A ball is launched (initial velocity v0 ) into the air directly up the inclined plane, launched at an additional angle β above the plane’s surface. (a) Draw the situation here, and roughly sketch a predicted path of the ball for some in ...

... You push a heavy car by hand. The car in turn pushes back on you with a force that is equal in magnitude and opposite in direction to the first force. Why don’t the forces cancel each other out making acceleration impossible? Ans. The forces act on different objects so they cannot cancel each other ...

... A roller coaster of mass m starts at rest at height y1 and falls down the path with friction, then back up until it hits height y2 (y1 > y2). An odometer tells us that the total scalar distance traveled is d. Assuming we don’t know anything about the friction or the path, how much work is done by fr ...

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.
