# Thrust

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Thrust or thrust force is a force that moves an object.  The equation and calculators for determining thrust is shown below.

### Thrust formula

$$\large{ F = \frac { \left( m v \right)_2 \;-\; \left( m v \right)_1 } { t_2 \;-\; t_1 } }$$

$$\large{ F = \frac { \left( m_2 v_2 \right) \;-\; \left( m_1 v_1 \right) } { t_2 \;-\; t_1 } }$$

Where:

$$\large{ F }$$ = thrust

$$\large{ m_1 }$$ = initial mass

$$\large{ m_2 }$$ = final mass

$$\large{ t_1 }$$ = initial time

$$\large{ t_2 }$$ = final time

$$\large{ v_1 }$$ = initial velocity

$$\large{ v_2 }$$ = final velocity
