Q:

# What is an example of the law of inertia?

A:

One example of the law of inertia is that a package thrown from a plane will move as fast as the plane in the same direction. The law of gravity affects the package, and while the horizontal axis speed is the same as the plane, the vertical axis speed increases.

The law of inertia states that an object that is already moving will continue to move and the speed of the movement remains the same. The only factor that can change the speed or the direction is an unbalanced force. In a state of motion, all objects are able to resist changes.

Parallel force systems are those in which forces act in the same direction. The opposite of a parallel force system is a perpendicular force system, which is a system that has forces acting at right angles to each other.

When the acceleration of an object is zero and the velocity is positive, the object continues to move at a steady velocity in the same direction. The object cannot be changing direction because direction change results in non-zero acceleration.

Inertia is the tendency for an object to remain in motion or at rest unless it is acted upon by an outside force. In the field of physics, this concept is referred to as Newton's first law of motion.
