Document Summary

Macroscopic objects with speed much less than 186,000 miles per second. Universal law of gravitation (applies to all objects with mass) As opposed to relativity and quantum mechanics. Relativity - speed of light is constant in all inertial reference frames. Quantum mechanics - for microscopic objects particle and wavelike behavior. Displacement - x(t) (t)v dx(t) (t) x. Dt v (t) dt (t ) x f (t ) t. We don"t actually know where the particle is at a particular time unless (t)dt v independent information is given. Velocity - tells how (speed/direction) displacement is changing (m/s) T initial initial interval, slope between two points on curve. = slope of the tangent line at that point dx(t) dt. Acceleration - tells how (speed/direction) velocity is changing (m/s^2) (t)a dv(t) (t) v. Dt a (t) dt (t)dt a v f (t ) (t ) tf. Dispelling misconception of deceleration and slowing down . Velocity is slowing down car moving .
