Calculating Work Done When Climbing Stairs

When climbing stairs, work done can be calculated using the formula:

Work = Force × Distance

Where: - Force is the force exerted against gravity, which can be calculated as the product of mass and acceleration due to gravity (F = m × g). - Distance is the vertical height climbed.

Calculation Steps

1. Calculate Force: - The force exerted against gravity can be calculated as the product of mass and acceleration due to gravity. - The standard acceleration due to gravity is approximately 9.81 m/s^2.

2. Determine Distance: - Measure the vertical height climbed in meters.

3. Calculate Work: - Multiply the force by the distance to obtain the work done.

Example Calculation

Let's assume a person with a mass of 70 kg climbs a set of stairs with a vertical height of 5 meters.

1. Calculate Force: - Force = mass × acceleration due to gravity - Force = 70 kg × 9.81 m/s^2 - Force ≈ 686.7 N

2. Determine Distance: - Vertical height climbed = 5 meters

3. Calculate Work: - Work = Force × Distance - Work = 686.7 N × 5 m - Work ≈ 3433.5 joules

Therefore, the work done when climbing the stairs would be approximately 3433.5 joules.
