Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD What is the formula that defines velocity?

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD v=d/t OR v=Δx/t

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD If you divided the total distance an object traveled by the total time it was traveling, what would you be calculating?

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Average Velocity

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD What two factors affect an object’s terminal velocity?

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Mass and Surface Area. As mass increases, terminal velocity increases. As Surface Area increases, terminal velocity decreases.

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD How do you find the instantaneous velocity of an object using a position-time graph?

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Calculate the slope of the graph for a given time. Rise/run = distance/time

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Explain or draw what negative velocity looks like on a position-time graph.

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD A negative slope. The object is moving backwards along the number line (back toward the origin).

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD What formula is used to define acceleration?

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD a=Δv/t a=(v f – v i )/t

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD What is the standard metric unit of acceleration?

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD m/s/s OR m/s 2

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD What does a positive acceleration look like on a position-time graph? Daily Double!!!

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD A curved line in the shape of a smiley face, or bowl.

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD What does a negative acceleration look like on a velocity-time graph?

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD A negative slope.

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD What are the two ways an object can experience a negative acceleration?

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD 1) Speed up in a negative direction. 2) Slow down in a positive direction.

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD During which time interval(s) is the object stopped?

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Third 3

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD When is the object stopped, accelerating, and/or moving at a constant velocity?

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Stopped Constant positive Velocity Negative Acceleration

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD How fast is the object moving after 3 seconds?

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Instantaneous velocity = slope Slope = (5m-0m)/(2s-0s) 2.5 m/s

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Given the position-time graph shown, draw the velocity-time and acceleration-time graphs.

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Draw the velocity-time and acceleration-time graph of the following scenario. A bicyclist travels at a velocity of 20 m/s down a road, but then must slow down and stop at a cross-road.

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD All objects near the surface of the Earth fall at a constant acceleration of…

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD 9.8 m/s 2

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD What does Galileo’s Law of Falling Bodies state?

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD All objects fall at a constant acceleration (in a vacuum).

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD What causes there to be a constant acceleration of 9.8 m/s 2 ?

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Earth’s gravity

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD For the washer demo… if we wanted the time intervals to be equal, we would have to increase the distance between the washers following which pattern?

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD 1, 3, 5, 7, 9… The Law of Odd Numbers

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD A football is thrown straight up into the air. What are the football’s velocity and acceleration at its maximum height?

Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Velocity = 0 m/s Acceleration = -9.8 m/s 2
