide the means for the centripetal force, is this why they
are equal ? For explaining why there is no normal force, could you
see it as the astronaut having the same acceleration as the ship
and so the relative acceleration = 0, so it's under the illusion
almost of having no acceleration so there's no force ? Please !! If
you have different reasoning please share. I'm just trying to wrap
my head...
The chapter describes how a market can be economically efficient. Before you took this class, you might have heard someone say that "markets are efficient." Compare and contrast the description of efficiency from the chapter to the definition of efficiency from physics: "Efficiency is a measure of how much work or energy is conserved in a process. In many processes, work or energy is lost, for example as waste heat or vibration. The efficiency is the energy output, divided by...
Discussion Questions Think about some of your friends and what you have discovered by visiting their homes. Do they buy different things than you do? If so, why? How might a company distinguish you from them in terms of its targeting? Is it always harder to find new customers than it is to retain old ones or does it depend on the business you're in? Does one-to-one marketing have to be expensive? How can small organizations interact with their customers...
How do plant roots impact and influence bone destruction? What is root etching? Describe the ways plant roots contribute to destruction of skeletal remains. Often root etchings are mistaken for vascular channels – how might you distinguish between the two? What about cut marks from sharp force trauma? What is acidic soil corrosion? What other taphonomic or destructive force on bone might acidic soil corrosion be confused with? How might you distinguish the two? What causes bioerosion of microscopic structure...
Consider the ladder in 8.15. Compute the normal force again,
assuming a 75 kg man is standing on the ladder (a) at its midpoint
and (b) four fifths of the way up the latter.
I posted this question earlier but was very confused on how it
was answered and laid out. I am not understanding how to go about
this or what formulas to use.
I know the answers is (a) 130.95 N and (b) 194.2 N but I do...
I need to solve this as a map please
Phvsics Concept Map Using terms in the tables below, or of your own creation, make a concept map that represents how YOU think the different ideas and concepts are related. List of guidelines: 1) Concepts are drawn in cither circles, rectangles, or boxes 2) Concept circles/boxes are connected by arrow lines. The direction of the arrow represents a rectionaiitv associated with the connection. Use a single arrow to represent a non-...
