Question

What kind of motion will an object have when forces on it are balanced?

It will move only slightly

It will start moving slowly then speed up

It will move very fast

It will not move at all



W7th grade science please help, Thanks:D

Answer 1

Alright, I'm gonna try to walk you through this problem.

Do you know what happens when you apply force on an object in one direction?

Answer 2

No i dont:(

Answer 3

Please help!:O

Answer 4

Sorry i just got what you said i was eating lol:)

Answer 5

Are you there?

Answer 6

Please help!

Answer 7

Ok. A Force is typically expressed in a unit called a Joule, which is the same thing as 1 kilogram times meter^2 divided by seconds^2.

Basically what this means to you is that Force, when applied to an object, will cause it to accelerate in a certain direction.

Make sense so far?

Answer 8

Yes so far lol....:D

Answer 9

Good!

Now, every force in our 3-D world can be expressed as a sum of forces that point vertically upward, straight forward, and to the side.

When you deal with multiple forces, you add them all up together in each direction.

What you have is the force in every direction = 0, right?

Answer 10

well sorda... Im not a very good learner im sorry! But i am starting to get what your saying you are helping me so much right now!:D

Answer 11

I'm here

Answer 12

Ok!:D

Answer 13

@Aylin. A force is not expressed in joules, but in newtons = kg.m/s²

Answer 14

So what is the answer?:D

Answer 15

So what it physically means when all of the forces on an object sum to 0 is that none of the forces will cause it to move in any direction. So whatever state it was in before all the forces acted upon it will remain.

For example, if it was moving to the right it would stay moving to the right at the same speed. Or if it was not moving at all, it will continue to not move.

Examples of the second thing would be a book on a table.

Answer 16

ohh ok:D What would the answer be than?:D

Answer 17

Yes, Vincent-Lyon is right, I wrote down the incorrect expression of units for force. However, it shouldn't change anything else I said.

Answer 18

An object with balanced forces acting on it will follow Newton's first law, also known as the Law of inertia : if it is at rest, it will stay at rest; if it is in motion, it will stay in motion with constant velocity.

Answer 19

ohh ok so the answer is it will move slightly than?

Answer 20

No, it will only be moving if it was already moving.

Answer 21

No, I'm afraid all answers are misleading.

The fourth one will be correct, provided the object is at rest in the first place.

Answer 22

so it will not move at all?

Answer 23

im confused what is the answer than?:D

Answer 24

That is unfortunately the closest answer.

Answer 25

* I was saying "no" to Jadehoff, not to Aylin

Answer 26

So i guess the answer would be it will not move right?

Answer 27

I agree with Aylin.

Answer 28

what one was the closes answer?

Answer 29

4th

Answer 30

3rd answer is also correct, if the initial velocity is high.

Answer 31

Ok thank you so much, You guys are very helpfull:D

Answer 32

Wait so witch one is the answer?

Answer 33

This question was written by someone who does not understand the Law of inertia, or who purposely wants to mislead the pupils !

Answer 34

I do flvs 7th grade This is my oral exam I am confused i just need tto knwo the answer lol:D

Answer 35

I have no idea what answer to choose;

Either none; or C&D together, depending on the initial motion of the body.

Answer 36

So what would be your closes answer tht you think is right?

Answer 37

If this is an oral exam, explain you are not satisfied with the answers, and that you would rather say that "the body will stay at rest if it is at restor will move at constant velocity if it is in motion."

Answer 38

im so confused.. lol

Answer 39

Are you there:(

Answer 40

I'm here. The closest answer is the fourth one, "It will not move at all", so if you /have/ to say one of them I would go with that one.

Answer 41

ok thank you so much:)
