Want this question answered?
The displacement of a body which occurs when force is applied on it is called work.
The word 'work' in physics is defined as the transfer of energy from one material body to another. It is a body's displacement in space caused by an external force resulting in motion. If a force is applied but there is no displacement or motion, then no work is done. Also work is not done if a force is applied perpendicular to the body's displacement. Work is expressed in units such as joules or foot-pounds.
I suggest "displacement and distance".
If you start walking on the flat ground, then the displacement is caused at right angles to the direction of your movement. In a way, the displacement does not take place in the direction of force applied by your shoulder. Hence, no work is done.
think its physics
Work is the transfer of energy from one physical body or system to another. It is summarized in the equation W (work in ergs or joules)=f (force)*d (displacement of the body). =============================== It can also be defined as the displacement by a body due to a certain amount of force acting on it.
Work is said to be done by a force if the point of application of the force gets displaced. Work is measured by the product of the force and the displacement component in the direction of the force. Hence W = F s cos @ @ is the angle between the force vector and displacement vector.
Net displacement is the distance of a straight line from the beginning point to the end point.
It is a product of force and displacement: Work = force x displacement
according to physics it will be zero work W=F.S (dot product of force and displacement) from vector algebra W= F*S*cos ( angle between force and displacement) W = F * S * COS (90) BUT cos(90)= 0 so W=0
displacement in time (physics SUVAT equations)
Dot Products in Physics denote scalar results fmo vector products, e.g Work = F.D = FDCos(FD) a scalar result from the dot product of two vectors, F Force and D Displacement.
