(speed up/ slow down/ change direction)
Units: m/s2

9. What does it mean to do work in a scientific sense
What does it mean to do work in a scientific sense? Include unit for Work.
VAWP 300

10. Work is moving something in the direction of an applied force
(W= F x d)
Work is measured in Joules (J)

11. What is the formula for Power? Include unit for Power.
VAWP 400

12. Power = Work/ time
Unit: Watts (W)

13. VAWP 500
In the rod and reel Power Competition, Mikey reels up a 9.81 N weight a 1.0m in 6.44 seconds. What is Mikey’s Power?

14. P= W/t
W= F x d
F= 9.81 N
d= 1.0 m
t= 6.44 s
W= 9.81 N x 1.0 m = 9.81 J
P = 9.81J/ 6.44 s = 1.52 W

15. What is the combination of all forces acting on an object called?
Forces/ Friction 100

16. Net Force

17. Define Friction.
Forces/ Friction 200

18. The force that resists motion.

19. Give an example of Static Friction AND Kinetic Friction
Forces/ Friction 300

20. Static: Stationary/ Still/ At Rest
Answers Vary.
Static: Stationary/ Still/ At Rest
Kinetic: Moving

21. Contrast Balanced and Unbalanced Forces
Forces/ Friction 400

22. Balanced Forces:
Net Force = 0N
No Acceleration
Objects are stationary or traveling at constant velocity
Unbalanced Forces:
Net Force not equal to 0N
Acceleration
Objects speed up/ slow down/ change direction

23. Briefly define all of Newton’s Laws
Forces/ Friction 500

24. Law of Inertia- Objects at rest remain at rest/ objects in motion maintain velocity until unbalanced force acts on object
F=ma- The unbalanced force acting on object is equal to the object’s mass times its acceleration
Action/Reaction Pairs- For every action force there is an equal and opposite reaction force

25. Provide the formula and unit used for Gravitational Potential Energy
Heat/ Energy 100

26. GPE = mgh
Measured in Joules (J)

28. **remember to square speed/velocity FIRST!
KE = 1/2 mv2
Measured in Joules (J)
**remember to square speed/velocity FIRST!

29. How are Kinetic Energy and Temperature related?
Heat/ Energy 300

30. Direct relationship,
as KE increases, so does temperature/
as KE decreases, so does temperature

31. Explain the type and direction of heat energy transfer when you touch a hot cup of coffee.

32. Heat energy is transferred from high temperature to low temperature so direction is from the cup of coffee to your hand. You are in direct contact with the hot cup, so type of transfer is conduction.

33. Describe the 3 methods of heat energy transfer.

34. Conduction: Direct contact/ collision of particles
Convection: Movement of liquids or gases (fluids) in convection currents
Radiation: Transfer through waves/ no contact/ no movement of matter

35. Waves 100
