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 else can I help you with?
What happens to the size of the centripetal force due to gravity acting on the satellite if the satellite moves farther from earth?
The centripetal force due to gravity decreases as the satellite moves farther from Earth because the force of gravity weakens with distance. This is in accordance with the inverse square law, which states that the force of gravity decreases with the square of the distance between two objects.
How can centripetal force affects a person on a playground swing?
Centripetal force is responsible for keeping a person on a swing moving in a circular path. As the swing reaches the highest point in its arc, the tension in the chains provide the centripetal force necessary to keep the person moving in a circular motion. When the swing is at its lowest point, the tension in the chains decreases as the centripetal force needed is also reduced.
Factors that affect tha increase of centripetal force in uniform circular motion?
Centripetal force increases with an increase in the speed or radius of the circular motion. It is inversely proportional to the radius of the circle and directly proportional to the square of the velocity. Generally, any factor that increases the velocity or decreases the radius will increase the centripetal force.
What is the symbol for centripetal force?
The symbol for centripetal force is "Fc".
How centripetal force equals to gravitational force?
The centripetal force is equal to the gravitational force when a particular body is in a circle. For a body that is in an orbit, the gravitational force is equivalent to the centripetal force.
How is the centripetal force affected by the mass and the radius?
Centripetal force as well as centrifugal force is given by the expression F = m v2 / r Hence F is directly proportional to the mass of the body but inversely related to the radius of the curvature So higher the mass more centripetal force in needed Lesser the radius, more centripetal force is required.
What factors are true about centripetal force?
Centripetal force is a force that is required to exist to have a circular motion. Thus the centripetal force can be any force that is able to accomplish this task. Examples of centripetal forces are the gravitational force, the electromagnetic force, the frictional force, or the constraint forces. The centripetal force depends on the system that is involved in be in a spin of a rigid body, or of a planetary motion, etc. Each particular system that requires a rotation or a spin needs to have a corresponding centripetal force.
Ask us of the following is true about centripetal force Check all that apply.?
Centripetal force is the force that keeps an object moving in a circular path. Centripetal force always acts in the direction of the center of the circle. Centripetal force is a real physical force that pulls objects radially inward. Centripetal force is necessary to maintain circular motion.
What do you call any force pulling toward the center of a circle?
That is called a centripetal force.
How does centripetal force affect centripetal force?
Centripetal acceleration is proportional to the square of the speed (a = v2/r). Therefore, according to Newton's Second Law, centripetal force is also proportional to the square of the speed.
What happens when speed of centripetal force is doubled?
If the speed of the centripetal force is doubled, the required centripetal force also doubles to keep the object moving in a circular path at that speed. The centripetal force needed is directly proportional to the square of the speed, so doubling the speed results in a quadrupling of the centripetal force required.
What is true about centripetal force Check all that apply.?
Centripetal force always acts inward towards the center of rotation. Centripetal force is required to keep an object moving in a circular path. Centripetal force is a real physical force acting on an object in circular motion. Centripetal force can be provided by tension, friction, or gravitational attraction.
