What is the condition for a force to do work on a body?
Answer . How can a force be perpendicular to a point?! Surely you wanted to ask "Why no work is done when force is perpendicular to the direction of the displacement of th…e body?". This finds a simple answer in the definition of work: work done by a force F is defined as. W := â« F d r ,. where r is the position of the particle (that is, of the point of the body the force acts on), and hence d r is the direction of the displacement of the particle. From the definition, you immediatly see that if the angle between F and d r is 90Â° (or, in general, (2n + 1)Ï/2, with n element of Z) the scalar product is F d r = 0, and thus W = â«0 = 0.
Diseases, like pnemmonia, HIV, AIDS. crap like that.
The force must couple to the object.. The point of application of the force must be able to move in the direction of the force.
The sum of the vectors of the forces must be zero.
The equation of work is: Work = Fd * cos o As long as theta ^, the angle between the applied force, F, and the displacement, d, has value other than 90 degrees, or pi/2 (r…adians), then the force will do work.

Also, you nee…d to make sure you have the right/proper attitude when preforming you're job, towards the boss and towards you're co-workers.
Muscles produce forces by contacting their length. Forces can be turned into torques through the action of joints as pivots and bones as levers.
What are the conditions of equilibrium when number of parallel forces acting on the body. can a moving body be in equilibrium?
conditions for the equilibrium of parallel forces
Force Factor Supplement is one of the most liked supplements in the market. It is a very natural muscle growth stimulant. One can easily gain weight with the help of the Forc…e Factor. It has great content in the form of soya protein and nitric oxide which helps to gain weight and muscle. Force factor supplements are one of the greatest muscle gainers specifically designed for health conscious people.
When the net force that acts on a body is zero the forces are balanced this represents a condition called?
The formula says that work=force*displacement. Therefore the work will be zero if displacement is zero

Only if theone pushing had his or hers feet firmly against the side of theStation, would only one be pushed away.
