Q- What is the meaning of vice- versa?
what happens to Kinetic Energy if velocity is doubled ,can i have the formula with explanation now?urgent reply appreciated
As per the text book , Work is defined as :
Work is said to be done if the Force applied on an object causes the object to move in the direction of the Force
Now referring to : The Live Test Series for Test 5 Paper Q2 ) ... KINDLY RECHECK THE Answer..
Which of the following statements about the work done by a force is incorrect?
0% got it right!
Work done by a force is defined as the product of the force on a body and the displacement of the body along the line of action of the force. Therefore, it is not necessary that the body always moves towards the direction of the applied force. Even if a body moves opposite to the direction of the applied force, work is done by the applied force. This is because the displacement of the body is along the line of action of the applied force. In this case, the work done by the force is considered negative.
The correct answer is A.
a weight lifter lifts the weight against the force of gravity.so the weightlifter does work.
pls look this up in the video:
minute 00:20 to 00:24
a weightlifter lifts the weight against the force of gravity so the weightlifter does work

i had asked a question that 'what is the SI unit of work in MKS system?.expert Rahul has answered me that the ANS is 'joule',but when i asked the same question in the rigt hand side ask and answer,which is given in each and every chapter the answer that was given to me was "erg".why?
