Physics
Aball is rolling across a frictionless surface when it suddenly stops.
according to newton's first law, why is the following statement incorrect?
"the ball stopped because it was not hit with a strong enough force."
a.
each object has a limited amount of inertia, no matter how much force initially causes it to move.
b.
an object stops when it has no more potential energy to convert into kinetic energy.
c.
uniform motion continues in a straight line until the object in motion is acted upon by an external unbalanced force.
d.
force is the result of mass times acceleration, so it was the acceleration that was not sufficient to keep the ball moving.

Ответ:
You can learn it mathematically, F = m*a
Here, acceleration can have a finite value only if there is an unbalanced force, if the motion is uniform, it means, it's acceleration is zero and force is balanced so, it won't stop [only in frictionless condition]
Hope this helps!
