“9th Class Physics Chapter 6 Quiz: Work and Energy” is, in essence, a chapter dealing with the interrelation of work and energy within physical systems. For MDCAT students, this chapter is rather very important, since it introduces them to the concepts of energy conservation and the mathematical principles applied while computing work done and energy transferred. Our MDCAT Quiz for this chapter will help students consolidate their understanding and ensure they’re prepared for the exam.
The chapter first defines work as the transfer of energy that happens as a force acts upon an object to produce displacement. Work done by a force is given by the formula W = F × d × cos(θ), where W = work, F = force, d = displacement, and θ = the angle between the force and the displacement. Students will also learn about kinetic energy, the energy an object possesses as a result of its motion, and the formula K.E. = ½ mv². The chapter will also talk about potential energy, the energy stored in an object due to its position or configuration—most importantly, gravitational potential energy. Additionally, the chapter introduces the law of conservation of energy, which indicates that energy cannot be created nor destroyed, but rather transformed from one form to another.
