# One Dimension Kinematics

- Kinematics
- studying the motion of objects.
- Scalar
- a quantity that described by magnitude alone.
- Vector
- a quantity that is described by magnitude and direction.
- Distance
- a scalar describing the travel of an object. SI units = m. Variable = s
- Displacement
- a vector describing an object's change in position. SI units = m. Variable = s
- Speed
- distance per unit time. SI units = m/s.
- Velocity
- displacement per unit time. SI units = m/s. Variable = v
- Acceleration
- change in velocity per unit time. SI units = m/s
^{2}. Variable = a
