1. 10-4-10 Day 22 Topic: Relating Xt to Vt graphs Objective: I will construct a Vt graph using the data from an Xt graph Starter: What would this xt graph look like as a motion diagram? Write the corresponding word description as well. x (m) t (s) 0 + - x How many sections? 1 2 3 1 2 3

2. Velocity Speed and velocity are used interchangeably when doing a calculation; velocity, however, is defined as speed with direction. Fastest Pitch Recorded? Maybe 105.1 miSept. 27, 2010 hour

3. xt Graph to vt Graph “the slope of the xt gives the velocity”

4. 0.5 1 1.5 2 2.5 3 3.5 43214321 V t

5. x (km) t (hr) x (km) t (hr) x (km) t (hr) x (km) t (hr) x (km) t (hr) x (km) t (hr) DIRECTION: Draw the corresponding motion diagram and write a written description for each graph #2 #3 #4 #6 #5 1.

6. Vocabulary Speed - the rate at which position changes Constant Speed - speed that does not change Instantaneous Speed - speed at a given moment Average Speed - total distance divided by total time Velocity - a quantity that specifies both speed and direction
