Answer 1

Answer:

pls mark as brainiest answer pls

Explanation:

1 Everyday Examples: Law of Conservation of Energy. The law of conservation of energy can be seen in these everyday examples of energy transference: ... Water falls from the sky, converting potential energy to kinetic energy. This energy is then used to rotate the turbine of a generator to produce electricity

3 ZERO WORK:The work done is said to be zero work when force and displacement are perpendicular to each other or when either force or displacement is zero. example: When we hold an object and walk,the force acts in downward direction whereas displacement acts in forward direction
