Question

An object is moving with constant velocity. Which of the following statements is true?

A) The net force on the object is zero.
B) A constant force is being applied in the direction of motion.
C) There are no forces acting on the object.
D) There is no frictional force acting on the object.

Answer 1

C) There are no forces acting on the object.
That doesn't mean there aren't ANY forces acting on the object; it just means they are all canceling out. So there COULD be friction, but if there is, there's also some force that just matches the friction in the opposite direction.

Answer 2

If an object is moving at a constant velocity, it must not be accelerating. If it is not accelerating, but is at a constant mass (which it is), that must mean that it has a net force of zero acting upon it. It is possible for there to be no forces on the object, but it is also possible for forces to be acting upon the object and just cancel out. I do agree with whitekitten_cat that any forces acting upon the object are canceling out, but since it is still possible for forces to be acting upon the object that cancel out, I think the answer is A) The net force on the object is zero.

Answer 3

I had this question awhile ago but It is C.
But good observations

Answer 4

yeah i just typeed in a as my answer and the computer accepted it,so whitekitten is right

Answer 5

thank you. anymore ill help out. hey you think you can answer mine

Answer 6

what's urs

Answer 7

Write an equation for the circle with center (-4, 4) and containing the point (-1, 16). Use the ^ key for the exponents. Write your answer as the example: (x+2)^2+(y-9)^2=100

Answer 8

use the formula of the equation of a circle and solve,which is (x-h)^2 + (y-k)^2=r^2

Answer 9

i tried that

Answer 10

u substituted ur center into the equation?

Answer 11

yes

Answer 12

wat did u get as ur answer?
