Question

high heel vs. sneaker. same person stands on a high heel, then a sneaker. which creates greater pressure on the floor? a) sneaker b) high heel c) both equal d) depends on floor material hint: (smaller area → higher p with same force)

Explanation:

Step1: Recall pressure formula

The pressure formula is $P=\frac{F}{A}$, where $P$ is pressure, $F$ is force and $A$ is the area of contact.

Step2: Analyze force and area

The force exerted on the floor is the weight of the person, which is the same whether they are wearing high - heels or sneakers. But the area of contact of a high - heel is much smaller than that of a sneaker.

Step3: Determine pressure

Since $P=\frac{F}{A}$ and $F$ is constant, when $A$ (area of high - heel) is smaller, the pressure $P$ is larger. So high - heels create greater pressure on the floor.

Answer:

B. High heel
