A force is a push or pull. There are several types, including: applied (from person or machine), tension (from string or cable), gravity (between masses), normal (perpendicular to surface), friction (moving across a surface), thrust (from pushing something the other way), drag (resistance from air or other fluid), buoyancy (from displacing a fluid), and lift (on wings moving through air).

,1,Acceleration is the rate of change of velocity (a = Δv/Δt). The unit for acceleration is m/s/s, or m/s^2. Acceleration is a vector with magnitude and direction. If velocity and acceleration point the same direction, the object is speeding up. If velocity and acceleration point opposite directions, the object is slowing down. Changing direction is also a form of acceleration.

,1,An object's position specifies how far the object is from a reference point, and in what direction. The rate than an object's position changes is called velocity. Average velocity is calculated as change in position divided by change in time. Position and velocity are vector quantities. Average speed is calculated as distance travelled divided by time. Speed and distance are scalar quantities with no direction.

,1,Earth receives a spectrum of electromagnetic radiation from the Sun which peaks in the visible range. Some of this light makes it to Earth's surface and is absorbed. The absorbed light is converted to thermal vibrations of charged particles, which then radiate infrared light. Greenhouse gases in the atmosphere (including carbon dioxide, methane, and water vapor) absorb the infrared light and then re-emit it in random directions. Some escapes to space, and some remains trapped in the atmosphere. The greenhouse effect keeps Earth warm enough to be habitable. However, human activities are increasing greenhouse gas concentrations and are thereby affecting Earth's climate system. Solutions to this problem include solar, wind, and nuclear energy, which do not emit greenhouse gases during operation.

,1,A blackbody is an idealized object that absorbs all electromagnetic radiation (light) that shines on it. Blackbodies do not perpetually warm up as they absorb light because the accelerating charged particles inside them radiate their own light. The spectrum radiated by a blackbody depends only on its temperature. The hotter a blackbody is, the more intense its radiation is, and the shorter its peak wavelength is. The relationship between temperature and spectrum is used to estimate a star's surface temperature based on its color.

,1,Electrons only exist at specific, discrete energy levels in an atom. If an electron absorbs a photon with energy equal to the difference between two energy levels, the electron will transition to the higher energy level. The atom is then in an excited state. When an electron transitions to a lower energy level, it emits a photon with energy equal to the difference. Every element has a unique emission/absorption spectrum, making atomic spectral lines a valuable tool for identifying elements in distant astronomical objects.

,1,When light at or above a threshold frequency shines on a metal surface, electrons are emitted from the surface. This phenomenon is called the photoelectric effect. The photoelectric effect is evidence that light is quantized—light exists as discrete packets of energy called photons. The greater the frequency of the light, the greater the energy of its photons. A closely related phenomenon is the photovoltaic effect, which is the underlying mechanism of solar cells.

During gamma decay, an excited nucleus releases energy in the form of a gamma photon. Gamma radiation is high-energy electromagnetic radiation (light) which has a shorter wavelength and higher frequency than visible light. Gamma rays are ionizing radiation. The number of protons and neutrons in the parent nucleus does not change, so the identity of the daughter nucleus is the same as the parent, but in a lower energy state.

During beta minus decay, a neutron in an unstable nucleus transforms into a proton, releasing a high energy electron and antineutrino in the process. During beta plus decay, a proton in an unstable nucleus transforms into a neutron, releasing a high energy positron and neutrino in the process. Beta particles carry away energy lost by the nucleus and are ionizing radiation.

During alpha decay, a large, unstable parent nucleus becomes a smaller daughter nucleus. It does this by emitting an alpha particle, a clump of two protons and two neutrons (a He-4 nucleus). The nucleus's atomic number decreases by two, and its mass number decreases by four. The alpha particle is high-energy ionizing radiation—it travels at high speed because it carries away the majority of the energy lost by the nucleus during the decay.

,1,During radioactive decay, an unstable nucleus (the "parent") spontaneously changes to become a different nucleus (the "daughter"), emitting radiation in the process. The nuclear radiation emitted during radioactive decay is high energy, ionizing radiation. Nuclear radiation is potentially dangerous to living things but also has many beneficial applications. Types of radioactive decay include alpha, beta, and gamma.

,1,Predator-prey population cycles demonstrate how populations of predators and prey interact and influence each other's growth. In general, as predator numbers increase, the prey population declines, leading to a decrease in predators. Over time, the prey population may begin to increase, restarting the cycle. The example of the snowshoe hare and Canadian lynx shows how predator and prey populations can vary in relation to one another.

,1,The commutative and associative properties apply to addition, but not to subtraction. Rewriting subtraction as addition of the opposite is a superpower that suddenly lets us use the commutative and associative properties (without changing the value of the expression) in expressions that previously had subtraction involved.
,1,Graph addition and subtraction expressions involving negative numbers on the number line. When we add a positive number, we move to the right on the number line. When we add a negative number, we move to the left. When we subtract a number, we move in the opposite direction as we would to add the same number.
,1,Explore the claim that subtracting a number is the same as adding its opposite using number lines. We move to the right on the number line when we add a positive number. We move to the left on the number line both when we subtract a positive number and when we add a negative number. So which direction do we draw the arrow when we subtract a negative number on the number line?
,1,Use the properties of addition to strategically add and subtract fractions with negatives and unlike denominators. We can rewrite the subtraction as adding the opposite so that the addition properties will apply.
,1,Understand that we can commute and associate terms as long as we keep the signs with the terms. We can also apply the additive identity property and the additive inverse property.
,1,Use number lines to find missing numbers in subtraction equations with integers. Arrows to the left equivalently mean adding a negative number and subtracting a positive number of the same magnitude. Arrows to the right equivalently mean adding a positive number and subtracting a negative number of the same magnitude.
,1,Use number lines to find missing addends in addition equations with integers. When we add a positive value, we move to the right on the number line. When we add a negative value, we move to the left.
