Newton's Laws of Motion
Newton's second law of motion is F = ma, or force is equal to mass times acceleration. Learn how to use the formula to calculate acceleration.
Learn about Newton's third law of motion, which states that for every action there is an equal and opposite reaction. Look at multiple examples that illustrate this law, including pushing a block on ice, pushing against a desk, walking on sand, how rockets work, and how an astronaut could save themselves from drifting in space.
You want a projectile to fly as far as possible, at which angle should you launch it? We'll start with formulas for the initial velocity.
Osmosis is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. Osmosis helps regulate the flow of water in and out of cells, which is crucial to their function.
How homologous chromosomes separate into two sets. Prophase I, metaphase I, anaphase I, and telophase I.
Meiosis is a process that creates sex cells (gametes) with half the number of chromosomes of the parent cell. Meiosis has two stages: meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material (crossing over). In meiosis II, sister chromatids separate, creating four haploid cells.
The Calvin Cycle or the light-independent (dark) reactions of photosynthesis.
This video explains how pie charts can be used to display data in a more 'user-friendly' way.
