If an object is in motion it will stay in motion
A green plant has Chemical energy.
This chemical energy is stored as Chlorophyll which in turn reacts with sunlight and water, to form sugar through the process of Photosynthesis.
Explanation:

Examples of a non-contact force are gravity and magnetism.
