Annotations:

  • Magnitude- a body's property that can be measured and it is used to study and describe them (2 TYPES)
1 Scalar Magnitudes
1.1 Definition: Scalars have values or have magnitude. However, it doesn't include direction.
1.2 Distance
1.2.1 A type of scalar measurement that only measures the length traveled.
1.3 Speed
1.3.1 A type of scalar measurement the rate at which someone or something is moving without direction.
1.3.1.1 Speed = Distance / Time
1.3.2 OTHER EXAMPLES: density, temperature, time, length, volume
2 Vector Magnitudes
2.1 Definition: Vectors have values or magnitude. They also include direction.

Annotations:

  • DIRECTION EXAMPLES: north, south east, west, northwest, northeast, southwest, southeast, left, right, up, down, inward, outward, returning to start, stationary, steady speed up, steady speed down. 
2.2 Displacement
2.2.1 A type of vector measurement that measures the length traveled and direction.
2.2.2 "AS THE CROW FLIES" is a term used (on a map) meaning the shortest distance back to the start point. This means instead of going around obstacles, you can go over them.
2.3 Velocity
2.3.1 A type of velocity measurement the rate at which someone or something is moving including direction.
2.3.1.1 Velocity = Distance / Time
2.3.2 OTHER EXAMPLES: weight, momentum, acceleration, force
2.3.3 Instantaneous Velocity or Speed

Annotations:

  • An instant of speed. When on a graph, the instantaneous speed is calculated by using ONE SEGMENT and use the speed formula.
2.3.4 Average Velocity or Speed

Annotations:

  • The overall speed of the ENTIRE graph. This means you calculate th TOTAL amount of distance and TOTAL time. Finally, you use the distance formula.
