A box of mass 3 kg is lifted 1.5 m onto a shelf. calculate the change in its gravitational potential energy. the gravitational field strength is 10 n/kg.

Answer: The change in gravitational potential energy is given by the formula:

  • ΔPE = m * g * Δh

where:

  • ΔPE is the change in gravitational potential energy in joules (J)
  • m is the mass of the object in kilograms (kg)
  • g is the gravitational field strength in newtons per kilogram (N/kg)
  • Δh is the change in height in meters (m)

ΔPE = m * g * Δh
ΔPE = 3 kg * 10 N/kg * 1.5 m
ΔPE = 45 J

Therefore, the change in gravitational potential energy is 45 joules.
