Levers and mechanical advantage

Give a real-life example of a first class lever.

• A pair of scissors

• A wheelbarrow

• A seesaw

• A door handle

What is the difference between effort and load in a lever?

• Effort is the weight being moved, while load is the force applied.

• Effort is the force applied, while load is the weight being moved.

• Effort and load are the same thing in a lever.

• Effort is the distance from the fulcrum, while load is the angle of the lever.

What are the three parts of a lever?

• Fulcrum, Effort, Load

• Pivot, Force, Weight

• Base, Pressure, Resistance

• Anchor, Power, Mass

What is the purpose of a fulcrum in a lever?

• It is the pivot point around which the lever rotates.

• It is the force applied to lift the load.

• It is the load that is being lifted by the lever.

• It is the distance from the fulcrum to the load.

What is an example of a second class lever?

• A wheelbarrow.

• A pair of scissors.

• A seesaw.

• A fishing rod.

What is an inclined plane?

• A flat surface tilted at an angle to help lift objects.

• A type of pulley used to lift heavy loads.

• A curved surface that allows objects to roll down easily.

• A vertical surface used for climbing purposes.

What is the definition of a lever?

• A type of pulley used in construction.

• A simple machine that helps lift or move loads.

• A device that measures weight.

• A tool used for cutting materials.

What is the formula for mechanical advantage in levers?

• Mechanical Advantage = Load / Effort

• Mechanical Advantage = Effort / Load

• Mechanical Advantage = Load + Effort

• Mechanical Advantage = Load - Effort

What simple machine is used to cut or split things?

• A lever

• A pulley

• A wedge

• A screw

What is the role of effort in a lever?

• Effort is the force applied to move the load.

• Effort is the weight of the lever itself.

• Effort is the distance from the fulcrum to the load.

• Effort is the amount of time taken to lift the load.
