Push-Away Problems definitions Flashcards

A principle stating that the total momentum of a closed system remains constant if no external forces act on it.

Physics problems where objects initially together move apart, often starting at rest, simplifying momentum conservation.

The speed at which an object moves backward after exerting a force on another object, such as a gun after firing a bullet.

Energy stored in an object when it is compressed or stretched, such as in a spring.

The energy an object possesses due to its motion, calculated as 1/2 mass times velocity squared.

A system where all forces are internal, ensuring momentum conservation without external influences.

Forces that act between objects within a defined system, not affecting the system's total momentum.

A measure of a spring's stiffness, denoted as k, in newtons per meter.

A quantity of motion of a moving body, calculated as the product of its mass and velocity.

Newton's third law stating that for every action, there is an equal and opposite reaction.

A defined collection of objects considered for analysis, where internal forces are considered for momentum conservation.

Forces acting on a system from outside, potentially altering the system's total momentum.

The distance a spring is compressed or stretched from its equilibrium position.

An equation representing the conservation of momentum, often simplified in push away problems.

An example of push away problems where objects move apart due to an internal explosion.
