A woman steps in front of a child to keep him from running off. which term best describes this example? negative work positive work negative force positive force

Respuesta :

Answer:

negative force

Explanation:

Here woman is applying the force to stop the child or to prevent him from running.

Here we know that the force applied by the woman is opposite to the motion of child but here the child is not displaced by this applied force but the child is only prevented his running.

So here the work done by the woman is zero as there is no displacement by this force.

But here we can say that the the force of woman is against the motion of child so here this force is opposite force and hence it is termed as negative force here.

so correct answer will be

negative force

Answer:

Negative force.

Explanation:

Here the woman is applying a force to stop the motion of the child so the nature of force is negative. after applying the force child stops without any displacement means displacement is zero.

Since we know that

    WORK= FORCE * DISPLACEMENT

    WORK= FORCE* 0 (ZERO)

    WORK= ZERO.

means no work is done .only negative force would be the answer.
