CP Conceptual Physics Marking Period 3 Study Guide
Chapter 9 Topics (Work and Energy)
|
· Work (what is it?) · What is the unit for work? · W = Fd (calculate) · Power · What does it mean when one machine is more powerful than another? · What is the unit for power? · P = W/t (calculate) · Mechanical energy – what is it? · What are the two things that simple machines can do? · How many different kinds of lever are there? What is the difference between them? |
· What is kinetic energy? · What is the unit for kinetic energy? · KE = ˝ mv2 (calculate) · What is potential energy? · Name the different kinds of potential energy · PE = mgh (calculate) · Conservation of energy -Study conservation of energy in a pendulum -Study conservation of energy in a falling object · When is mechanical energy not conserved? |
Chapters 10,11,12 Topics (Rotational motion)
|
· What is rotation? What is revolution? · What is the difference between rotational speed and linear speed? · Factors that affect linear speed (ways to make it faster or slower) · Remember ladybug example: Linear speed vs. rotational speed · Centripetal force – what is it? · What kinds of forces can provide centripetal force? · What is the centrifugal force effect? Is it an actual force? (explain) · Torque – what is it? · What do you need to do to have the greatest amount of torque? · What is a lever arm? What kind of lever arm will produce the largest torque? · What is the best angle to apply force for maximum torque? |
· What does it mean when torques are “balanced?” · (See-saw problems) – F1d1 = F2d2 and m1d1 = m2d2 (you need to be able to solve problems with two masses, one is a certain distance away, how far away should the second be) · Center of mass/center of gravity – what are they? · When will an object topple? · Rotational inertia – what is it? · What will make a rotational inertia large? · Will an object with large rotational inertia spin more quickly or more slowly? · Which will win the race – a solid disc or a hollow sphere with the same mass and diameter? Why? |
Chapter 32 (Electrostatic force)
|
· Electrical charge ( + or –) · Who came up with the convention of + and -? · When do charges attract? When do they repel? · What does “conservation of charge” mean? · Understand Coulomb’s Law · Difference between conductors/insulators (how do electrons move in each?) · What is a semiconductor? |
· Charging by friction/contact/induction (what happens in each of these?) · What causes lightning? · Charge polarization in insulators (what happens?) · What is “grounding” of electric charge? · What is an electric dipole? |
CP Physics
MP3 Quarterly Study Guide
Chapter 4 – Newton’s Laws
|
· Newton’s Second Law · How are force and acceleration related? How are mass and acceleration related? · F = ma (calculations) · Newton’s Third Law · Identify action/reaction pairs · Calculate Weight (Fg = mg) on Earth and different planets |
· Calculate friction forces Fk = µkN Fs,max = µsN · Calculate µk and µs · Find normal force (N) · Is normal force always opposite the weight? |
Chapter 5 – Work and Energy
|
· Work – when is it being done?
