Question

What does Newton's 2nd Law explain?

A. Why it is hard to pick up a very light object.
B. Why you must wear a seat belt.
C. Why you must push harder to move a car farther.
D. Why a ball keeps moving after it has been thrown.

Answer 1

Answer:

C. Why you must push harder to move a car farther.

Explanation:

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

$Acceleration = \frac {Force}{mass}$

Hence, Newton's 2nd Law explains why you must push harder to move a car farther because of its mass. Thus, it is important to increase the force that the engine provides and decrease the mass of the car.
