How do you describe motion in words?
You can describe the motion of an object by its position, speed, direction, and acceleration. An object is moving if its position relative to a fixed point is changing. Even things that appear to be at rest move.
Which of the following helps us to see if something is moving?
When is an object in motion? An object is in motion if its distance relative to another object is changing. To tell if an object is moving, you use a reference point. If an object’s distance from another object [reference point] is changing.
Can a moving object be used as a reference point?
To decide if you are moving, you can use your chair as a reference point. An object is in motion if it changes position relative to a reference point. Objects that are fixed relative to Earth – such as a building, a tree, or a sign – make good reference points.

A frame of reference is defined as a reference point combined with a set of directions. For example, a boy is standing still inside a train as it pulls out of a station.
How do you find the reference point?
Calculate the reference number. The reference number equals pi – the terminal point. For example, if your terminal point = 5 pi / 6, your reference number = pi / 6. Pi would equal 6 pi / 6, and 6 – 5 = 1 or 1 pi / 6.
What is the meaning of reference number?

Are reference angles always acute?
Reference Angle: the acute angle between the terminal arm/terminal side and the x-axis. The reference angle is always positive. In other words, the reference angle is an angle being sandwiched by the terminal side and the x-axis. It must be less than 90 degree, and always positive.
Can reference points be inside the vehicle?
