What is natural forces?
Natural forces are a invisible force trying to keep the world balanced. Pull and push are both natural forces so is gravity.
When forces are not balanced an object may keep object moving forever true or false?
That's true. Plus ... even if the forces on an object are BALANCED, it can keep moving forever.
When forces are not balanced an object keep moving forever?
As long as the forces remain the same or do not change direction
Why are balanced forces important in a tennis game?
Because your legs keep moving
What are the condition for an object to keep moving at constant velocity?
No resultant forces act upon it
Why don't things keep moving forever?
Things would were it not for opposing forces such as friction.
How do planets in the solar system keep moving?
An object has a general tendency to keep moving - that's how our Universe works. No force is required to keep an object moving - unless there is another force that slows it down. Here on Earth, there are usually frictional forces that slow objects down, and therefore a force is required to counteract the frictional forces.
What is a heavy piece of metal for lowering into the water to keep a ship from moving?
An anchor is a heavy piece of metal for lowering into the water to keep a ship from moving.
Are there any forces acting on you in the direction you are moving?
Maybe, maybe not. Forces don't happen because you're moving ... forces are what cause you to move. If there are no forces acting on you, then you keep moving whichever way you're moving, and your speed or direction don't change. If there are forces acting on you, then your speed and/or direction can change. If the force is in the same direction that you're already moving, you'll move faster (accelerate). If the force is in the direction opposite to the direction you're moving, then your speed will decrease. Does any of this sound surprising ???
When are forces necessry to keep things moving?
Whenever another force - usually friction - slows it down.
Why does it make more energy to stop a moving ball than the energy required to keep it moving?
The natural tendency of a moving object is to keep moving. And it doesn't really require energy to stop it; in fact, in theory, you can gain energy from it. What is required is a force.
Why does an object in space keep moving at the same speed?
That's the way our Universe works; that's the natural tendency of any object - to keep moving at the same velocity (same speed and in the same direction). However, in our everyday experience this isn't so obvious, because there are normally forces of friction at work, that slow objects down.
