Chapter 1 – Units, Scientific Notation, Significant Figures

Chapter 2 – Linear Motion

- solve problems that involve constant speed and average speed

Chapter 3 – Two-dimensional Motion

- how to resolve two-dimensional vectors into their components and calculate the magnitude and direction of a vector from its components

Chapter 4 – Forces and the Laws of Motion

- when forces are balanced, no acceleration occurs; thus an object continues to move at a constant speed or stays at rest (Newton’s first law)
- one object exerts a force on a second object, the second object always exerts a force of equal magnitude and in the opposite direction (Newton’s third law)
- to apply the law
*F=ma*to solve one-dimensional motion problems that involve constant forces - Newton’s laws are not exact but provide very good approximations unless an object is moving close to the speed of light or is small enough that quantum effects are important
- how to solve two-dimensional trajectory problems

Chapter 5 – Work and Energy

- how to calculate kinetic energy by using the formula
*E=(1/2)mv2*. - how to calculate changes in gravitational potential energy near Earth by using the formula (change in potential energy)
*= mgh*(*h*is the change in the elevation) - solve problems involving conservation of energy in simple systems, such as falling objects

Chapter 6 – Momentum

- calculate momentum as the product
*mv* - momentum is a separately conserved quantity different from energy.
- unbalanced force on an object produces a change in its momentum.
- solve problems involving elastic and inelastic collisions in one dimension by using the principles of conservation of momentum and energy
- solve problems involving conservation of energy in simple systems with various sources of potential energy, such as capacitors and springs

Chapter 7 – Rotation and Gravity

- relationship between the universal law of gravitation and the effect of gravity on an object at the surface of Earth
- applying a force to an object perpendicular to the direction of its motion causes the object to change direction but not speed
- circular motion requires the application of a constant force directed toward the center of the circle
- how to solve problems in circular motion by using the formula for centripetal acceleration in the following form:
*a = v2/r*

Chapter 8 – Rotational Equilibrium

Chapter 9 – Fluid Mechanics

Chapter 10 – Heat

- heat flow and work are two forms of energy transfer between systems.
- internal energy of an object includes the energy of random motion of the object’s atoms and molecules, often referred to as
*thermal energy*. The greater the temperature of the object, the greater the energy of motion of the atoms and molecules that make up the object.

Chapter 11 – Thermodynamics

- work done by a heat engine that is working in a cycle is the difference between the heat flow into the engine at high temperature and the heat flow out at a lower temperature (first law of thermodynamics) and that this is an example of the law of conservation of energy.
- most processes tend to decrease the order of a system over time and that energy levels are eventually distributed uniformly
- entropy is a quantity that measures the order or disorder of a system and that this quantity is larger for a more disordered system.
- to solve problems involving heat flow, work, and efficiency in a heat engine and know that all real engines lose some heat to their surroundings

Chapter 12 – Vibrations and Waves

- waves carry energy from one place to another
- to identify transverse and longitudinal waves in mechanical media, such as springs and ropes, and on the earth (seismic waves).
- solve problems involving wavelength, frequency, and wave speed.

Chapter 13 – Sound

- sound is a longitudinal wave whose speed depends on the properties of the medium in which it propagates.
- identify the characteristic properties of waves: interference (beats), diffraction, refraction, Doppler effect, and polarization

Chapter 14 – Light

*know*radio waves, light, and X-rays are different wavelength bands in the spectrum of electromagnetic waves whose speed in a vacuum is approximately 3 x 108 m/s (186,000 miles/second).

Chapter 15 – Refraction

Chapter 16 – Interference and Diffraction

Chapter 17 – Electric Forces and Fields

*know*how to solve problems involving the forces between two electric charges at a distance (Coulomb’s law) or the forces between two masses at a distance (universal gravitation).- charged particles are sources of electric fields and are subject to the forces of the electric fields from other charges
- the force on a charged particle in an electric field is
*qE*where**,***E*is the electric field at the position of the particle and*q*is the charge of the particle. - calculate the electric field resulting from a point charge.
*know*static electric fields have as their source some arrangement of electric charges- apply the concepts of electrical and gravitational potential energy to solve problems involving conservation of energy.

Chapter 18 – Electrical Energy

Chapter 19 – Current and Resistance

- solve problems involving Ohm’s law.
*know*plasmas, the fourth state of matter, contain ions or free electrons or both and conduct electricity

Chapter 20 – Circuits

- predict the voltage or current in simple direct current (DC) electric circuits constructed from batteries, wires, resistors, and capacitors.
- resistive element in a DC circuit dissipates energy, which heats the resistor. Students can calculate the power (rate of energy dissipation) in any resistive circuit element by using the formula Power =
*IR*(potential difference)*x I*(current) =*I2R*. - properties of transistors and the role of transistors in electric circuits.

Chapter 21 – Magnetism

- electric and magnetic fields contain energy and act as vector force fields
- magnitude of the force on a moving particle (with charge
*q)*in a magnetic field is*qvB*sin(*a*), where*a*is the angle between*v*and*B*(*v*and*B*are the magnitudes of vectors*v*and*B*, respectively), and students use the right-hand rule to find the direction of this force.

Chapter 22 – Induction

*know*magnetic materials and electric currents (moving electric charges) are sources of magnetic fields and are subject to forces arising from the magnetic fields of other sources- to determine the direction of a magnetic field produced by a current flowing in a straight wire or in a coil
*know*changing magnetic fields produce electric fields, thereby inducing currents in nearby conductors
