2. What does friction create?

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.

3. What is an Inclined Plane?

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.

4. ME=Wi/Wo * 100%

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.

5. What are Inclined Plane's 2 close relatives?

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.

7. A lever is used to lift a 200 kg load. The effort force applied is 50 N, and the distance from the effort to the fulcrum is 2 meters. If the load is 0.5 meters from the fulcrum, what is the mechanical advantage (MA) of the lever?

Explanation

The mechanical advantage (MA) of a lever is calculated by dividing the effort arm length by the load arm length. Here, MA = 2 meters / 0.5 meters = 4. This means the lever multiplies the applied force by 4, making it easier to lift the load. Understanding MA is crucial in determining how levers and inclined planes reduce the effort needed to perform work.
