Linear Motion
Linear motion, also known as rectilinear motion, refers to the motion of an object in a straight line with a constant velocity or changing velocity. In other words, the object moves in a single direction without any rotation or angular movement. Examples of linear motion include a train moving along a straight track, a car moving in a straight line on a highway, or a ball thrown in a straight line. Linear motion can be described mathematically using equations of motion, which relate the displacement, velocity, and acceleration of the object

\( \overrightarrow{d} = v_i \; t + \frac{1}{2} a\;t^2 \) (Displacement Linear Motion) \( v_i = ( \overrightarrow{d} \;/\; t ) - \frac{ 1 }{ 2 } \; a \; t \) \( t = \sqrt{ 2 \; \left( \overrightarrow{d} - v_i \; t \right) \;/\; a } \) \( a = 2 \; \left( \overrightarrow{d} - v_i \; t \right) \;/\; t^2 \) |

Symbol | English | Metric |
\( \overrightarrow{d} \) = linear displacement | \( ft \) | \(m \) |
\( v_i \) = initial velocity | \(ft\;/\;sec\) | \(m\;/\;s\) |

Velocity Linear motion formula |
||
\( \overrightarrow{v_f} = v_i + a \; t \) (Velocity Linear Motion) \( v_i = \overrightarrow{v_f} - a \; t \) \( a = \overrightarrow{v_f} - v_i \;/\; t \) \( t = \overrightarrow{v_f} - v_i \;/\; a \) |

Symbol | English | Metric |
\( \overrightarrow{v_f} \) = linear final velocity | \(ft\;/\;sec\) | \(m\;/\;s\) |
\( v_i \) = initial velocity | \(ft\;/\;sec\) | \(m\;/\;s\) |
\( a \) = acceleration | \(ft\;/\;sec^2\) | \(m\;/\;s^2\) |
