Initial Push

The energy, force or effort in the initial stage would be far more than what is required for the object to keep moving. If our project, like starting a new business, was like launching a rocket, we would like to start it with the initial super thrust, but we also need to keep the momentum going.

The entire journey requires some amount of energy to keep moving forward. It also moves in one direction only, and changing its direction needs a considerable amount of effort and force.
