How does circular motion relate to Newtons laws?
Circular motion can be understood using Newton's laws of motion. The first law states that an object will remain in its state of motion unless acted upon by a net external force, which in the case of circular motion is the centripetal force that continuously changes the direction of the object. The second law describes how the centripetal force required for circular motion is related to the mass of the object, its velocity, and the radius of the circular path..TableName:Centripetal force formula.
Circular motion occurs only near the earths surface?
False. A contra example; Triton has a circular motion about Neptune Newton's first law of motion: a body remains a rest or in uniform motion in a straight line unless acted upon by a force. If there is a centripetal force towards a point acting on a body that is moving then that body will have circular motion. The body and point do not have to be on earth.
Why A stone tied at the end of a string is whirled in a circle If the string breaks the stone flies away in tangential direction?
When the stone is whirled in a circle, it experiences centripetal force, which keeps it moving in a circular path. If the string breaks, the centripetal force is lost, causing the stone to move in a straight line tangent to the circle at the point where the string broke. This concept is described by Newton's first law of motion, which states that an object in motion will continue in motion in a straight line unless acted upon by an external force.
What would be the result of an alpha particle coming into a magnetic field?
An alpha particle would move in a circular path due to its positive charge being acted upon by the magnetic field, as per the right-hand rule for moving charges in a magnetic field. This circular motion is known as cyclotron motion.
How can you use newtons first law to explain why centrifugal force does not exist?
Newton's first law states that an object in motion will remain in motion unless acted upon by an external force. In the case of an object moving in a circular path, centripetal force is required to keep the object moving in that path, not centrifugal force. Centrifugal force is a perceived force that arises from the object's inertia, rather than a true force acting on the object itself.
What will happen if you whirl a rock at the end of a string and it follows a circular path and the string breaks?
If you whirl a rock at the end of a string and it follows a circular path, the rock is experiencing centripetal force directed towards the center of the circle. If the string breaks, the rock will no longer have this inward force acting on it and will continue to move in a straight line tangent to its circular path at the point where the string broke, due to inertia. This is described by Newton's first law of motion, which states that an object in motion will remain in motion in a straight line unless acted upon by an external force.
Which law of motion states an object moving in a straight line will continue moving in a straight line at the same speed unless acted on by an outside?

Which term describes an object moving in two dimensions as it is acted on by gravity?
Projectile motion describes an object moving in two dimensions as it is acted on by gravity. This type of motion involves both horizontal and vertical components, with the object following a curved path.
When an object is moving it stays moving unless acted upon by?
When an object is moving it stays moving unless acted upon by opposing force(s). i.e. gravity, friction, etc. See Newton's 1st law of motion: related links.
A ball is whirled on a string then the string breaks what causes the ball to move off in a straight line?
Once the string breaks, the ball follows Newton's first law of motion which states that an object in motion remains in motion with a constant velocity unless acted upon by an external force. Without the centripetal force from the string pulling the ball in a circular path, the ball continues in a straight line due to its inertia.
How does Newton's first law explain circular motion?
A Partial ExplanationFirst, consider the object moving in a straight line with no forces acting upon it. According to Newton's First law, that object will always move in the same direction, at the same speed, forever. This is inertia.Now, for that object to move in a circular path, a force must act upon the object. If the force is in opposite direction of the object, the object will eventually slow down, stop, and begin reversing. The degree of slowing depends on duration and amount of force. Similarly, forces in the same direction of the object would increase velocity.Since the question asks about "uniform" circular motion, we'll assume uniform in both speed and geometry; and a uniform speed shows that no force is acting in the same direction, or the opposite direction of the object.So far, we know that there an object moving uniformly, and thus there's a force being acted upon it. Yet, we also know that force is neither "forwards or backwards." One more thing is the question asks for circular motion, not globular, so that makes this a two dimensional problem.So if there are only two dimensions to choose from, and we've eliminated the one the object is moving on, then there can only be a force acting perpendicular to the path of the object. If that path is circular, then that force will always be towards the center of the circle.Basically, think of the circle not as a long continuous path with constant force (even though it is) but as a whole series of little straight paths with a force knocking it to the side all the time, toward the center of rotation.
What is the difference of centripetal force and centrifugal force?
Centripetal force is directed toward the center of rotation of an orbiting body or object following a curved path. Centrifugal force is the apparent force, equal and opposite to the centripetal force, drawing a rotating body away from the center of rotation, caused by the inertia of the body. Whenever you see a moving object that's not traveling in a straight line, you know that a force is acting upon it. That's because objects tend to resist changes to their velocities. The greater the mass, the greater the resistance to changes in velocity. That's called inertia. Objects at rest tend to stay at rest, and objects in motion tend to stay in motion, unless acted upon by some external force. (See Newton's First Law.) Since velocity is a vector -- remember vectors have magnitude AND direction -- any change in an object's direction constitutes a changes in its velocity. When an object is flying around in a circle, its velocity is constantly changing because its direction is constantly changing! That means a force is working on it. That force is the centripetal force, and since force is equal to mass times acceleration, there must be an acceleration involved. You guessed it -- centripetal acceleration. In short: Centrifugal force is away from the center and centripetal force is towards the center. In even shorter: Centripetal force is real. Centrifugal force doesn't exist.
