Questão	Responda
How do Ramps make climbing easier?	They reduce the effort force needed. Image: 7b5dde8e-2faf-44d3-85f5-2af965dad7c8 (image/jpeg)
How do ramps do this?	They made you travel over a longer distance. Image: 76ebfb02-f59e-4bd1-a6da-2ea046504971 (image/jpeg)
In order to use less force effort climbing a mountian, what do you have to do?	You have to travel a greater distance to make it easier. Image: e709da32-f7b4-4ed0-9e1e-a00361778b8e (image/jpeg)
What is a ramp?	An inclined plane used to help lift an object. Image: b605580b-c3a1-4f80-b084-ae6e477f4e75 (image/jpeg)
What is an inclined plane?	A simple machine that reduces the effort needed to lift a load by increasing the distance it acts Image: 309c695f-07b6-498e-95c8-92c240be7be0 (image/png)
What are wedges?	They are double inclined planes. Image: ade8d4a3-97ab-4160-be26-8cedc5db558d (image/png)
What do wedges do?	,They are used to split objects because they change the directions of the force by 90 degrees and increase its size. Image: 0a20504e-0310-4a2a-bf53-1b070e7409dc (image/jpeg)
What happens when an axe is pushed downwards on a piece of wood?	The wedge of the axe head pushes the wood apart. Image: 2b0edf5d-790d-44a6-befc-c7a474abfe65.gif (image/gif)
What are some examples of wedges?	Pins, needles, nails, doorsteps, your incisors. Image: b101e9e0-92ae-40b2-b6c5-d6398ead6420 (image/jpeg)
Does a wedge change the direction of a force or speed it up?	It changes the direction of a force. Image: d4904c85-c643-4e8c-b00a-2b17c5c34600 (image/jpeg)
What happens when the inclined edge of the wedge is longer and the axe is sharp?	They longer the wedge and the sharper the axe, the easier it is to cut the wood. Image: 7bbefff3-7f14-48e6-a159-54a0b2c47816 (image/jpeg)
Why are ramps use in buildings?	They are used to make it easier to deliver goods to shops and easier for people with wheelchairs or prams to enter the shop. Image: 4e073314-9ac1-45a9-bbf2-acc2d0a99a28 (image/jpeg)
How do you find the mechanical advantage of a ramp?	Image: 0dc3a25a-8392-4b13-9993-303ea78a85de (image/png)
Give some examples where zips can be found.	Clothing, purses, wallets, sleeping bags, suitcases, handbags, backpacks and pencil cases. Image: ecf2e174-3164-40e7-baf2-3ac5e93350e1 (image/jpeg)
What does a zip consist of?	Two sets of interlocking teeth that are very strong when fastened. Image: 92847fb9-ce09-4974-bd72-924015d7dba8 (image/jpeg)
How many wedges does the slide of the zipper use to zip up and unlatch something?	It uses three wedges. One of each side of the teeth and one in the middle used for opening the teeth. Image: 2c086682-a948-4886-ac80-ae57c876b71b (image/jpeg)
What is a screw?	It is a spiral-shaped inclined plane. Image: e46ee513-84ce-467a-8501-1c7204c74892 (image/jpeg)
What is it designed to do?	It is designed to cut through another substance. Image: 2eef5e64-68c5-471a-a6fb-3b30e0b42eff (image/jpeg)
How is using a screwdriver using less force than hammering it into the piece of wood	It is because as you are turning the screwdriver, you are moving the screw over a larger distance that makes it much more easier than if it were hammered directly into the wood.

What is the thread?	It is the spiral inclined plane around a metal screw. Image: 66a29445-6f64-4452-8613-07c97b826d0f (image/png)
What is the pitch?	The distance between adjacent threads on a screw. Image: 801dca42-e46c-426e-a88f-cd6315246d6e (image/png)
Would is be easier to use a screw with a small pitch or a large pitch?	The smaller pitch because you need to turn it over many times by the screwdriver with less force. The one with the larger pitch requires less turns but more effort. Image: da43cb43-de5f-4610-9fdf-b47104f0fcd8 (image/png)
Hope you learned something :-)	Image: a52a09d3-4aa1-47ca-9f27-de834716d5d5 (image/jpeg)
