A force acts perpendicular to the direction of motion of a body. What is work done?

The initial speed of a body of mass 2kg is 5ms^(-1) A force acts for 4 seconds in the direction of motion of the body. The force time graph is shown in Calculate impulse of the force and also find the speed of the body . .

If a force is acting on a moving body in a direction perpendicular to the direction of motion what will be its effect on speed and direction of the body ?

What should be the angle between the direction of motion of a body so that the work done is zero ?

How is work done measured when, The force is inclined to the direction of motion of the body?

Force acting on a particle does some work only when force has a component along the direction of motion of particle, force has a component opposite to direction of motion of particle force has a component perpendicular to direction of motion of particle. IV. force is not able to move the particle. Which of the following statement(s)) is/are correct?

How is work done measured when, The force acts along the direction of motion of the body

Work is said to be done by a force acting on a body, provided the body is displaced actually in ay direction except in a direction perpendicular to the direction of the force. Mathmatically, W=vec(F). vec(c)=Fs cos theta , Whereas eenrgy is capacity of a body to do the work, power is the rate at which the body can do the work. P=(W)/(t)=vec(F).(vec(s))/(t)=vec(F). vec(upsilon) Both, work and energy are measured in joule and power is measured in watt. With the help of the comprehension given above, choose the most appropriate alternative for each of the following question : In the above question, work done by the resisting force is
