We saw that if two gears are placed together, they will rotate in the opposite direction to each other. If gears with two differing sizes, one big and one small, the smaller one will rotate faster than the bigger one.

The size of a gear is measured by the number of teeth it has.

If there will be a large amount of friction, the gears will not work.

Diameter is the distance from the center of the circle and is equal from every angle of the circle. Radius is half of the diameter and circumference is the measurement of the boundary of the circle.

This movie explains how gears come in different shapes and sizes. All gears have teeth, and the larger your gear is the more amount of teeth are present. Gears opposite to each other rotate the opposite ways in order for them to work together. We learned about the different parts of a gear structure .

We learned about the circles and their diameter, radius, and circumference through the form of a song. The diameter is the straight line passing through the middle of the circle. Whereas, the radius is teh lines issuing from the centre of the circle to its perimeter. Lastly, the circumference is the linear distance around the edges of a circle.They also told us about how wwe need to put force onv these kind of things.they also told us in which dirction dose it go

     Movie review  i have seen two movies in which I have learned about functions of gear as well as I have seen what friction and torque force is. Gear is a circle with claws to make thins move. They are usually used to make the car move or making other objects like robots to make them work. Torque is a force which helps in rotating. Like turning a ridge to tighten a bolt produce torque or an engine which moves up a tire of a car uses the force torque.  While friction is a force which occurs when an object stops. Like stopping a full speed car creates the force friction. The reason why volleyball stops after rolling a long distance. This is cause of friction.

In the three videos we learnt how the basics of gear changing, we learnt how force effect the movements of the gears for example when one gear is moving counter clockwise the other will be moving in the other direction. And if the two gears are different in sizes it will affect the speed as the smaller one will move faster than the bigger one.

In the second video we learnt about the different concepts and formulas used to measure circles through a song. Diameter, circumference and radius of a circle.

In the movie we learnt about Gears which are bigger in size as compared to the smaller ones. Some Gears move clockwise and some anti-clockwise.

The second movie was about how to calculate diameter, radius and circumference of a circle. It was presented through a song. W learnt the formulas.

WE REVIEWED IN THE MOVIE ABOUT DIAMETER, CIRCUMFERENCE AND RADIUS.

I LEARNT THAT WE CAN INCREASE FORCE TO OPEN SCREW AND LEARN HOW GEAR AND GEAR WHEEL WORKS CLOCK WISE AND ANTI CLOCK WISE.

DISTANCE AND FORCE IS USED TO INCREASE THE TORK.

RADIUS IS THE HALF OF THE DIAMETER.

A BIG GEAR TAKES TIME TO ROTATE COMPARE, TO THE SMALL ONE.

In the first movie we learn t about gears. Gears which are bigger in size and have more teeth as compared to the smaller ones which have less teeth. Some gears move clockwise whereas others move anti-clockwise.

In the 2nd movie we heard a song which was about the circle. We learn t about the formulas of how to calculate the diameter, radius and circumference of a circle.

In the 3rd movie we learn t about torque.

In this movie we learnt Friction is a force that stops an object and can help in changing the direction of a certain thing. The gears have teeth which are equal to circumstance, the rotation of the gears depend on the size. Radius is equal to half circle, diameter is equal to a double radius.  by anousha

Today I watched clips in that I learned about gravitational force that how the earth attracts everything to its gravity in the middle point. Friction is that how something stops. In mechanical engineering we learned that how the speed increases and decreases by the help of gear. If the gears would be both of the same size then the vehicle will move slowly whereas if they would be of different sizes like one is big and other is small then the vehicle will move rapidly fast. I also learnt about the gear system which effects the car motion.

Today I watched clips in that I learned about friction force that how the moving object is stopped by a force. I learned more about gears as the size effect the speed and ratio of an object. If the gear will be of same size so the vehicle will move slowly whereas if one will be big and one small so he vehicle will move faster. I also learned about the gear system which effect the car motion.

        Movie Review Friction is a force that stops any objects and can change its direction and movement. In this movie we learned about gears and how they work. The gears have teeth and which is equal to circumference, the rotation of the gears depends on the size. Radius is the half of diameter and diameter is double radius. We also saw two gears one was smaller and the other one was big, they have different sizes that’s why they have different amount of rotation.

Movie review

We learnt from the movie was about gears and friction. We saw a circle in which they were telling about radius, diameter and circumference, radius is the half of diameter and diameter is double radius. Circumference is the area covered by the circle. We also learned about ratio and how the gears move.

Gears is one of a set of toothed wheels that work together to alter the relation between the speed of a driving mechanism (such as the engine of a vehicle or the crank of a bicycle) and the speed of the driven parts and is designed to adjust the gears in (a machine) to give a specified speed or power output. Gravitational force is a force that attracts any objects with mass. Torque is a twisting force that tends to cause rotation. Friction is the resistance that one surface or object encounters when moving over another. Diameter is a straight line passing from side to side through the center of a body or figure, especially a circle or sphere. Radius is a straight line from the center to the circumference of a circle or sphere. Circumference is the enclosing boundary of a curved geometric figure, especially a circle.

Gears helps to move vehicle and machine .Gears Help in increase speed and slowing speed. Radius is in centre of circle. Diameter is line between circles. Gravitational force that how the earth attract everything in gravity in middle point. Friction is that how something stop.
