Elastic collision - Wikipedia Before collision Ball A: mass = 3 kg, velocity = 4 m s Ball B: mass = 5 kg, velocity = 0 m s After collision Ball A: velocity = −1 m s Ball B: velocity = 3 m s Another situation: Elastic collision of unequal masses The following illustrate the case of equal mass, Elastic collision of equal masses Elastic collision of masses in a system with a moving frame of reference In the limiting case
Momentum - Wikipedia Momentum is a vector quantity: it has both magnitude and direction Since momentum has a direction, it can be used to predict the resulting direction and speed of motion of objects after they collide Below, the basic properties of momentum are described in one dimension The vector equations are almost identical to the scalar equations (see multiple dimensions)
Collision - Wikipedia Collision is short-duration interaction between two bodies or more than two bodies simultaneously causing change in motion of bodies involved due to internal forces acted between them during this Collisions involve forces (there is a change in velocity) The magnitude of the velocity difference just before impact is called the closing speed
Coefficient of restitution - Wikipedia In physics, the coefficient of restitution (COR, also denoted by e), can be thought of as a measure of the elasticity of a collision between two bodies It is a dimensionless parameter defined as the ratio of the relative velocity of separation after a two-body collision to the relative velocity of approach before collision
Collision response - Wikipedia Models and algorithms for simulating collision and reactionIn the context of classical mechanics simulations and physics engines employed within video games, collision response deals with models and algorithms for simulating the changes in the motion of two solid bodies following collision and other forms of contact
Eulers laws of motion - Wikipedia Euler's second law states that the rate of change of angular momentum L about a point that is fixed in an inertial reference frame (often the center of mass of the body), is equal to the sum of the external moments of force (torques) acting on that body M about that point: [1][4][5] M = d L d t {\displaystyle \mathbf {M} = {d\mathbf {L} \over dt} } Note that the above formula holds only if
Three-body problem - Wikipedia The circular restricted three-body problem In the restricted three-body problem formulation, in the description of Barrow-Green, [4]: 11–14 two bodies revolve around their centre of mass in circular orbits under the influence of their mutual gravitational attraction, and form a two body system [whose] motion is known A third body (generally known as a planetoid), assumed massless
