Study Notes

Kinematics

Kinematics is the study of motion
Distance is a scalar quantity, meaning it only has magnitude and not direction.
Speed is a scalar quantity.
Time is a scalar quantity.
Mass is a scalar quantity.
Temperature is a scalar quantity.
Energy is not a scalar quantity but is related to temperature.

Vectors

Vectors have both magnitude and direction.
Displacement is a vector quantity.
Displacement is measured from the origin to the final position of an object.
Velocity is a vector quantity.
Velocity is the rate of change of displacement.
Vectors are usually represented by an arrow, where the length of the arrow represents the magnitude and the direction of the arrow shows the direction of the vector.

Scalar vs. Vector

Distance is a scalar quantity, while displacement is a vector quantity.
Speed is a scalar quantity, while velocity is a vector quantity.
When calculating distance, direction is not important, only the total length travelled is considered.
Displacement considers the direction and the straight line distance between the starting and end point.
