1 Thursday, April 9, 2015 Do Now: Greg is interested in building a rocket that will fly vertically the greatest distance. After research, he determines that the fins of the rocket have the greatest affect on altitude, but is unsure what shape is best. Identify the following elements of a proposed science experiment he could design to answer his question: – Question – Variables – Type of Graph?

2 Today’s Goals: Forces and Motion Review BINGO! We will stop occasionally to elaborate/expand/practice and discuss Winner (s) get a prize!

3 Words: Acceleration Force Newton’s First Law Newton’s Second Law Newton’s Third Law Velocity Friction Speed Speed-time graph Distance-time graph Gravity Unbalanced forces Balanced forces Net force F=ma Distance/time Motion Inertia Reference point Momentum Centripetal force Displacement Newtons Deceleration

4 Here We Go!

5 A push or a pull

6 Shows the change in an object’s location from its reference point over a period of time.

7 PAUSE and PRACTICE!

8 Unequal push or pull applied to an object that results in motion

9 The direction and speed of an object with motion

10 The combined amount of force acting on an object

11 PAUSE and PRACTICE!

12 An opposing force that acts to slow objects in motion, stop objects in motion or prevent motion

13 An object’s point of origin (where it starts) before motion; the ZERO on a distance-time graph

14 A graph that illustrates how fast/slow an object is moving over a period of time

15 PAUSE and PRACTICE!

16 Law of motion: there is a relationship between force, mass and acceleration; F=ma; the amount of force required to move an object increases as the mass of the object increases; the acceleration of an object decreases as its mass increases

17 Law of motion: for every action, there is an equal and opposite reaction

18 The natural tendency for an object to resist a change in motion

19 The formula for calculating speed

20 PAUSE and PRACTICE!

21 The amount of force required to make an object move or to stop an object in motion

22 The force that causes an object to follow a circular path

23 The change in an object’s velocity over a given period of time

24 PAUSE and PRACTICE! What is the car’s acceleration?

25 the equal amount of applied force and opposing force acting on an object that results in no motion

26 Law of motion: an object in motion, stays in motion and an object at rest stays at rest, UNLESS acted upon by an outside force

27 The formula used to calculate force; shows the relationship between force, mass and acceleration

28 PAUSE and PRACTICE!

29 The force of attraction between objects; pulls them together; increases as distance decreases; increases as mass increases

30 Negative acceleration; object’s speed is decreasing

31 How fast or slow an object is changing location over a given period of time (movement)

32 PAUSE and PRACTICE! 1.What is the Red runner’s average speed? 2.Which runner is slower?

33 The movement of an object; object changes location

34 How far an object moves away from its original location; NOT = distance traveled

35 The standard unit of measurement for force
