When light changes direction as it passes through a boundary.
The strength of the force in each direction between the earth and any mass is called the "weight" of the mass. The force is equal in both directions, which means that the weight of the mass on earth is the same as the earth's weight on the mass. The force acts along the line between the center of the earth and the center of the mass. The direction toward the center of the earth is customarily referred to as the 'down' direction, and toward the center of the mass as the 'up' direction.
When speed changes, the rate a which you are going (ex: 22 miles per hour) changes. Direction changes when the direction(ex: north, south, east, west) changes. Any change in speed or direction of motion is known as 'acceleration'.
A change in position in a certain amount of time is called motion.
If the light is entering from air or a vacuum, the light will slow down. The affect of this, if the light hits the glass at an angle, is that the direction of the light will change.
Plant roots have specialized cells called statoliths that can sense changes in the direction of gravity. When the direction of gravity changes, these cells direct the growth of the roots in a new direction to ensure that the roots continue to grow downward, towards the center of the Earth. This process is known as gravitropism.
The acceleration of a falling object is called gravity. A free-falling object has an acceleration of 9.8 m/s/s when going downward on Earth.
When electric current changes direction, it is called alternating current (AC).
The upward force on an object is a measure of the force exerted on it in the opposite direction to gravity. It is often called the normal force and counteracts the downward pull of gravity to keep the object from falling through a surface.
Terminal velocity.
Ampere
The change in direction of an object when a force is applied to it is called "acceleration." The acceleration of an object depends on the magnitude and direction of the force, as well as the mass of the object.
A ray of light changes direction when it gets out of the water, and into the air. This is called "refraction".A ray of light changes direction when it gets out of the water, and into the air.

An upward slant is known as an incline or ascent, while a downward slant is called a decline or descent. These terms are often used to describe the direction or angle of a slope or surface.
its called a monsoon
An electric current that changes direction is called an alternating current (AC). In an AC circuit, the flow of electrons changes direction periodically, typically at a frequency of 50 or 60 Hz. This is in contrast to direct current (DC), where the flow of electrons is constant in one direction.
