Question 1

A ball is thrown horizontally from a cliff. Ignoring air resistance, what happens to its horizontal speed as it falls?

Accepted Answer

It remains constant.

Answer

Gravity acts only vertically; without air resistance, horizontal velocity remains constant throughout the fall.

Question 2

Which shape has the most structural strength when used as a construction element?

Accepted Answer

Triangle

Answer

Triangles distribute load evenly and cannot deform without changing side lengths, making them the strongest structural shape.

Question 3

Two pulleys are connected by a belt. Pulley A has a diameter of 10 cm and rotates at 100 RPM. Pulley B has a diameter of 5 cm. How fast does Pulley B rotate?

Accepted Answer

200 RPM

Answer

Belt speed is constant; RPM ratio is inversely proportional to diameter: 100 × (10/5) = 200 RPM.

Question 4

A cube is painted red on all sides and then cut into 27 equal smaller cubes. How many small cubes have exactly 2 red faces?

Accepted Answer

12

Answer

Edge cubes (not corner, not face center) have exactly 2 painted faces; a 3×3×3 cube has 12 edge positions.

Question 5

A ramp reduces the force needed to lift an object. If a 300-lb object is lifted using a 6-foot ramp to raise it 2 feet, what is the mechanical advantage?

Accepted Answer

3

Answer

Mechanical advantage of a ramp = ramp length ÷ height = 6 ÷ 2 = 3.
