Torques and Levers
... The lever systems of an animal set the relationships between force and speed (or distance). But, a high mechanical advantage and a high velocity ratio cannot occur simultaneously because the velocity ratio is the inverse of the MA. Thus, a high mechanical advantage and a high velocity ratio require ...

... 1. Draw the free-body diagram labeling all forces (their magnitudes and directions). Remember to use the appropriate positive and negative signs. 2. Add all the forces in the vertical direction. If the sum is zero, the forces are balanced, and there is no acceleration. If the sum is not zero, the f ...

Acceleration due to gravity
... When we use the word “acceleration” we mean the rate at which the velocity of a moving object changes with time. Acceleration is always caused by force – gravitational force as one of the fundamental forces of nature. This is the essence of Newton’s first law. In today’s lab we will measure the acce ...

... When the damping is strong such as shown here, two effects can be noted: • the decay factor exp{-t/T2} pushes the local extrema very slightly to the left, so that the effective angular velocity is lowered from ω0 to ω0- ∆ω0 (but this is not important) • the spectral analysis gives a broad lineshape ...
