Which of the following is incorrect concerning Newton's First Law?
I know that Newton's first law states an object at rest will remain at rest as long as the net force on the object is zero.
I narrowed the questions down to three choices of the five:
A) An object can not have a constant speed if the magnitude of net force is greater than zero.
B) An object can not have a constant veloocity if the magnitude of net force is greater than zero.
C) None of the above.
I don't know why I'm having so much trouble with this question but any help would be appreciated!
Homework Answers
A) An object can not have a constant speed if the magnitude of net force is greater than zero.
is incorrect (in uniform circular motion , speed is constant)
B) An object can not have a constant veloocity if the magnitude of net force is greater than zero.
is correct ( due to acceleration velocity of the particle is change , in uniform circular motion , velocity is changes due to direction is change )

Part I - Newton's First Law Make sure the boxes that say “Force” and “Speed” are checked. a. Apply a force of 50 N right to the box. Describe the motion of the box using physics terms (i.e. velocity, acceleration, displacement). Refer to the speedometer in your answer. b. Reset the scenario (don't forget to check force, speed again). Apply a force of 50 N to the right for about 5 seconds then reduce the applied force to zero (the...
