1. The relationship between work and energy is that work is the transfer of energy. In the examples, a cricket ball transfers its kinetic energy to the wicket, doing work on it, and a falling hammer converts its potential energy to kinetic energy, doing work on the nail by driving it into the wood.

  2. A raised hammer demonstrates potential energy due to its height above the nail. As it falls, this potential energy converts into kinetic energy. When the hammer strikes the nail, the kinetic energy is transferred to the nail, driving it into the wood.

  3. An object raised to a certain height has gravitational potential energy, calculated using the formula PE = mgh, where m is the mass, g is the acceleration due to gravity, and ℎ is the height above the reference point. This energy enables the object to do work when it falls.

  4. Kinetic energy is the energy possessed by an object due to its motion. In the example of the cricket ball hitting the wicket, the fast-moving ball demonstrates kinetic energy, transferring it to the stationary wicket upon impact, causing the wicket to be thrown away.

    Tidal energy is harnessed by capturing the energy from the rise and fall of sea levels caused by the gravitational forces of the moon and the sun. This energy can be converted into electricity using tidal turbines or tidal barrages. Tidal energy is most effectively utilized in areas with high tidal ranges, such as the Bay of Fundy in Canada.
