Newton's 2nd law state that the rate of momentum is proportional to the impressed force & the change in momentum takes place in the direction of force.
Mathematically ,
F = dP/dt = m dv/dt + vdm/dt = m dv/dt = ma [for constant mass system
dm/dt = 0]
Application:
In rocket propulsion, rocket propulsion represents a system of variable mass. This situation is analysed by generalising 2nd law to give result.
Thrust generated by leaving mass = urel dM/dt , where urel = velocity (relative) of detached mass w.r.t. parent mass and dM/dt = rate of change of mass
Hence a = urel dM/dt /Mo - dM/dt . t

What mechanics applies in outer space?
In outer space, objects follow Newton's laws of motion, which describe how forces affect the motion of bodies. There is no atmosphere in space, so objects do not experience air resistance. Gravity is the dominant force that governs the motions of objects in space, causing them to orbit planets or other celestial bodies.
What is the study of matter and energy and the interactions between the two through forces and motions is known as?
The study of matter and energy and their interactions through forces and motions is known as physics. Physics seeks to understand the fundamental laws and principles that govern the universe at both the macroscopic and microscopic levels.
What is the branches of a falling leaf according to physics?
When a leaf falls, it undergoes translational and rotational motion due to gravity. The translational motion is the leaf moving downward in a straight line, while the rotational motion involves the leaf spinning or twirling as it falls. These motions are governed by the principles of Newton's laws of motion and conservation of angular momentum.
What describes the motion of large bodies?
Large bodies, such as planets and stars, move according to the principles of celestial mechanics, which involve gravitation, inertia, and momentum. Their motion is primarily governed by gravitational interactions with other bodies and the overall structure of the universe. These movements can be predicted and explained using mathematical equations such as Newton's laws of motion and Kepler's laws of planetary motion.
Which Austrian scientist developed laws describing the motion of plantes?
Johannes Kepler, a German astronomer and mathematician, developed the three laws of planetary motion known as Kepler's laws. He used data collected by Danish astronomer Tycho Brahe to accurately describe the paths of celestial bodies.
What was galilao's contribution to science?
In physics, Galileo is remembered for discovering the laws of falling bodies and motions of projectiles.
Laws on motion of falling bodies and pendulum?
If you mean Newton's laws of motions, then they are: 1. A body in motion will continue unless a force is applied 2. Force equals mass times acceleration 3. For every action there is an equal and opposite force =)

Are planets of the solar system simply projectiles falling around the sun?
No, planets in the solar system are not merely projectiles falling around the Sun; they are in stable orbits due to the balance between gravitational attraction and their inertia. The Sun's gravity pulls the planets inward, while their forward motion keeps them from spiraling into the Sun. This dynamic creates elliptical orbits, as described by Kepler's laws of planetary motion. Thus, planets are in a continuous free-fall state, but they maintain a stable path around the Sun rather than simply falling toward it.
What are Three laws of motions?
The three laws of motion are: The Law of Inertia The Law of Acceleration and The Law of Interaction.

What of Kepler and or Newton and law best describes Aristotelian violent motions?
The laws of motion are described by Newton's Three Laws. These laws don't coincide fully with previous beliefs about motion.
