Work and Energy-MCQ
The unit of work is joule. A ball is dropped from a height of 10 m. How much time will be required to perform J of work at the rate of 20 W?
A students caries a bag weighing 5 kg from the ground floor to his class on the first floor that is 2 m high. Toggle navigation.
Work and Energy-MCQ. The other physical quantity that has same unit is. The spring will have maximum potential energy when. The energy possessed by an oscillating pendulum of a clock is.
The gravitational potential energy of an object is due to. If the velocity of a body is doubled its kinetic energy. The work done by the boy is. One unit of electrical energy is equal to.
Using the kinetic energy equation
Lesson 2 has thus far focused on how to analyze motion situations using the work and energy relationship. The relationship could be summarized by the following statements:. There is a relationship between work and mechanical energy change. Whenever work is done upon an object by an external or nonconservative force , there will be a change in the total mechanical energy of the object. If only internal forces are doing work no work done by external forces , there is no change in total mechanical energy; the total mechanical energy is said to be "conserved. Now an effort will be made to apply this relationship to a variety of motion scenarios in order to test our understanding. Use your understanding of the work-energy theorem to answer the following questions.
Work-Kinetic energy :. Determine the net work done on the car. Known :. Wanted : net work. Solution :. The work-kinetic energy principle :.

Physical Quantities and Measurement. Light energy. Electricity and Magnetism. Objective Questions. Q3 Match the following: Column A Column B a running water i energy b burning ii vibrations c energy iii atom bomb d sound energy iv kinetic energy e nuclear energy v joule.
Answer The energy possessed by a body due to its change in position or shape is called the potential energy. In classical mechanics, the gravitational potential at a location is equal to the work energy transferred per unit mass that would be needed to move an object to that location from a fixed reference location. It is analogous to the electric potential with mass playing the role of charge.

Kinetic energy , form of energy that an object or a particle has by reason of its motion. If work , which transfers energy, is done on an object by applying a net force , the object speeds up and thereby gains kinetic energy. Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. The kind of motion may be translation or motion along a path from one place to another , rotation about an axis, vibration , or any combination of motions.
Concept-Development Practice Page. We call this rule conservation of energy. Energy can be converted to different forms or transferred to different places but the total amount of energy does not change. Light and heat energy are given off from the light bulb to the air outside the bulb.
