Study Notes

Energy and Motion

A moving object has kinetic energy, which is the energy of motion.
The Law of Conservation of Energy states that energy cannot be created or destroyed, only converted from one form to another.

Power and Density

Power is the rate at which energy is transferred or converted.
The equation for calculating density is: density = mass / volume.

Gas Properties

Diffusion is the process of particles moving from an area of higher concentration to an area of lower concentration.
Gas pressure is caused by the collisions of gas particles with the walls of their container.

Changes in State

When a substance is heated up, its particles gain kinetic energy and move faster.

Reproductive Biology

A gamete is a reproductive cell, either a sperm or an egg.
The male sex cell is called a sperm.
The female sex cell is called an ovum or egg.
Two adaptations of the male sex cell are: a flagellum for movement and a small head to contain genetic material.
Sperm cells are made in the testes.
Egg cells are made in the ovaries.
The menstrual cycle is controlled by hormones produced by the pituitary gland and the ovaries.
Ovulation is the release of an egg cell from the ovaries.
Fertilisation is the fusion of a sperm cell with an egg cell to form a zygote.
