Answer:
Newton’s second law of motion
Explanation:
The second law of motion gives the direct relationship between the force, mass and acceleration. Its mathematical form is given by :
[tex]F=m\times a[/tex]
[tex]a=\dfrac{F}{m}[/tex]
It is clear that when mass of the object increases, its acceleration decreases. So, a wagon accelerating more slowly once mass is increased while force remains constant is an example of Newton’s second law of motion. Hence, this is the required solution.
