The first semester of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an object, ...

Students learn to define, give the MKS units for, and calculate momentum. Momentum: Students learn to define, give the MKS units for, and calculate momentum and to use the impulse equation to explain ...

Segment 4B: Conservation of Momentum We explain it qualitatively and mathematically. Segment 4B: Conservation of Momentum The law of conservation of momentum is explained qualitatively and ...

For example, an elephant has no momentum when it is standing still. When it begins to walk, it will have momentum in the same direction as it is travelling. The faster the elephant walks, the larger ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it encompasses both the intrinsic spin of particles and their orbital motion ...
