define all the Newton's law of motion and linear momentum
Answers
Linear momentum(momentum of brevity) is defined as the product of a system's mass myltiplyed by its velocity Newtons second law of motion in terms of momentum states that the net external force equals the change in momentum of a system divided by the time over which its change.
Answer:
ok,
1st:
The first law states that , " An object continuous to remain at rest or state of uniform motion along the straight line unless an external unbalanced force act on it".
2nd:
" The rate of change of momentum is proportional to the applied force and the change of momentum is occurred in direction of force".
3rd:
"Every action force has an equal and opposite reaction force which acts simultaneously".
Linear momentum:
Linear momentum is a vector quantity definedas the product of an object's mass, m, and its velocity, v. Linear momentum is denoted by the letter p and is called “momentum” for short: Note that a body's momentum is always in the same direction as its velocity vector. The units of momentum are kg. · m/s.
