... At this point, there are two questions you should be wondering about: What is the definition of potential energy, PE, and why PEgrav = mgh, PEelastic = (1/2)kx2 ? Why is KE+PE = constant, when system isolated and no friction? It is not enough to know formulas. You should know where the formulas come ...

... A simple way to look at this concept is to think of the model of atoms which uses round spheres. The collisions of atoms are elastic collisions. An elastic collision is a collision in which the total kinetic energy of the colliding bodies after collision is equal to their total kinetic energy before ...

Net force
... • A block on a table may not start to move when we apply a small force to it. • This means that there is no net force in the horizontal direction, and that the applied force is balanced by another force. • This other force must change its magnitude and direction based on the direction and magnitude ...

How heavy is the car? 3) A car accelerates at a rate of 5 m/s2. If it weighs 500 kg how much driving force is the engine applying? 4) A force ...

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.
