An example of zero acceleration would be what?
If you are moving at a speed of ceratin speed and there is no force trying to slow you down, and there is no force trying to speed you up. Then there is zero acceleration. An example would be : an object in out in space, if you throw a object away from you the object will float away, since there is no force working on the object after you throw it the object is moving away in a locked speed from you, but have zero acceleration because there is no force affecting the object
What happens when force is applied to an object?
When a force is applied to an object, it accelerates. for example, if you push an object, the object accelerates away from you and, eventually, will move away from you..
How is momentum determined?
momentum is determined by the force that the object is pulled or pushed by or it can be determined by the position it's in. ex: when a cart is pushed down a hill when you're on roller skates and you're on the part of the hill that is like 5" away from top
Does buoyant force depend on the density of the object?
No, it depends on volume of water displaced, density has nothing to do with it. Think of it like this: if that object wasn't there, wherever it is would be filled with water. Thus, the force on it depends on how much water it pushed out of the way. As much water as it pushed away is how much force the water, as a whole, is exerting on it. the reason denser objects displace more water is this: they are heavier. the Force of gravity is constant, and so the greater mass (density is mass/volume) the greater the downward pull. Thus, the object can push more water out of its way, because it has greater force to push with. Therefore, to reach equilibrium, where the forces cancel, the object must sink to the point that buoyant forces and gravity are equal, and since gravity is greater, it must sink to a greater buoyant force.
What kind of force moves an object away (4th grade)?
The two major forces that act upon a body are centrifugal force and centripetal force. Centrifugal force causes a body to fly outwards, or moves a body away and centripetal force counteracts centrifugal force, preventing the object from flying out and keeping it moving with a constant speed, in a circular path.Search templates (CTRL+Space) New TemplateHide button
What kind of force moves an object away?
By definition, any force enacts a change in momentum. Momentum is mass times velocity, so a force is a change in mass and/or velocity. Since mass is usually constant, any force therefore enacts a change in velocity, and thus moves an object away.

What force pull an object away from the center of a curved path?
Inertia is the "force" that causes an object in a curved path to pull away from the center. Inertia is actually the tendency of anything with mass to resist a change in motion. In other words, an object at rest will not move because of inertia, unless it is acted on by an unbalanced force, and an object in motion will continue to travel at a constant speed in a straight line unless acted on by an unbalanced force. An object traveling in a circular path pulls away from the center because inertia tries to keep the object traveling in a straight line.

Why object in space float away and in which direction?
An object in space won't float off in any direction unless it is pushed. When it is it will go in the direction it is pushed and continue until it is either pushed again or bumps into something.
How just rocket goes upward?
Upon expulsion of various gases it is propelled upwards by the force of gravity. Under the laws of gravity, objects that push an object away (the rocket expelling gases) will be pushed on by that object (the gas pushes the rocket up).
What force pulls an object away from the center?
gravity...
Is the force of an object doubled if the velocity of an object traveling in circluar motion is doubled holding the radius constant?
If we're going to have this discussion, we need to change the playing field a bit.There's no such thing as the "force of an object". The only force that it makessense to talk about in this situation is the force on the object. That's the forcethat makes the object travel in a circular path, and it's called the "centripetal" force.In order to make an object move in a circular path, a constant force has to act on it,always directed toward the center of the circle. The force could be the tension ina yo-yo string, the friction between the race car and the track, or the gravitationalattraction between a body in a circular orbit and a big mass at the center.If the radius of the path remains constant but you want the object to revolve around ittwice as fast, then it needs 22 = 4 times as much centripetal force to keep it on thecircle, otherwise it skids away to a larger radius.
