The kinetic energy will become zero and potential energy will be decreased.

See the step by step solution

## Step 1: Potential Energy

• Energy stored in any object by means of its position is known as Potential energy
• Potential energy doesn’t gets affected by object outside or surrounding objects.

## Step 2: Kinetic Energy

• Energy of a system with respect to the motion of the particles is known as kinetic energy.
• In contrast to potential energy. the kinetic energy of a system is in correspondence to other fixed objects occurring in its surroundings

## Step 3: Example:

• So if we run down the stairs and stop at a certain time, the kinetic energy comes to 0 because the kinetic energy is dependent on the mass and speed of the system.
• The kinetic energy is formulated as; $$k = \frac{1}{2}m{v^2}$$ Where $$m$$ is the mass and $$v$$ is the Speed or Velocity of the object.
• And the potential energy is dependent on the mass of the system and the position of the system. The potential energy is formulated as; $${U_g} = mgh$$ Where $$m$$ is the mass, $$g$$ is the acceleration due to gravity and $$h$$ is the height.
• So, when a person runs down the stairs and stops, the kinetic energy becomes $$0$$ since velocity is zero. Also, as the height decreases, potential energy also decreases. ### Want to see more solutions like these?
