Well Levers are a simple machine that was created by someone special. Levers help us make work easier. GO LEVERS!!!! Well Levers are a simple machine that was created by someone special. Levers help us make work easier. GO LEVERS!!!!I always found it interesting that there are three classes of levers:1st class: The exerted force (Fe) is on the opposite side of the fulcrum (F)of the resulting force (Fr). For example, a pry bar.Fe-----F-----Fr2nd class: For example, a wheelbarrow:F-----Fr-----Fe(the fulcrum is the wheel)3rd class: For example a baseball batFr-----Fe-----F(the fulcrum is your hand)A fingernail clipper is a compound lever. It has a 2nd class and a 3rd class.A see-saw provides good fun. Although you might not think so your knives, forks and spoons are levers. You have the brake and gear change levers on a cycle. You might not be aware that there are three basic types of levers. Many switches are levers. Your own body has quite a few "bone" levers. When you flick a small ball of paper by using your ruler you are using a lever. You use a lever called a spoon to stir with. A bedroom door is a lever, as are most hinged things.Increasing force by mechanical advantage.>Mechanical advantage = distance moved by input / distance moved by output>Output force = input force * mechanical advantage>Force * distance = work done>(Input) force * distance = (Output) force * distance
a tennis ball will bounce the highest as in sports or a bouncy ball bounces higher than that
a first-class lever can be found in the ball of you foot.
Seesaw - The seesaw works by putting the fulcrum in the middle, and the two people on each end work as the force and the effort. This would be called a first class lever. Wheelbarrow: When the handles are lifted, the wheelbarrow is the fulcrum. This would be second class lever. Crow Bar:The crow bar is a first class lever, It's helps moves things around, like if you had a big rock to move out the way, you can use a crow bar, and you will need a smaller rock to be the fulcrum. Sport: Most sports use equipments like tennis racquets, softball bats, and cricket bats to make objects move faster and to hit objects like a ball further away. This is a third class lever
Since you need to exert force on the ball to push it away from you, the ball will obviously push back (with a force that has the same magnitude, but is in the opposite direction). This is an example of Newton's Third Law.
A hockey stick is a 3rd order lever. Elbow, Shoulder, hip, knee. All sport equipment that gives a mechanical advantage from bats & bows through to sports vehicle suspension are either levers in their own right or use levers.
Hockey sticks can be classified as such because the force is between the fulcrum (wrist/elbow/shoulder) and the load (weight of the stick/ball).
YES !
third class lever. Load/Resistance is the ball fulcrum = hip & knee
