Q:

# What are the real-life examples of Newton's second law?

A:

Newton's second law states that the speed of acceleration of a moving object depends on the object's mass and the force being exerted on it. One instance of this is the understanding that it requires much more force to push a vehicle than to kick a soccer ball, for example.

Simply, Newton's second law represents the fact that the greater the mass of an object, the more force there is needed in order to move it. This explains why, for example, it requires one person to easily lift a box weighing five pounds but multiple people exerting more force collectively to lift a box weighing 100 pounds. Acceleration, or the speed of a moving object, can be calculated with the equation Acceleration = Force / Mass.

• A:

The concept of air resistance is related to Newton's second law of motion, which describes acceleration and force. Air resistance is a significant factor in how fast an object falls, according to this law.

The law of inertia states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The law of inertia is sometimes referred to as Newton's first law of motion.

Some examples of natural laws include but are not limited to the Laws of Thermodynamics (such as the law that states energy can be transformed from one form to another but cannot be destroyed or spontaneously created) and Newton's Laws of Motion (such as the law that states an object in motion will stay in motion unless acted upon by another force). Natural laws are determined by fundamental physical, chemical and biological forces of nature.
