Kinematics
The study of motion without considering the forces causing it.
Two-dimensional kinematics
Deals with motion in a plane, considering both horizontal and vertical components.
Displacement
The change in position of an object.
\Delta r=r-r_{0}
Equation for displacement
Velocity
The rate of change of displacement.
Acceleration
The rate of change of velocity.
\overrightarrow{\overline{v}}=\dfrac{\Delta \overrightarrow{r}}{\Delta t}
Definition for average velocity
\overrightarrow{v}=\lim _{\Delta t\rightarrow 0}\dfrac{\Delta \overrightarrow{r}}{\Delta t}
Equation for instantaneous velocity
\overline{\overrightarrow{a}}=\dfrac{\Delta \overrightarrow{v}}{\Delta t}
Definition of average acceleration
\overrightarrow{a}=\lim _{\Delta t\rightarrow 0}\dfrac{\Delta \overrightarrow{v}}{\Delta t}
Equation for instantaneous accelerations

Projectile motion
The motion of an object that is launched into the air and moves along a curved path under the influence of gravity.
Relative velocity
The velocity of an object or observer with respect to another object or observer.
