Physics 111: Mechanics Lecture 3

Motion in Two Dimensions

  • February 5-8, 2013

Vector and its components

  • February 5-8, 2013
  • Or,

Vector Algebra

  • February 5-8, 2013
  • Which diagram can represent ?
  • A) B)
  • C) D)

Motion in two dimensions

  • February 5-8, 2013
  • y
  • x
  • z
  • i
  • j
  • k
  • x

Position and Displacement

  • February 5-8, 2013
  • In one dimension
  • In two dimensions
    • Position: the position of an object is described by its position vector --always points to particle from origin.
    • Displacement:
  • x1 (t1) = - 3.0 m, x2 (t2) = + 1.0 m
  • Δx = +1.0 m + 3.0 m = +4.0 m

Average & Instantaneous Velocity

  • February 5-8, 2013
  • Average velocity
  • Instantaneous velocity
  • v is tangent to the path in x-y graph;
  • February 5-8, 2013
  • A turtle starts at the origin and moves with the speed of v0=10 cm/s in the direction of 25° to the horizontal.
  • (a) Find the coordinates of a turtle 10 seconds later.
  • (b) How far did the turtle walk in 10 seconds?
  • February 5-8, 2013
  • Motion of a Turtle
  • Notice, you can solve the equations independently for the horizontal (x) and vertical (y) components of motion and then combine them!
  • X components:
  • Y components:
  • Distance from the origin:
