Study Notes
High School Science Curriculum Summary
- Newton’s second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
- Balanced forces result in no acceleration, while unbalanced forces cause acceleration, requiring a net (resultant) force.
- The relationship between force, mass, and acceleration is quantitatively defined as F = ma.
- Newton’s Third Law states that for every action, there is an equal and opposite reaction.
- Seat belts, airbags, and crumple zones aid car safety by reducing the impact force during collisions, in accordance with Newton’s Laws.
- Kinetic energy (KE) is defined as KE = 1/2 mv^2, and gravitational potential energy (GPE) is defined as GPE = mgh.
- The law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed.
- Energy transfers occur between kinetic energy and gravitational potential energy in various situations, and calculations can demonstrate this transfer.
- The human reproductive system involves the transmission of inheritable characteristics through genes during reproduction.
- Mitosis and meiosis play roles in cell production for growth, replacement, and reproduction, leading to variation within offspring.
- DNA structure controls cellular activity, and biotechnology applications include genetically modified organisms, cloning, and DNA fingerprinting.
- Mendel's experimental work contributed to the study of genetics, including the concepts of dominant/recessive alleles, Punnett squares, and genetic diseases.
