Solutions to Homework Set #5 Phys2414 – Fall 2005
... We would like to solve for the frictional force to get the answer. Comparing the two equations above we can see that both equations have FN as the first term, but one is multiplied by cos θ while the other is multiplied by sin θ. In order to solve this system of equations, we have to eliminate FN . ...

... An important consequence of this law was the realisation that an object can be in motion without a force being constantly applied to it. When you throw a ball, you exert a force to accelerate the ball, but once it is moving, no force is necessary to keep it moving. Prior to this realisation it was b ...

Friction
... Be sure the surface of the track is clean. Finger prints, dust, or dirt will make your results unreliable. The motion detector can be used to find the speed, and the LoggerPro file Friction plots force and velocity. If you use it, don’t forget to zero the force probe. The drawing below shows how the ...

7-1 The Law of Conservation of Energy
... Let’s compare and contrast the energy approach with the force approach. Energy can be a very effective tool, because in many cases we only have to consider the initial and final states and we don’t have to worry about how the system gets from one state to the other. On the other hand, energy tells u ...

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.
