Assertion: Decrease in mechanical energy is more in case of an object sliding up a relatively less inclined plane due to friction.Reason: The coefficient of friction between the block and the surface decreases with the increase in the angle of
Assertion: The work done against force of friction in the case of a disc rolling without slipping down an inclined plane is zero. Reason: When the disc rolls without slipping, friction is required because for rolling condition velocity of point of contact is
Kinetic Energy The energy possessed by a body by virtue of its motion is called kinetic energy. In other words, the amount of work done, a moving object can do before coming to rest is equal to its kinetic energy.`.^..' '` Kinetic energy, `KE =1/2mv^2` where, `m` is a mass and `v` is the velocity of a body.The units and dimensions of KE are Joule (in SI) and `[ML^2T^(-2)]`, respectively. Kinetic energy of a body is always positive. It can never be negative.An object of mass `10 kg` is moving with velocity of `10 ms^(-1)`. Due
Read each statement below carefully, and state, with reasons, if it is true or false;(a) During rolling, the force of friction acts in the same direction as the direction of motion of the CM of the body.
