Q:

# What is Newton's first law of motion?

A:

Newton's First Law of Motion defines the concept of inertia. The law states that an object will remain in its original state of motion until acted upon by an outside force.

Newton's Three Laws of Motion are used to define principles that are fundamental to the field of physics. First presented in 1686, these laws demonstrate the basic concepts that define the motion of all physical objects. The law of inertia contains implications regarding the symmetry of the universe; this can be applied to everything from the most basic movement of simple objects to more advanced concepts such as aerodynamics.

• A:

The law of inertia is a fundamental physics principle used to describe how an object behaves in motion or at rest, particularly when forces are applied to it. The object can be anything that has mass.

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.

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.
