... Equations of SHM These graphs can be represented by equations. For displacement: x = A sin 2ft or x = A sin t f is the frequency of the oscillation, and is related to the period T by f = 1/T. The amplitude of the oscillation is A. Velocity: v = 2f A cos 2ft = A cos t Acceleration: a = - (2f) ...

Newton`s Second Law of Motion
... push harder, is the change in motion smaller or larger? Do you think this is a direct or inverse relationship? 2. Assume that you have a bowling ball and a baseball, each suspended from a different rope. If you hit each of these balls with a full swing of a baseball bat, which ball will change its m ...

Chapter 1 Units and Problem Solving
... Answer: No. Gravity acts on the astronauts and the spacecraft, providing the necessary centripetal force for the orbit, so g is not zero and there is weight by definition (w=mg). The “floating” occurs because the spacecraft and astronauts are “falling” (“accelerating” toward Earth at the same rate). ...

A neutron star with angular speed 0=70.4 rad/s underwent such a glitch in October 1975 that increased its angula ...

When an object moves in one dimension (along a straight line) in the positive direction, and its velocity increases over time (it speeds up), its acceleration is positive. Now imagine that same car slowing d ...
