## 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 :.

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.

What is the Kinetic Energy of a kg object that is moving with a speed of 15 2KE/m = v2 OR v2 = 2KE/m v2 = 2(14J)/17kg v2 = v = m/s. ANSWER.

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.
