1 Range of Projectile Motion - Department of Physics
AbstractThese lecture notes supplements my discussion class. We only haveone session per week and normally we have to rush through one wholechapter in less than 50 minutes. Now I believe supplementary notes arenecessary for you to further your understanding in Physics on your topic is independent. So you can just start with the section thatinterests you. Some topics are very basic, so I hope everyone will readthem. Others are advanced, which often exceeds the textbook level. So ifyou feel the course is too easy and you re bored, try challenging problemsI provide in these Range of Projectile Horizontal RangeMost of the basic Physics textbooks talk about the horizontal Range of theprojectile Motion . It is derived using the kinematics equations:ax= 0vx=v0x x=v0xtay= gvy=v0y gt y=v0yt 12gt2wherev0x=v0cos v0y=v0sin Suppose a Projectile is thrown from the ground level, then the Range is thedistance between the launch point and the landing point, where the projectilehits the ground.
the slope(The inclination is 20 )? 2 Choice of Coordinate System Before applying Newton’s 2nd law to a given problem, you need to x your coordinate system. We have one solid principle when we choose a coordinate system. Take one of the axes along the direction of acceleration. This is because
