This quiz tests peoples' knowledge of Inclined Planes and Levers.

• 1.

### What is an Inclined Plane?

• A.

An inclined plane is a flat surface that lies at an angle relative to level ground used to form a lever to raise and lower a load.

• B.

An inclined plane is a flat surface that lies at an angle relative to level ground used to form a ramp to raise and lower a load.

• C.

An inclined plane is a flat surface that lies at an angle relative to level ground used to form a lever to raise and lower a load.

• D.

An inclined plane is a wooden beam that lies at an angle relative to level ground used to form a lever to raise and lower a load.

B. An inclined plane is a flat surface that lies at an angle relative to level ground used to form a ramp to raise and lower a load.
Explanation
The correct answer is "An inclined plane is a flat surface that lies at an angle relative to level ground used to form a ramp to raise and lower a load." This is because an inclined plane is a simple machine that allows for the movement of objects up or down a slope with less force. It is commonly used as a ramp to make it easier to move heavy objects, such as when loading or unloading a truck. The use of the word "ramp" accurately describes the purpose and function of an inclined plane.

### ME=Wi/Wo * 100%

• A.

True

• B.

False

B. False
Explanation
The given equation ME=Wi/Wo * 100% is incorrect. There is no such equation in mathematics or any other field. Therefore, the correct answer is false.

### What does friction create?

• A.

Thermal Energy

• B.

Dust Bunnies

• C.

Sparks

• D.

Elastic Energy

A. Thermal Energy
Explanation
Friction creates thermal energy. When two objects rub against each other, the friction between them generates heat. This heat energy is transferred to the surrounding environment, increasing its temperature. Friction can be found in various everyday activities, such as rubbing your hands together or dragging an object on the ground. The production of thermal energy through friction is a result of the conversion of mechanical energy into heat energy.

### What is a lever?

• A.

A lever is a beam attached to ground by a fulcrum or hinge

• B.

A lever is a rigid beam attached to ground by a fulcrum

• C.

A lever is a beam attached to ground by a sail

A. A lever is a beam attached to ground by a fulcrum or hinge
B. A lever is a rigid beam attached to ground by a fulcrum
Explanation
A lever is a simple machine that consists of a rigid beam attached to a fixed point called a fulcrum or hinge. This allows the lever to rotate or pivot around the fulcrum, enabling it to exert a mechanical advantage and amplify the force applied to one end of the lever. The correct answer accurately describes the essential components of a lever, emphasizing the importance of the fulcrum and the rigid nature of the beam.

### What are Inclined Plane's 2 close relatives?

• A.

Wheel and axle & ramp

• B.

Screw & wheel and axle

• C.

Ramp & rope

• D.

Ramp & screw

D. Ramp & screw
Explanation
The inclined plane is closely related to the ramp because they both involve a sloping surface that allows objects to be moved up or down with less force. The screw is also closely related to the inclined plane because it is essentially a spiral-shaped inclined plane wrapped around a cylinder. Both the ramp and the screw are examples of how the inclined plane can be used in different forms to make work easier.
