WebIn fluid dynamics, drag (sometimes called fluid resistance) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between a fluid and a solid surface.. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag … WebThe kinetic energy of an object of mass, m moving with a velocity of 5 m s − 1 is 2 5 J. What will be its kinetic energy when its velocity is doubled? What will be its kinetic …

kinetic energy of a moving object is 100 joules. if its speed is ...

WebNote: The velocity of the object is doubled by changing the acceleration only. If the velocity is doubled its kinetic energy is multiplied by four times. And there is no … Web11.Discuss the motion of an object under free fall?
