### P: Physics

#### P.1: Motion and Forces

P.1.1: Newton's laws predict the motion of most objects.

P.1.1.1: When forces are balanced, no acceleration occurs; thus an object continues to move at a constant speed or stays at rest.

P.1.1.2: The law F = ma is used to solve motion problems that involve constant forces.

P.1.1.3: When one object exerts a force on a second object, the second object always exerts a force of equal magnitude and in the opposite direction.

P.1.1.4: Applying a force to an object perpendicular to the direction of its motion causes the object to change direction.

P.1.1.5: Circular motion requires the application of a constant force directed toward the center of the circle.

#### P.2: Conservation of Energy and Momentum

P.2.1: The laws of conservation of energy and momentum provide a way to predict and describe the movement of objects.

P.2.1.2: Changes in gravitational potential energy near Earth can be calculated by using the formula (change in potential energy) = mgh.

P.2.1.3: Momentum is calculated as the product mv.

P.2.1.4: Momentum is a separately conserved quantity different from energy.

P.2.1.6: The principles of conservation of momentum and energy can be used to solve problems involving elastic and inelastic collisions.

#### P.3: Heat and Thermodynamics

P.3.1: Energy cannot be created or destroyed although, in many processes, energy is transferred to the environment as heat.

P.3.1.1: Heat flow and work are two forms of energy transfer between systems.

P.3.1.3: The internal energy of an object includes the energy of random motion of the object's atoms and molecules. The greater the temperature of the object, the greater the energy of motion of the atoms and molecules that make up the object.

#### P.4: Waves

P.4.1: Waves have characteristic properties that do not depend on the type of wave

P.4.1.2: Transverse and longitudinal waves exist in mechanical media, such as springs and ropes, and in the Earth as seismic waves.

P.4.1.3: Wavelength, frequency and wave speed are related.

P.4.1.4: Sound is a longitudinal wave whose speed depends on the properties of the medium in which it propagates.

P.4.1.6: Waves have characteristic behaviors, such as interference, diffraction, refraction and polarization.

P.4.1.7: Beats and the Doppler Effect result from the characteristic behavior of waves.

#### P.5: Electric and Magnetic Phenomena

P.5.1: Electric and magnetic phenomena are related and have many practical applications.

P.5.1.3: The power in any resistive circuit element can be calculated by using the formula Power = I²R.

P.5.1.5: 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.

P.5.1.6: Changing magnetic fields produce electric fields, thereby inducing currents in nearby conductors.
