1. when work is done and a force is transferred which choice describes the movement of the object? (points : 3). a) when work is done and a force is transferred an object must move in the direction of the force.. b) when work is done and a force is transferred an object moves opposite the direction of the force.. c) when work is done and a force is transferred an object does not move.. d) when work is done and a force is transferred an object moves perpendicular to the direction of the force.

a) When work is done and a force is transferred an object must move in the direction of the force.

Explanation:

As we know that work done is given by the equation

W = F . d

now when work is done and force is transferred

then in that case the work done must be positive

so here we can say that angle between force and displacement must be acute angle

so here the displacement of object must be in the direction of the applied force so that the work done is positive.

So here correct answer would be

a) When work is done and a force is transferred an object must move in the direction of the force.
