Monday, Dec. 7th 1 Bell-ringer: Discuss with your neighbor; 1.What is motion? 2.What is the difference between distance and displacement? Agenda: Bell-ringer Review and finish “Describing Motion” notes “Formula Triangle Formula” activity Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer. (S.7.PS.3) Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object. (S.7.PS.5) Apply Newton’s Third Law to design a solution to a problem involving the motion of two colliding objects. (S.7.PS.6) Objective:

Write title on page 49, “Describing Motion” Motion– occurs when an object changes position relative to a reference point. WRITE DOWN EVERYTHING!

Distance vs. Displacement Distance – how far an object has traveled. Displacement – distance and direction of an object’s change in position from a starting point. WRITE DOWN EVERYTHING!

Speed Speed – the distance an object travels per unit time – rate of change in position Avg. Speed (v) = total distance (d)/ total time (t) v=d/t WRITE DOWN EVERYTHING! Type of SpeedDescriptionExample INSTANTANEOUSSpeed at any given point in time Driving a car and looking down at speedometer AVERAGETotal distance traveled divided by total time Taking a road trip CONSTANTSpeed that does not vary Putting car in cruise control

Graphing Motion WRITE DOWN EVERYTHING! Motion of an object can be plotted on a distance-time graph. X axis  TIME Y axis  DISTANCE The slope of a line on a distance-time graph gives the speed of an object in motion. Y X Distance Time

Directions for “Formula Triangle Foldable” 1.Create a “Formula Triangle Foldable” to help you calculate speed, distance and time in following word problems. 2.Write the term and definition for each term under the flaps. 3.In the center of the triangle, write the equation for speed (you can find this in your notebooks). 4.The following page contains directions for the foldable, and speed word problems. 5.Glue triangle at the top of page 48, and speed word problems at the bottom of page Show me when you’re finished with your triangle and word problems to get points for the day.

Tuesday, Dec. 8th 7 Bell-ringer: Discuss with your neighbor; the answers to your “Speed” word problems. Agenda: Bell-ringer Go over answers to “Speed” word problems “Acceleration” notes Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer. (S.7.PS.3) Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object. (S.7.PS.5) Apply Newton’s Third Law to design a solution to a problem involving the motion of two colliding objects. (S.7.PS.6) Objective:

Write title on page 51, “Acceleration” Velocity– includes speed of an object and the direction of its motion. What is the difference between speed and velocity? Answer: Velocity includes direction where as speed does not. WRITE DOWN EVERYTHING!

Acceleration– rate of change of velocity Acceleration occurs when an object changes speed, its direction, or both. WRITE DOWN EVERYTHING!

Acceleration (m/s^2) = change in velocity (meters/seconds) time (seconds) *Note: Change in velocity = final velocity – initial velocity Acceleration formula: WRITE DOWN EVERYTHING! Calculating Acceleration

A plane takes off… A bike comes to a stop… The plane is speeding up The bike is slowing down so acceleration is positive. so acceleration is negative. WRITE DOWN EVERYTHING! Positive Acceleration Negative Acceleration

Wednesday, Dec. 9th 13 Bell-ringer: Discuss with your neighbor; 1.What is the difference between speed and velocity? 2.What is the formula for acceleration? 3.What are the two types of acceleration? Agenda: Bell-ringer “Acceleration” practice problems Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer. (S.7.PS.3) Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object. (S.7.PS.5) Apply Newton’s Third Law to design a solution to a problem involving the motion of two colliding objects. (S.7.PS.6) Objective:

“Acceleration” practice problems Complete “Acceleration” practice problems by the end of the period. Show me when completed for points! Glue onto page 50 or 52; depending where your notes end.
