Among the four fundamental forces, only one force governs your daily life almost entirely. Justify the statement by stating that force.

Explain applications of centrifugal force in our daily life?

If more than one forces are acting on a heavy rigid body such that the body is in balanced state, then all the forces are

State whether the following statement are True or False : The buoyant force due to a liquid is proportional to the acceleration due to gravity.

State whether the following statements are true of false with proper explanation: Use of energy is unavoidable in our daily life, but we must use it carefully and only in the required amount.

Choose the correct options At a given instant three point masses m, 2m and 3m are equidistant forces each other. Consider only the gravitational forces between them. Select correct statement//s for this instance only:

Answer the following questions: In the following case, state whether work is done or not. Justify your answer: Activity: One applies a force on a big rock but fails to move it.

State whether the following statement are True or False : Pressure due to a given force is directly proportional to the area on which the force acts.

This question has statement 1 and statement 2 . Of the four choice given after the Statement , choose the one that best describe the two Statement . If the spring S_(1) and S_(2) of force constant k_(1) and k_(2) respectively , are streached by the same force , it is found that more work is done on spring S_(1) then on spring S_(2) Statement -1: If statement by the same answer work done on S_(1) work on S_(1) is more then S_(2) Statement - 2 : k_(1) ltk_(2)

Fill in the blanks and complete the following paragraph . (words given: upward, friction,negligible,downward , gravitational , buoyance , very large, electric) When a body falls in air, there are three forces acting on the body : (1) the gravitational force due to the earth, acting........(2) the force of ........ due to air, acting .....(3) the force due to...... with air, acting in the direction oppositeto that of the velocity of the body. Under certain conditions, the force of buoyancy due to air and friction with air can be....... compared to the.......force of the earth. In that case (near the earth's surface) the body falls with almost uniform acceleration (g). Whenever a body moves under the influence of the force of gravity alone, it is said to be falling freely. Strictly speaking, this is true only if the body falls in vaccum.

State whether the following statements are True of False,Correct the false statement . Gravittional force at the Moon is double than the Earth's gravitational force.
