Simple Machines

What is a simple machine?

• A device that helps to reduce the amount of force required to work.

• A complex mechanism that requires multiple parts to function.

• A tool used for measuring distances accurately.

• An electronic device that automates tasks.

What is an inclined plane?

• An inclined plane is a flat surface that is horizontal.

• An inclined plane is a sloping surface, like a ramp, that reduces the amount of force needed to lift an object.

• An inclined plane is a vertical surface used for climbing.

• An inclined plane is a circular surface that rotates around a point.

What is an example of a simple machine used in construction?

• Lever

• Inclined Plane

• Pulley

• Wedge

What is a screw?

• A type of fastener that converts rotational motion into linear motion, often used to hold objects together.

• A tool used for cutting wood and metal.

• A device that measures the depth of water.

• A type of lever used to lift heavy objects.

Can you name a compound machine?

• Bicycle

• Hammer

• Screwdriver

• Wrench

What is a wheel and axle?

• A type of gear used in machinery.

• A simple machine that consists of a larger wheel attached to a smaller axle, allowing for easier movement.

• A device used for lifting heavy objects.

• A mechanism that converts rotational motion into linear motion.

How does a ramp help in lifting objects?

• A ramp allows objects to be moved upward with less force than lifting them straight up.

• A ramp increases the weight of the object being lifted.

• A ramp makes it impossible to lift heavy objects.

• A ramp is only useful for sliding objects downwards.

What is a pulley?

• A device used to lift heavy objects by changing the direction of force.

• A grooved wheel with a rope running along the groove.

• A type of lever that amplifies force.

• A simple machine that reduces friction in moving parts.

What are the simple machines that make up scissors?

• 2 pulleys and 2 levers

• 1 lever and 3 inclined planes

• 2 levers and 2 inclined planes

• 3 levers and 1 pulley

What is a wedge?

• A type of screw used for fastening objects together.

• A simple machine that is used to split or cut objects apart, consisting of two inclined planes.

• A tool used for measuring angles in geometry.

• A device that converts rotational motion into linear motion.
