Forces
Definition: push or pull
What forces can do: start/stop a moving object, change the size or shape of an object, increase/decrease the speed of a moving object, change direction or a moving object
Types of forces
Objects in contact
friction/frictional force
Happens when: two objects rub against each other
Keywords: opposes movement, produces heat
Some stuff: more texture=more friction=more heat
Results of friction: Reduces slipping, allows up to control movement, produces heat, causes wear and tear, make things overheat, more things move slower
Ways to reduce friction: Use lubricants, use wheels(anything that's round), have streamlined body shapes(...)
Elastic spring force
Keywords: Stretched, compressed, change shape
Some stuff: more force=more elastic spring force=more stretched/compressed
Objects at a distance
Magnetic force
Gravity/gratitational force
Keywords: force of attraction between things that have mass
Man's impact
Negative impacts
Depletion of natural resources
Resources: Fossil fuels, metals and minerals, fish, trees
Keywords: endangered, extinct
Deforestation
Reasons: provide land for farmers, allow people to dig up fuels from the ground, for wood
Negative impacts: Organisms lose their homes, species go extinct, less rain, soil erosion
Pollution
Keywords: pollutants
Pollution can be caused by: litter, chemicals, CFCs, untreated human waste, smoke, haze, acid rain
Types of pollution: water pollution, land pollution, air pollution, sound pollution, light pollution
Global warming
Keywords: greenhouse effect, burning of fossil fuels
Caused by: burning of fossil fuels, deforestation
Positive impacts
Basically nothing, but for the sake of PSLE, I'm not gonna write "NONE" here
Conversation of natural resources
3Rs
Reducing
Reusing
Recycling
Food chains and food webs
Keywords: producers, consumers, herbivores, carnivores, omnivores, prey, predators, food relationship, upsets balance,
