Answer 3

What does "inertia" mean to you?

Answer 4

What are the basic premises of the First Law?

Answer 5

its b but you should probably learn this.

Answer 6

Please try again on "inertia." It has little or nothing to do with friction or gravity.

Answer 7

Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion.

Answer 8

motion

Answer 9

i think it d

Answer 10

no activity is happening this a way to apprehend it

Answer 11

Please go back and re-read, carefully, the selection I borrowed from the 'Net. Of the four given possible answers, which one fits in best with Newton's First Law? Please don't guess.

Answer 12

it will not move until force is put in to the equation

Answer 13

@mathmale can I tell them pleae??

Answer 14

"inertia" is closely related to "lack of motion." Three of the four answer choices involve motion; one does not. Which one does not involve motion? In other words, which answer choice characterizes "inertia?"

Mrs.A: If you can ask questions that would help saad choose the correct answer, fine. But do NOT "tell them the answer." Thank you.

Answer 15

If the ball sits motionless on the ground, it's not going to move unless an external force is applied to it. Compare this to Newton's First Law (see above).
