Effort is lost in friction .
Yes, a small force applied over a long distance is an example of effort in the context of work or physics. In simple terms, effort is the force exerted over a distance to accomplish a task. This concept is often used in mechanical systems to calculate work done.
advantage of repeater is cover small distance ,so you can installation in small village that it has few subscriber. Also easy to installation and take less time.
small steps for life promots respect for the athlets
Big chainwheel(by the pedals) and small sprocket(at the rear wheel) = big effort. Small chainwheel and big sprocket = small effort
a hatch is a small opening in a door or cover.
cover slip is a small piece of glass which is used to cover.
This will occur if the fulcrum is closer to the load than the effort
a speed multiplier is an object which moves at high speed and multiplies that to create more speed with an object it is trying to move. an example is hitting a tennis ball with a tennis raquet - you swing your arm/hand at a short distance at high speed and great effort so travels a great distance at an even higher speed. the distance the ball moves is large so the force by your arm/hand is small. hope this helps! :)speed multiplier- machine that requires a small movement of an effort to produce a large movement of a load, such as a third class lever.source: Pearson Science S.B
They aren't designed to be anything other than cover from the rain. However the round shape means the frame takes allot less effort to make and bind together and It only requires 1 big skin to cover it. Quite a clever design really. Even if they can be quite small.
Small wheels on a mousetrap car can be bad because they rotate more times to cover the same distance compared to larger wheels. This increases the rolling resistance and friction, making it harder for the car to move and reducing its efficiency and speed. Additionally, small wheels may have less traction, leading to slipping and less grip on the surface.
A block and tackle consists of a system of pulleys with a rope and hook. It is a simple machine which lets you lift a heavy weight more easily. We say it gives you a mechanical advantage,or that it is a force multiplier because it lets you trade a large distance by which you pull the rope using a small effort for a small distance lifting the heavy weight. An example is an engine hoist.
TALL boys run faster than SHORT boys as a rule, because their longer legs cover a greater distance in one stride.
