False
Question 3 (1 point)
•An object (even if it is not living) will resist a change in its state, either resting or in motion, this is called ____________.
Question 3 options:

force


mass


inertia


What is going to happen to this box?

box (The picture)

Question 4 options:

It will go up


It will go down


It will go to the left or right


It will stay where it is, because the forces are balance.

Question 5 (1 point)
Question 5 options:
The ______ of an object is a measure of its intertia.
.

Answer 1

1.true

2.false

3.mass

4.it will go left or right

5. force

Answer 2

1. False

2. True

3. Inertia

4. It will stay where it is, because the forces are balance.

5. Mass

Step-by-step explanation:

1. Law of gravitation is an example which states that two bodies exert force on each other which is equal to directly proportional to their masses and inversely proportional to the square of distance between their centers. So, even at distance, like sun and earth, bodies exerts force on each other so 1 is false.

2. This is Newton' s first law which states that every body will remain in its current state until an external force is applied. So balanced forces means zero net force, but unbalanced forces means non-zero magnitude of net force. So, 2 is true.

3. Inertia is a property of body to resist its current state of motion as defined by Newton's law. It is observable for mass at rest that it does not move until external force is applied. Similarly, moving body will always continue to move but on earth some opposite force cancels it like for rolling ball, their is friction and for ball thrown upward, their is gravity.

4. Since, forces are balance, so there is zero net force on body. Body will be at rest.

5. Mass is the measure of inertia and it resist the change in state. Newton's second law is F = ma

So, when force applied, mass is as constant quantity resist change in state of motion of a body. Since you can notice from the formula, that if mass is grater, there will be more force required to create acceleration.
