Mechanics is the study of motion forces and energy

discussion summary practice problems Mechanics is the study of motion, forces, and energy Summary Motionis the action of changing location or position. A forceis any interaction that causes a change in motion, shape, or energy. A system possesses energyif it has the ability to do work. (Work is done when a force causes a change in the energy of a system.) Mechanics can ...

relation of distance to displacement

discussion summary practice problems Summary relation of distance to displacement: Distanceis a scalar measure of the interval between two locations measured along the actual path connecting them. As a scalar it has magnitude only. Δs(italic) is the symbol for distance. Displacementis a vector measure of the interval between two locations measured along the shortest path connecting them. As a vector it must be stated with both magnitude and ...

Speed Velocity practice

 discussion  summary  practice  problems practice problem 1 Calculate the size of a light year. solution Astronomical distances are so large that using meters is cumbersome. For really large distances the light year is the best unit. A light year is the distance that light would travel in one year in a vacuum. Since the speed of light is fast, and a year ...
