Acceleration of Rocket
The acceleration formula for rocket propulsion can be derived from Newton’s second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
a = F/m
where,
- a is the acceleration
- F is the force
- m is the mass
The more detailed formula of acceleration for rocket propulsion is given as
[Tex]a = \frac{V_e}{m}\frac{\Delta m}{\Delta t} – g[/Tex]
where,
- a is acceleration of the moving rocket
- ve is the exhaust velocity
- m is mass of rocket
- Δm is mass of released gas
- Δt is time taken to release gas
- g is acceleration due to gravity
Factors Affecting Rocket’s Acceleration
The following are some of the variables that affect a rocket’s acceleration:
- Thrust-to-weight ratio
- Propellant mass fraction
- Aerodynamic drag
- Gravity losses
- Efficiency of propulsion system

Rocket Propulsion
Rocket Propulsion is the process of moving a rocket or spaceship through Earth’s atmosphere or into empty space. It is based on the idea that there is an equal and opposite response to every action, known as Newton’s third rule of motion.
The fundamental idea is to release mass from the rocket’s engine quickly in order to create a push in the opposite direction and move the rocket ahead. This mass can be solid or liquid propellants, or in the case of ion propulsion systems, even ionized gasses. In this article, we will learn in detail about Rocket Propulsion and working of rocket engines.
