PHYS1131 Lecture Notes - Lecture 1: Apparent Wind, Mass, Cockroach
Document Summary
Introduce yourself to your neighbours and discuss some high school revision questions: Question 1: i drop a mass from height l, another from 2l. Does the second ball take less than twice as long to fall twice as long more than twice as long. Question 2: explain your answer qualitatively to your neighbour, without equations or values. Set &( = 0, )( = 0 and , = . (positive if s downwards). Given &$ = 0 and &" = 20. Question 4: i have a string with masses at heights 0, l, 2 l, 3 l, 4 l. i drop the string. Question 5: how do i space the weights so as to get equal times? i. e. we want. Distance fallen = & = $ where ! L is 0. 15 m. if only we could measure t we"d have g let"s try it.
