How can potential energy be converted into kinetic energy?*1 pointA) When an object remains stationaryB) When an object is magnetisedC) When an object starts movingD) When an object stops moving

The conversion of potential energy into kinetic energy occurs when an object starts moving. So, the correct answer is C) When an object starts moving.

Here's a step-by-step explanation:

1. Potential energy is the stored energy in an object or system because of its position or configuration. This could be due to its height (gravitational potential energy), its condition of being stretched or compressed (elastic potential energy), or other factors.

2. When the object's position or configuration changes in a way that reduces its potential energy, this energy doesn't just disappear. Instead, it gets converted into another form of energy.

3. If the change involves the object starting to move, the potential energy is converted into kinetic energy, which is the energy of motion.

4. For example, consider a ball held at a height. While held, it has gravitational potential energy. When it's released, it starts falling, i.e., it starts moving. As it falls, its height and therefore its gravitational potential energy decrease. But now it's moving, so it has kinetic energy. The potential energy it lost has been converted into kinetic energy.

5. Therefore, potential energy can be converted into kinetic energy when an object starts moving.

The conversion of potential energy into kinetic energy occurs when an object starts moving. So, the correct answer is C) When an object starts moving.

Here's a step-by-step explanation:

1. Potential energy is the stored energy an object has because of its position or state. For example, a book on a shelf has potential energy because of its position high above the ground.

2. When the book falls off the shelf, the potential energy is converted into kinetic energy. Kinetic energy is the energy of motion.

3. As the book falls, it speeds up, which means its kinetic energy increases. At the same time, its potential energy decreases because it's getting closer to the ground.

4. By the time the book hits the ground, all of its potential energy has been converted into kinetic energy.

So, potential energy turns into kinetic energy when an object starts moving.
