What are the forces acting on a satellite that is in a circular orbit about the Earth at an altitude at which air resistance is negligible?
There's just gravity acting as the centripetal force keeping the satellite in its circular orbit. This force is equal to GMEm/r2 = ma = mv2/r.
The universal law of gravitation is a math equation that enables you to calculate which of the following?
answer is these two: 1.) The centripetal force of the Earth as it circles the sun in its orbit 2.) The gravitational force of attraction acting between any two masses
What forces are acting on objects that are moving with circular motion?
Some Forces do not involve physical contact between the bodies on which they act. -Jauan Williams 3182163642
If an object moves along a curved path at constant speed is a force is acting upon it?
Yes. The centripetal force acts on any body moving along a curved path. It acts along the radius of the path and is pointed towards the centre. If friction is in the equation there will need to be a force behind the object to counter the slowing effect as well.
What is real law of gravitation of newton in his own words?
Newton's Law of Universal Gravitation was first published in 1687 as part of his book,Philosophiæ Naturalis Principia Mathematica. The publication is free of copyright, and may be viewed online.Newton did not originate the concept of gravity, but was the first to demonstrate that the motion of the celestial bodies could be explained if they were acting under an attractive force which was inversely proportional to the squares of the distances between them, and proportional to their masses. The gravitational constant was not determined until two centuries later. Newton did not promote the invisible force of gravity in his work, or attempt to explain it. The book solves the equation of motion for several types of orbits acting under several different forms of radial forces, and explains several astronomical observations with an inverse square form.The actual statements are similar to this one, "if bodies move uniformly in concentric circular orbits whose periods vary as the 3/2 power of the radii, then the centripetal forces acting on these bodies vary as the inverse-square of the radii of the orbits."
Does the centripetal force acting on an object in uniform circular motion do work on the object?
No
What is the origin of centripetal force?
Centripetal force is the resultant force acting towards the centre of orbit of an object undergoing uniform circular motion.
What are the forces acting on a satellite that is in a circular orbit about the Earth at an altitude at which air resistance is negligible?
There's just gravity acting as the centripetal force keeping the satellite in its circular orbit. This force is equal to GMEm/r2 = ma = mv2/r.
What type of circular motion is going around on a Ferris wheel without stopping an example of?
The type of circular motion on a Ferris wheel without stopping is an example of uniform circular motion. In this type of motion, the speed of the object remains constant, but its direction changes continuously, moving in a circle at a consistent rate.
The centripetal force that makes the Moon travel in a circle around the Earth instead of continuing in a straight line is?
As the moon orbits the Earth, the force of gravity acting upon the moon provides the centripetal force required for circular motion.
What is A 0.25 kg stone tied to a 0.5 m string whirls at a speed of 4 m s What is the centripetal acceleration acting on the stone?
Centripetal acceleration = V2/R = (4)2/(0.5) = 32 meters/sec2The centripetal acceleration doesn't depend on the stone's mass.(The centripetal force does.)The centripetal acceleration doesn't "act on" the stone.(The centripetal force does.)The centripetal force acting on the stone is F = M A = (0.25) (32) = 8 newtons.
What is the centripetal force that causes it to move in a circle?
Centripetal force, which is the product of the mass and the centripetal acceleration.Fcp = m x acpYou can measure the acp in various ways:acp = v2 / r acp = ω2 x r
When you're driving in a car and turn a corner centripetal force from the door of the car helps you move along the circular path of the corner?
Centripetal force acts on all masses subjected to the cornering force. The whole vehicle has centripetal force acting on the tires, via friction, allowing the vehicle to corner. If you are free to move within the vehicle, yes, the door will stop you being flung outward.
What decreases the centripetal force?
If a body of mass m is in uniform circular motion with speed v and radius r, then the force acting on it has magnitude F = mv2 / r and is directed towards the centre of the circle. This is termed a "centripetal" (meaning "centre-seeking") force. To decrease the magnitude of the centripetal force, you must therefore either decrease the mass of the body, decrease the orbital speed, or increase the radius of the orbit.
What is the formula to find centripetal force?
Centripetal force is always directed towards the center of the circle of motion that an object is traveling in.
When an object moves around the circular track the centripetal force is provided by?
In an automobile, the friction force of the tires allows the vehicle to follow a circular course, because the friction, or grip, of the tires resists the sideways, or outward force known as centrifugal force. In free space, an orbiting body has gravity acting to provide the centripedal force.
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.
