A cyclist has a mass of 64 kg - Edexcel - GCSE Physics - Question 4 - 2021 - Paper 1

To calculate the gain in gravitational potential energy (ΔGPE), we will use the formula:

$$ΔGPE = m × g × Δh$$

Where:

• m = mass of the cyclist = 64 kg
• g = acceleration due to gravity = 10 N/kg
• Δh = height gained = 24 m

Now, substituting the values into the equation:

$$ΔGPE = 64 ext{ kg} × 10 ext{ N/kg} × 24 ext{ m} = 15,360 ext{ J}$$

Therefore, the gain in gravitational potential energy is 15,360 J.
