If the net work done on an object is positive, what can you conclude about the object's motion?

- The object is moving with a constant velocity.

- The object is speeding up.

- The object is slowing down.

- The object is at rest; its position is constant.

Since there is a positive work on an object, this directly indicates that there is an increase in Energy on the body.

Work can be expressed in terms of Force and distance as

W = Fd

Where,

F = Force

d = Distance

The force in turn is a description of how mass accelerates according to Newton's second law, that is

F = ma

The mass (m) remains constant, but the acceleration (a) is constant, which implies directly that there is a gradual change in the velocity of the object.

Therefore the correct answer is: The object is speeding up.

The work is positive so the energy of the object is  increasing so the object is speeding up

What can you conclude about objects' motion?

As we know that the work is the product of the force and the displacement

[tex]W=F\times D[/tex]

Where,

F = Force

D= Distance

And from newtons second law we can see that

[tex]F=m\times a[/tex]

Since here mass will be constant to there will be a change in the velocity that is acceleration in the body so the energy of the body will change

Thus work is positive so the energy of the object is  increasing so the object is speeding up
