point A to point B. A force (magnitude P = 2.0 N) acts on the block between A and B, as shown. Points A and B are 1.5 m apart. If the kinetic energies of the block at A and B are 5.0 J and 4.0 J, respectively, how much work is done on the block by the force of friction as the block moves from A to B? 1) -3.3 J 2) +1.3 J 3) +3.3 J 4) -1.3 J 5) +4.6 J 1) +96 1) 4.6 m/s 1) -3.3 J A 1.5-kg object moving along the x axis has a velocity of +4.0 m/s at x = 0.

using real life experiments such as the mass pulley system using the Atwood’s machine and using springs (2) in series and parallel to determine their spring constants and extensions when a mass is hanged from them. Newron’s second law states that the force on an object is directly proportional to the rate of change of momentum, which later gives the formula F =ma , m= mass and a is acceleration. Newton;s third law suggests that every action occurring on an object has an equal and opposite reaction when

My definition of momentum is Tenacity, force, and admiration. My current job is not secure. Despite, the fact that I have been working in broadcast news as a video editor for the past eleven years, receiving my masters in Media Design can start developing my strategy for career change. I have been searching for ways to maximize my talent and skill set to keep me current with technology. Technology changes so rapidly that if you don't keep up with it, it will pass you by. In my current career you

Centripetal Acceleration and Centripetal Force 1. What is the centripetal acceleration of a point on the perimeter of a bicycle wheel of diameter 70. cm when a bike is moving at 8.0 m/s? 2. A pilot is upside down at the top of an inverted loop of radius 3.20 x 103 m. At the top of the loop his normal force is only one-half his normal weight. How fast is he going? 3. The maximum force a pilot can stand is about seven times his weight. (This is his normal force.) What is the minimum radius of

Measurement of the moment of inertia of a flywheel A flywheel of radius R is set up on a horizontal axle of radius r. A string of length h is wrapped round the axle with a mass m tied to the end (Figures 1 and 2). The moment of inertia of the flywheel and axle is I. The flywheel is accelerated by the couple applied by the mass m. The mass is allowed to fall through a height h at which point the string leaves the axle. The velocity of the falling mass at this instant is v and the angular velocity

Learners’ Misconceptions of Forces at Key Stage 3 Introduction Children’s ideas of science are developed through science education, but also life experiences. These life experiences will provide learners with an idea of how the world around them works, whether this is right or wrong (Smith, diSessa, & Roschelle, 1994). Children may arrive at Key Stage 3 with deeply imbedded misconceptions of forces and motion that not only affect how they initially think about forces and motion, but also the way

simple harmonic motion of the acceleration due to gravity Introduction: A system undertaking simple harmonic motion (SHM) can be restrained very accurately. The period of the SHM depends both on the mass of the system and the strength of the force tending to restore the system to its equilibrium state). Oscillations are a common part of life, for instance the vibrations of a musical instrument which helps make sounds or the foundations of a car suspension which are assisted by oscillations.

Michael Xu The first thing I considered before creating my car was the wheel size that I would use. After a bit of research, I came to the conclusion that using large back wheels and small front wheels would be most effective. I got this idea from the unique looking drag racing cars that have small front wheels and large back wheels. The reason for this is because during acceleration, the large wheels at the back can take advantage of the weight transfer during acceleration. The wheels at the

Robin Hood Case Kevin Jackson Lander University ABSTRACT Robin Hood and his band of friends are facing an issue of sustainability. Sustainability is the capacity at which an environment can support those living in it. This describes the problem in this case because the bigger Robin Hood’s gang gets, the less resources there are to be spread amongst them. Robin Hood’s gang developed this issue because there are many people in the kingdom that do not support the king or his decisions. This is
