This section covers the following syllabus (Physics 5059) requirements.
show understanding that kinetic energy, potential energy (chemical, gravitational, elastic), light energy, thermal energy, electrical energy and nuclear energy are examples of different forms of energy
state that kinetic energy Ek = ½ mv2 and gravitational potential energy Ep = mgh (for potential energy changes near the Earth’s surface)
This section covers the following syllabus (Physics 5059) requirements.
state the principle of the conservation of energy and apply the principle to new situations or to solve related problems
apply the relationships for kinetic energy and potential energy to new situations or to solve related problems
This section covers the following syllabus (Physics 5059) requirements.
recall and apply the relationship work done = force × distance moved in the direction of the force to new situations or to solve related problems
This section covers the following syllabus (Physics 5059) requirements.
recall and apply the relationship power = work done / time taken to new situations or to solve related problems
calculate the efficiency of an energy conversion using the formula efficiency = energy converted to useful output / total energy input
