Q1. Work is defined as the scalar product of force and displacement
... Two cars are initially at rest. Car A is at x = 0, and car B is at x = + 600 m. They start to move, at the same time, along the same line in the positive x direction with constant accelerations: a A = 4.00 m/s2 and a B = 1.00 m/s2. How long does it take car A to overtake car B? A) B) C) D) E) ...

... Thus, the torque on a particle changes the quantity ~r × p~. What is ~r × p~? It’s magnitude is |~r||~p|sinθ, where θ is the angle between ~r and p~. |~p|sin(θ) is the component of momentum perpendicular to ~r. It is in essence the ”rotational” momentum of the particle about the origin. The name giv ...

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
