Question

which laws are acting on the roller coaster?
○ all three laws: car keeps moving unless acted on, force of gravity causes acceleration, track pushes back on car
○ only newtons first law
○ only newtons third law
○ only newtons second law

Explanation:

Newton's first law (inertia) is seen as the car keeps moving unless a force acts on it. The force of gravity causing acceleration is Newton's second law ($F = ma$). The track pushing back on the car is an example of Newton's third - law (action - reaction). So all three laws are at play.

Answer:

All three laws: car keeps moving unless acted on, force of gravity causes acceleration, track pushes back on car
