Question

Which best describes Newton's first law?

Answer 1

A. A collision between a running back and linebacker in football
B. An ice hockey puck sliding along the ice after being hit by player’s stick.
C. A bowling pin being struck by a bowling ball.
D. A volleyball being “spiked” across the net.

Answer 2

is it b? it continued moving after it was hit???

Answer 3

Yes, 1st Law: An object will stay in motion unless acted upon by another force.

Answer 4

Newton's first law of motion - sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.-google-try thinking about your answer off of this :) its also explained better :)
@vaudriel giving direct answers is against the rules please read the CoC

Answer 5

Ok, but I still feel a little unconfident, what about C, the pin was at rest, then it was hit by an unbalanced force...

Answer 6

ok can you tell me on answer you would pick and why ?

Answer 7

ok, C, the pin was at rest (assuming) but then was stuck by bowling ball (unbalanced force)...

Answer 8

THats incorrect its B because it was hit so it continues moving a bowling pin get hit falls down

Answer 9

hehe my first choice

Answer 10

that's what I thought at first, but then I felt unconfident :(

Answer 11

oooh and yeah about the bowling pin.

Answer 12

yep I just wanted to make sure you understood it because it didnt seem like it :)

Answer 13

yeah, a little, I still needed more explaining :) thank you.

Answer 14

yep let me know if you need any help u can always tag me :)

Answer 15

ok so I know that the gravitational force between two objects increases if the mass increases and decreases if the distance increases, vice versa...

Answer 16

if the mass of one of the objects doubles, the gravitaional force doubles as well? I forgot by what ratio the GF increases

Answer 17

I'm reviewing for a physics exam lol and I kinda forgot :(

Answer 18

ok whats your question exactly

Answer 19

20) Object A and Object B have a gravitational force of attraction between them. Object A has a mass of 500 kilograms (kg), and Object B has a mass of 1000 kg. The two objects are 50 meters (m) apart. What will happen to the gravitational force of attraction between them if the mass of Object A doubles to 1000 kg and the distance between them remains the same?

Answer 20

repost it im not sire about that one
