## Rocket Meaning Physics | Formula, Equation – Laws of Motion

We are giving a detailed and clear sheet on all Physics Notes that are very useful to understand the Basic Physics Concepts.

Rocket Meaning Physics:
Rocket is an example of variable mass following law of conservation of momentum.
Thrust on the rocket at any instant,
F = -u $$\frac{d M}{d t}$$
where, u = exhaust speed of the burnt gases and $$\frac{d M}{d t}$$ = rate of combustion of fuel.
Velocity of rocket at any instant is given by v = v0 + u loge$$\left(\frac{M_{0}}{M}\right)$$
where, v0 = initial velocity of the rocket,
Mo = initial mass of the rocket and
M = present mass of the rocket.
If effect of gravity is taken into account, then speed of rocket
v = v0 + u loge$$\left(\frac{M_{0}}{M}\right)$$ – gt

Laws of Motion:
There are various laws in Physics that define the motion of the object. When an object is in motion whether it is linear or circular there is some force which is always imposed on it.
