What is magnetism?
is the force that takes place when a magnet or mag. Material pulls a melatonin item or other magnets towards itself
What are 3 magnetic materials?
Iron, nickel, and cobalt
What is Bouyancy
is the force that in a fluid pushes an item upward
What is Gravity ?
is the force that pulls us, other planets and other objects on the ground towards the sun
What is Friction
is the force that stall or stops us wenn we are trying To move an object. This happens when too matériels touch, friction is always slowing and stopping moving objects.
What is air resistance
is a type of friction which aCcurs between air and other objects
What happens when an object has bigger mass
The more mass an object has the more force it will pull gravity
What are three greenhouse gases?
Carbon dioxide, methane, and nitrouse otride
What is Stream lining
is to desing something so that there is little water- or airresistants slowing it down. Streamlining developers speed and lessons movement
What is The seconde law of motion?
Speeding up accurs when a force is applied to an object the heavier the object the more force will be need to applied to it
What is The 1 part of the first law of motion ?
Is something that is still, will remain still unless a force is applied to it.
What is The 2 part of the first law of motion ?
Something that is moving wil remain moving in the same direction and in the same speed undies a different force is applied to it
What is The third law of motion?
For every action these an equal an opposite reaction in response. (Because forces work in pairs of two)
What is an example of a situation we’re more friction would help us ?
When we rub our hands together
What is an renewable energy source?
It is a energy source that comes from natural resources, is sustainable, doesn’t harm the environment and air naturally replenished
Who’s is unsustainable energy source?
It is a energy source that come from natural resources but aren’t naturally deplenished, can only be used niece and isn’t sustainable
What is global warming ?
Is the long-term war inning of the planets overall temperature
What is The greenhouse effect?
Is the way in which heat is trapped close to earths surface by greenhouse gases. It keeps the earth warm so that our planet can support life
How to we measure forces with?
Newtons
What do we measure gravity with?
weight
