If work done is a scalar quantity then why do we have positive and negative form of work? |
| Answer» Work done is a scalar quantity as it is a dot product of two vector quantities (W=F.S) , and dot product of any two quantities is a scalar quantity. Infact dot product is also known as scalar product. But since force and displacement are vector quantities they can be negative in value and hence work done can also turn out to be negative.<br>Work done is scaler quantity bcz dot product of two vector quantity is always scaler (W=F.D)<br>That what I m saying. It is vector quantity<br>I think work done is not a scalar quantity bcoz , It is product of force and displacement and these both are vector quantities....<br>you explain me in detail<br>R u sure work done is scaler quantity... Because W.D= force ×displacement... And displacement has direction and direction can be positive or negative... If u r confused than sry.. I can\'t able to give this answer. | |

Hiw to solve dmensions |
| Answer» For eg the formula of force ismaWhere (m) represent mass and(a) represent acceleration due to gravity Mass = MAcceleration due to gravity = velocity /timeWhere velocity =displacement /time Displacement is nothing but length So velocity =L/T where (L) represent length and(T) represent timeSo acceleration due to gravity =L/T/TSo the dimension of force( ma )= M^1 L/T^-2<br>For solving dimentions firstly we should know the formulas .Example:Area=length×breathWhere as , (breath is also one type of length)So, Area=length×length =length2Dimensinal formula =[M0 L2 T0]<br>I dont know | |
