Conceptual Physics Notes on Chapter 3 Motion in Two Directions
2
Vector and Scalar Quantities
Projectile Motion Vector and Scalar Quantities Scalar Scalar is just a number stand on a scale, it just tells you your weight Vector Vector is a number with a direction.
3
Projectile Motion Vector Addition +
A arrow is used to represent the magnitude and direction of a vector A velocity is sometimes a result of the addition or subtraction of vector quantities
4
Projectile Motion Components of Vectors
Any single vector can be resolved into two components Component vectors form right angles to each other a VERTICAL component of the velocity a HORIZONTAL component of velocity
5
See diagrams drawn on board
Projectile Motion Construct parallelogram to find the RESULTANT See diagrams drawn on board
6
Projectile Motion Any projectile has both vertical and horizontal components. This path a projectile follows is a parabola.
7
Projectile Motion Horizontal component of velocity stays constant
Vertical component of velocity has gravity acting on it --- so it changes in it’s path.
8
Projectile Motion Ideal path and actual path of a projectile are different We look a ideal path — NO air resistance If ideal --- then time up equals time down & velocity up equals velocity down
9
Projectile Motion Ideal Angle? 75" & 15" 60" & 30" 45" 90" & 0"
Pg 36 — what angle gives me the best distance Max horizontal and vertical components 75" & 15" 60" & 30" 45" 90" & 0"
