Document Summary

A communication system is described as consisting of a: sender, message, receiver. Scientific notation = contracted forms of a number. For scientific notation - how many times the decimal is moved to the left (is positive), decimal moves to the right if negative. Basic physical quantities (scalars): mass, length and time: magnitude only. Vectors: have 2 dimensions with both magnitude and direction (ex: displacement) Derived physical quantities (vectors) which have one or more components which are vectors are velocity and acceleration. Velocity- displacement that occurs over time: or time it takes to get from one place to another, v=d/t or x/t where x represents displacement, 1ms = 100 cm/s. Acceleration- change in velocity over time: a= v/t, 1 m/s^2 = 100 cm/s^2. Newton"s 3rd law: more force is needed to move an object with a larger mass, 10n< >20n = 10n to the right (if both pointing to the right, 30 n to the right)
