I saw a pulley and the forces where mostly gravity and friction

when i saw the video i thought that its only gravity but there is friction gravity and air resistance
I really liked the video 4TF it was very funny and very interesting. I know there was the force gravity. There was also a song from the grade 2 it was also funny. it was fun when he let go of the rope because only for a butterfly!!!!!! What was he thinking about ?!!
I think this move is about forces because in the move its say gravity so mach and the move is so fun and its allsaw says streching. rast part is fun.
He did not let go of the rope. The barrel went down.
where are the simple machines and the forces
The bricks are more havey then the human and gravity pulls the hevey bricks then the human comes up and hits the top then the bricks hit the bottom so it loses wight and in comes up the person falls on the bricks then lets go and it falls down and he gets hearts
There are lots of disasters in the video because there are lots of forces acting at the same time and i feel really bad because he brakes so many bones and there is allot of friction because the barrel and the man met allot
One force is called gravity,air resistance,friction.
In the brick layer's DISASTER! The forces I saw were; - GRAVITY when he went down and when the bricks went down- FRICTION between the rope and the pulley and him and the barrel- AIR RESISTANCE when the butterfly was flying because otherwise it would be a stick-insect with wingstf13
In the Bricklayer's disaster, like gravity was acting on the Bricklayer and the barrel when they were lighter than each other. There was also friction when they hit and rubbed against each other.The other force I saw was when the Bricklayer was pulling the rope and he was lighter than the barrel so he flew up.The simple machines I saw were: a pulley were the rope was hanging, his body, a barrel and a rope.
There was gravity forcing the bricks down there were pulleys making it easy'er to pull the bricks up
there was gravity with the pulley or barrel the man was pulling the the barrel and when he hit the barrel there was some friction with the man touching the barrel and also some friction when he hit the pulley, that made him make friction and hen gravity pulled him down because when the barrel hit the ground it made him the heavist of them all so then he started falling because gravity got more force on him and the butter fly had air risistence because unlike a rock, a rock does not have air risistence because the air does not really push it there was gravity and friction when he hit the ground.
In the video 'The Bricklayer's Disaster', the forces there were is:- There was gravity when the barrel of bricks fell.- There was friction when the bricklayer and the barrel of bricks smashed together.- There was also friction when the pulley and the rope was rubbing against each other.- There was air-resistance when the butterfly was flapping it's wings.The simple machines in the video were:- The pulley- The bricklayer's body- The rope- The barrel
