An object's momentum will change if there is a non-zero net external force acting on it. This assertion is true.
<h3>
</h3><h3>What is momentum?</h3>
The momentum is defined as the product of mass and the velocity of the body. It is denoted by the letter P. It occurs due to the applied force. Its unit is Kg m/s².
p=mΔV
If there is a change in the velocity there must be a force acting on the object.
If an object is acted on by a non-zero net external force, its momentum will not remain constant. is an accurate statement.
<h3>
</h3>
