<p>Momentum in Newtonian mechanics is the product of an object's mass and velocity. Mathematically, it is represented as $p = m v$, where $p$ is momentum, $m$ is mass, and $v$ is velocity.</p> Signup and view all the answers

<p>The unit of measurement for momentum in SI is the kilogram metre per second (kg⋅m/s), which is equivalent to the newton-second.</p> Signup and view all the answers

<p>Newton's second law of motion states that the rate of change of a body's momentum is equal to the net force acting on it. This implies a direct relationship between force, momentum, and the rate of change of momentum.</p> Signup and view all the answers

<p>In any inertial frame, momentum is a conserved quantity, meaning that if a closed system is not affected by external forces, its total linear momentum does not change. This conservation of momentum is significant in analyzing the behavior of closed systems.</p> Signup and view all the answers

<p>Momentum is also conserved in special relativity, and its conservation is represented with a modified formulation to account for the relativistic effects.</p> Signup and view all the answers
