Science - Forces👩🏼‍🔬⭐️

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
