... A car of mass 1000 kg travelling on a smooth road at 5.0 ms–1 collides with a truck that is stationary at a set of traffic lights. After the collision they are stuck together and move off with a speed of 2.0 ms–1 Q: How much momentum did the car transfer to the truck? A: Mom is ALWAYS conserved. Mom ...

Circular motion
... At any point in the motion of the object as it travels in the circle, the instantaneous velocity vector is tangent to the circle. And remember that at any point on a circle, the tangent line is perpendicular to the radius drawn to that point. So, in our diagram, the velocity vectors or perpendicular ...

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.
