Inertia
Plants can help stabilize sand dunes and prevent them from moving.
the heart never relaxes and the blood always keeps on moving to other parts of the body
Repairs, such as repainting the residential rental property, are currently deductible expenses. A repair keeps your property in good operating condition. It does not materially add to the value of your property or substantially prolong its life. Repainting your property inside or out, fixing gutters or floors, fixing leaks, plastering, and replacing broken windows are examples of repairs. If you make repairs as part of an extensive remodeling or restoration of your property, the whole job is an improvement. In that case, you should capitalize and depreciate the repair costs as the same class of property that you have restored or remodeled as discussed above. For more information, refer to Publication 527, Residential Rental Property, and Publication 946, How to Depreciate Property.
Well there is nothing that "fuels" the water cycle since we have been recycling the same water for billions of years. You could say that the sun keeps the water cycle moving however.
Inertia. The moon is constantly "falling" towards Earth, but it's also moving sideways so fast that it constantly misses and therefore remains in orbit.
It is called "inertia", but we still don't really know what it is.
It's Newton's first law of motion: "An oject in motion will stay in motion (with the same velocity) until an outside force acts upon it and an object at rest will stay at rest until an outside force acts upon it."
The force of gravity keeps the space station in orbit as well as inertia that keeps the space station moving in a straight line.
A moving object keeps moving, unless you force it to stop. It keeps moving in a straight line, unless you force it to change direction. It keeps moving at a constant speed, unless you force it to speed up or slow down. A stationary object remains stationary, unless you force it to start moving.
I think it has something to do with electron capture.
Bad form. A skilfully thrown bowling ball travels on a curve.
It's not that there is some force keeping the planets from falling into the sun; the sun's gravity prevents the planets from travelling in a straight line out of the solar system. If you throw a ball in a straight line then it keeps going, but if you throw a ball on a rope tied to a pole then the rope pulls the ball toward the pole and keeps the ball moving in a circle.
inertia keeps moving it!:)
The pumping of the heart keeps the blood moving
The rotation of the earth keeps a foucault pendulum moving
The motivation is the electromagnetic repulsion of electrons.
Sun's gravitational pull keeps the earth in an elliptical orbit around it.If there would be no gravitational pull of sun on earth than the earth would start moving in a straight line at an angle of 90 degree like a tangent to a circle.
