Initial velocity, abbreviated as \(v_i\), is the starting point at which motion begins.
Initial Velocity Formula |
||
| \( v_i \;=\; v_f - a \; t \) | ||
| Symbol | English | Metric |
| \( v_i \) = initial velocity | \(ft\;/\;sec\) | \(m\;/\;s\) |
| \( v_f \) = final velocity | \(ft\;/\;sec\) | \(m\;/\;s\) |
| \( a \) = acceleration | \(ft\;/\;sec^2\) | \(m\;/\;s^2\) |
| \( t \) = time | \( sec \) | \( s \) |
Initial Velocity Formula |
||
| \( v_i \;=\; ( s \;/\; t ) - ( \frac{1}{2} \; a \; t )\) | ||
| Symbol | English | Metric |
| \( v_i \) = initial velocity | \(ft\;/\;sec\) | \(m\;/\;s\) |
| \( s \) = displacement | \( ft \) | \( m \) |
| \( t \) = time | \( sec \) | \( s \) |
| \( a \) = acceleration | \(ft\;/\;sec^2\) | \(m\;/\;s^2\) |
Initial Velocity Formula |
||
| \( v_i \;=\; \sqrt{ v_f - ( 2 \; a \; d ) } \) | ||
| Symbol | English | Metric |
| \( v_i \) = initial velocity | \(ft\;/\;sec\) | \(m\;/\;s\) |
| \( v_f \) = final velocity | \(ft\;/\;sec\) | \(m\;/\;s\) |
