Based on the data provided, the thermal energies at the given time intervals are as follows:

  • At time t = 0.0 secs; thermal energy = 0.0 J
  • At time, t = 0.8 secs; thermal energy = 0.0 J
  • At time, t = 2.0 secs; thermal energy = 3.9 J
  • At time, t = 2.8 secs; thermal energy = 6.7 J

What is the law of conservation of energy?

The law of conservation of energy states that the total energy in an isolated system is conserved.

For a ball undergoing energy conversion between kinetic and potential energy, the sum of the energy remains constant.

Any reduction in total energy is due to conversion of some energy to thermal energy.

  • Sum of energy: Kinetic + potential + thermal = 15.2 J
  • Thermal energy = 15.2 - (PE + KE)

At time t = 0.0 secs

Thermal energy = 15.2 - (15.2 + 0.0)

Thermal energy = 0.0 J

At time, t = 0.8 secs

Thermal energy = 15.2 - (4.7 + 10.5)

Thermal energy = 0.0 J

At time, t = 2.0 secs

Thermal energy = 15.2 - (7.4 + 3.9)

Thermal energy = 3.9 J

At time, t = 2.8 secs

Thermal energy = 15.2 - (8.5 + 0.0)

Thermal energy = 6.7 J

Therefore, the thermal energies at the given time intervals are as follows:

  • At time t = 0.0 secs; thermal energy = 0.0 J
  • At time, t = 0.8 secs; thermal energy = 0.0 J
  • At time, t = 2.0 secs; thermal energy = 3.9 J
  • At time, t = 2.8 secs; thermal energy = 6.7 J
