Does work done depend on speed?
No, work done by force at any instant does not depend upon the velocity at that instant. Work is dependent on the force and displacement.
What happens to the body on which the work is done?
Work done on a body is equal to the increase in the energy of the body, for work transfers energy to the body. If, however, the applied force is opposite to the motion of the object, the work is considered to be negative, implying that energy is taken from the object.
Is always done on a body when?
a force acts on body to displace it. …
What is done on a body when?
work done on body =change in kinetic energy of the body.
When the force applied on a body is increased the work done on it?
It is clear that the work done is directly proportional to both force and displacement of a particle. (a) If the magnitude of the force applied is increased, then the work done will increase proportionally. (b) If the displacement of the body is reduced, then the work done will decrease proportionally.
What done by a body is?
Answer: Answer is a part that is work done by a body is negarive,positive or zero.
When work done on a body is negative?
The work done by a body can be negative when the force acts opposite to the direction of displacement. Work done by a force is positive if the applied force has a component in the direction of the displacement.
Can work done be in negative?
Work is a measurement of energy, so it may seem odd to think that a work can be negative — but it can! Work is how much energy is done by a force over a distance. If you try to stop the net from moving, you will apply a force in the opposite direction that the net is moving.
In which situation force is applied but no work is done?
if a person is pushing a wall so in that case he is applying force but the wall is not moving. if work is done then there must be some displacement but in the case mentioned above the wall is not moving hence no work is done.
What is difference between work done by a fuel and work done by a moving object?
Answer: work done by fuel is conversion of chemical energy into mechanical whereas work done by moving object is due to its displacement by the application of force.
What are the factors on which work done by an object depends?
Work done by a force depends on (i) magnitude of force (ii) magnitude of displacement (iii) angle between force applied and displacement .
What are two factors work depends on?
Answer: The work done on a body depends upon two factors: Magnitude of the force (F), and. The displacement through which the body moves (s).
What are the two factors that affect the work done on an object?
factors affecting the work done are :- 1. Force applied 2. Displacement 3. Angle between direction of force applied and direction of motion.
