Why does an object in motion stay in motion unless acted on by an unbalanced force?
2 answers:
An object in motion stays in motion unless acted on by an unbalanced force A) because forces are what stop and start motion
<h3>Further explanation </h3>In Newton's first law, it is stated that if the resultant force acts on an object of magnitude is zero, it can be formulated:
then the object tends to defend itself from its state.
or can be stated:
<em>An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force. </em>
So for objects in a state of movement, objects tend to move forever. Likewise, for objects in a state of rest, they tend to remain forever. The tendency of objects like this is called<u> inertia </u>
The size of inertia is proportional to mass, the greater the mass of the object, the greater the inertia of the object.
In objects with mass that move translatively, the object will maintain its linear velocity
<u>Forces are balanced</u> when all the forces act upon an object balance with each other
<u>Forces are unbalanced</u> when there is an individual force that is not being balanced by another force
So the object in balanced forces:
- 1. object at rest v = 0, a = 0
- 2. object at motion v ≠0, a = 0
Let see the answer choices
- A) because forces are what stop and start motion
If there is an unbalanced force, the object will tend to move from the rest position or the object changes its state of motion.
Statement is true
- B) because balanced forces can not exist in nature
Balanced forces can exist in nature for example. For example a person standing on the floor. There are two forces. The force of gravity and the floor for upward force, thus the person maintains its state (rest motion). So this condition is called a state of balance or balance.
Statement is false
- C) because motion is the inherent state of all matter
All matter is not only in a state of movement but also in a position of rest
Statement is false
- D) because motion, once begun, continues to accelerate
motion of object can accelerate or decelerate
Statement is false

Utilize the formula:
= Final Velocity (86 m/s)
= Initial Velocity (0 m/s)
a = acceleration (m/s²)
t = Time (100 seconds)
As a result,
86 m/s = 0 + (a)(100 seconds)
Using algebra, divide 86 m/s by 100 seconds:
86 m/s = 100a
a = 0.86 m/s²
Rounded to one decimal place: 0.9 m/s²
