Why does an object in motion stay in motion unless acted on by an unbalanced force?

ANSWER 1 - If an unbalanced force acts on an object in motion, then the velocity of the object will change. ANSWER 2 - The object will continue its state of motion. This property is called 'inertia'.

∙ 14y agobcoz there is no force 2 stop that object. let me give u an example:
think of Ice Hockey...if the player strikes the puck it will continue travelling for much much much further than if the puck was, say, on asphalt. the reason for this is the friction caused by the asphalt.
see if the object is acted upon by a BALANCED force, the resultant force is 0, bcoz the 2 (or more) forces cancel each other out

∙ 7y agoI don't think anybody knows WHY this is so; we only know that this is how our world works. If no force acts on an object (or if the sum of all forces is zero), then the velocity won't change. I don't think there is any way to PROVE that this is so; this has been observed by experiment.

∙ 7y ago"Constant velocity" means that the velocity doesn't change. Note that in physics terms, this means that the neither the speed nor the direction change.
"Unbalanced force" is the vector sum of all the forces acting on an object. As an example, if an object is resting on a table, gravity pulls downward on the object, while the table pushes upwards against the objects - the two forces are in balance (their sum is zero), and the object's velocity doesn't change.

∙ 7y agoThat is Newton's first law. It means that if an object is in motion (moving at constant velocity) it will stay at the same speed and direction (velocity) unless an unbalanced force acts on it. An unbalanced force is a force whose net force is not zero. If an unbalanced force acts on the object, it will accelerate in proportion to its mass (force = mass x acceleration, Newton's second law) and the object will no longer be at constant velocity

∙ 13y agoThe momentum of an object remains the same unless an unbalanced force acts on it! :D
Wiki User
∙ 13y agoThe reason is The Law of Conservation of Energy.
Force F =Derivative of Energy XE. When energy is conserved then F= ma=0 no force no acceleration. No acceleration no change in motion!
Wiki User
∙ 13y agoThat's right. This is described by Newton's laws of motion.

∙ 7y agobecause force imbalance will cause motion to accelerate and not be constant

What is Newton's first law of motion?
That law states that if no net force acts upon an object, that object's velocity won't change. For example, if it was at rest, it will continue at rest.Note that the First Law is a bit redundant - it is really only a special case of the Second Law, for the case that F = 0.
What is newton's second law of motion simplified?
an object in motion will stay in motion unless acted upon by another force
What will an object always do when acted on by an unbalanced force?
There's no such thing as "an unbalanced force". But when the entire group of forceson an object is unbalanced, then the object must accelerate.
What happens if an unbalanced force is applied to an object?
When an unbalanced force acts on an object, the weight of the object decreases.
What law of motion corresponds with the following statement?
What law of motion corresponds with the following statement? "A small car is easier to start moving than a large car."
Newton's laws 2 law of motion is?
an object at rest remains at rest unless acted on by an unbalanced force. an object in motion remains in motion unless acted on by an unbalanced force Hope this helps!!!
What does newton first law of motion say about object in motion?
The law states "An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force."
What does Newton's first law of motion say about object in motion?
The law states "An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force."
What does Newton's first law motion say about objects in motion?
The law states "An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force."
What does Newton first law of motion say about objects in motion?
The law states "An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force."
Which law of motion states that a body will not change its current state of motion unless an unbalanced force acts upon it?
Newton's 1st Law of Motion, often called The Law of Inertia. It states that an object at rest will remain at rest unless acted on by an unbalanced force. An object in motion will remain in motion with the same speed and direction unless acted upon by an unbalanced force.
What is the definiton of newton's first law?
An object in motion will stay in motion unless acted upon by an unbalanced force.
An object at rest will remain at rest and an object in straight-line motion will remain in straight-line motion unless acted upon by a(n) .?
...by an unbalanced force
What did newtons first law explain about motion?
An object in motion tends to stay in motion and an object in rest tends to stay in rest unless acted upon by an unbalanced force.
Newtons first law of motion defined in a few sentences?
An object at rest remains in rest, or an object in motion remains in motion unless acted upon by an unbalanced force.
What is Newtons first first law?
An object in motion will remain in motion or an object at rest will remain at rest unless an unbalanced force acts on it.
How does force affect an object's motion?
When a force is acted on an object the motion changes. Newtons 2nd law of motion states: An object in motion will stay in motion, and an object out of motion will stay out of motion, unless met with an unbalanced force. If a force is aplied to an object in motion it either accelerates, or it will stop once met with sed unbalanced force.
