Sonny and Manuel had to set up a demonstration to model one of Newton's laws. This is a photo of their demonstration. When Manuel hit the index card with his finger, the penny fell into the cup. Their demonstration modeled Newton's

Respuesta :

The answer is A) First law of motion.

Answer:

Law of inertia: Newton's first law.

Explanation:

This experiment can demonstrate Newton's first law which states "an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force".

In this case, the penny is at rest until Manuel exerts a force on the object, making it change its state of motion. So, basically, an external force is what made the penny to move and fall into the cup, if Manuel doens't exert this external force, then the peeny won't fall into the cup. That's Netwon's first law, the law of inertia.
