So how do rockets move in space? With a little help from Newton's third law and the conservation of momentum, of course.

Newton's second law is really the law of conservation of momentum written in another way. Objects will maintain their momentum until a force is applied, and that force will change their momentum.

The law of conservation of mass states that mass can neither be created nor destroyed. Interestingly, numerous ancient philosophers observed the knack for chemical and physical reactions to simply ...

That's where the phrase “conservation of angular momentum” comes from. The classic example of this is a spinning ice skater or someone spinning in an office chair.

Physics 601: Momentum. Season 2 Episode 601 | 29m 24s. Students learn to define, give the MKS units for, and calculate momentum. 02/06/2002 | Rating NR ...

The audience watched rockets launch and objects collide as they learned about mass, velocity and conservation of momentum. “We teach about momentum in simplified terms,” said third-year ...

The first law of thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy.
