== Unit #2, Motion in One DIrection (One DImensional Motion) - TEST on Friday 10/22/10 - bring your calculator & use the scoring rubric on the wall to maximize your score!
==
Basic Equations for objects that move in a straight line are called Kinematic Equations.
Things to remember:
delta = change in something or delta = final value - initial value
Acceleration due to gravity is: 9.81m/s2 --> if going DOWN as referenced by you. Acceleration due to gravity is: -9.81m/s2 --> if going UP as referenced by you.Acceleration sideways (horizontally) is NOT due to gravity and must be either given or calculated!
HOMEWORK due Monday, 10/18/2010: A ball is thrown up into the air with an initial velocity of 30m/s.
1. How far did it travel in 1 second, 2 seconds, 3 seconds, 4 seconds, 5 seconds, and 6 seconds?
2. How fast was it going at these times?
3. Draw the ball being thrown into the air and draw the ball where it is at each of these times.
4 Make a plot of time versus displacement.
(Make sure you write your givens for each time. You will eventually do 12 calculations - 6 for displacement and 6 for final velocity. Make sure your drawing is drawn to scale reflecting the correct positions of the ball at each time. )
Here is an EXCEL program that will let you check your answer and see a sample plot of time versus displacement:
