What is the work done by a force in moving an object in a circular trajectory?2 marksZero Depends on the mass of the object Double the force Half the force

A body of mass m is moving in a circle of radius r with a constant speed v. The work doneby the centripetal force in moving the body over half the circumference of the circle is

The work done by a force , applied to a point particle, when that particle moves, is:

A force of 2.45 N is applied to an object on a horizontal surface that causes it to move horizontally through a distance of 1.73 m. Correct to three significant figures, the total work done on the object is J.

State the equation linking work done, force and distance moved

In which of the following cases will work NOT be done on an object by the action of a force?When the object is moving very slowlyWhen the magnitude (size) of the force changes with timeWhen the force which is acting is small compared to the weight of the objectWhen the object does not move in the direction of the force2Which of the following will cause one joule (1 J) of work to be done on (energy to be transferred to) an object?A force of 1 N causing the object to move through a distance of 1 cmA force of 10 N causing the object to move through a distance of 10 cmA force of 100 N causing the object to move through 10 mA force of 5 N causing the object to move through 0.1 m3
