This covers the main ideas upon what motion is, and terms related to it.

MOTION

1 Reference Point

1.1 A place or object, used for
comparison to determine if something is in motion

2 Motion is a change in position of an object with respect to
time also on its reference point. Motion is typically
described in terms of displacement, distance (scalar),
velocity, acceleration, time and speed.

3 International System of Units

3.1 The International System of Units is the modern
form of the metric system and is the world's
most widely used system of measurement.
Example: meter, centimeter, milimeter, decimeter

3.2 It is used to describe the distance an object moves. It is also used to describe
quantities other than length.

4 Speed

4.1 Equation: Distance/Time

4.2 It is the distance the object travels per unit of time.

4.3 Average speed: The average speed of an object in
an interval of time is the distance travelled by the
object divided by the duration of the interval

4.3.1 Calculate: Divide total distance travelled by the total time

4.4 Instantaneous Speed: instantaneous speed is the limit
of the average speed as the duration of the time
interval approaches zero.

5 Velocity

5.1 If both speed and direction of an object in motion is
given, then you know the velocity. It can also be said as
speed with direction

6 Acceleration

6.1 Acceleration refers to increasing speed,
or changing direction

6.2 Increasing speed: If the objects speed increases, it accelerates

6.3 Decreasing speed: The slowing down of an object, deceleration, is also acceleration

6.4 Changing direction: If the object travels at a constant speed, it is still accelerating. Objects can change their directions

6.5 Acceleration= Final Velocity-Initial Velocity/Time

7 Slope

7.1 Formula: Rise/Run

7.2 Steepness of a line on a graph is slope

8 Graphs

8.1 Line graph: The motion of an object can be shown in this graph where
you plot distance vs time

8.2 Speed-Versus-Time-Graph: The acceleration can be determined from the
slope/gradient of the graph. The steeper the gradient the higher the
average speed. A horizontal line indicates the object is moving at constant
velocity.

8.3 Distance-Versus-Time-Graph: The motion of an accelerating object can be
represented on it. It is usually a curve line and if the curve goes up it is
positive, whereas if it goes down it is negative
