- Centripetal force does not exist on its own as a standalone force, but rather it is a net force that acts towards the center of circular motion.
- Centripetal force is not a new or separate force but rather is provided by other forces in a system, such as tension, gravity, or friction.
- Centripetal force does not contribute to the speed of an object in circular motion, but rather acts to change the direction of motion.

What are some engaging centripetal force activities that can be used to demonstrate the concept in a hands-on way?
Some engaging centripetal force activities include swinging a bucket of water in a circle without spilling it, spinning a ball on a string around your hand, or riding a carousel and feeling the outward force pushing you towards the edge. These hands-on activities demonstrate how centripetal force keeps objects moving in a circular path.
How is centripetal force created?
You have a centripetal force whenever you have any force that attracts an object towards the center of its circular movement. In some cases, the centripetal force is what keeps an otherwise free object in a circular (or elliptical) trajectory in the first place - like when the Sun attracts the planets. In other cases - such as in a flywheel - the outer parts pull outwards (because of their inertia), so, by Newton's Third Law, the center of the movement pulls inward, providing the centripetal force. (If the outward pull is too strong, the objects that moved in a circular trajectory will break away.)
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.
When you are rounding a curve what force comes into play?
When rounding a curve, the centripetal force comes into play. This force is directed towards the center of the curve and is necessary to keep an object moving in a curved path rather than continuing in a straight line.
What are some common centripetal acceleration problems and how can they be solved?
Common centripetal acceleration problems include calculating the acceleration of an object moving in a circular path, determining the force required to keep an object in circular motion, and finding the speed of an object in circular motion. These problems can be solved using the centripetal acceleration formula, which is a v2 / r, where a is the centripetal acceleration, v is the velocity of the object, and r is the radius of the circular path. By plugging in the known values into this formula, one can solve for the unknown variable.
What is the reaction force to centripetal force in a centrifuge?
The centripetal force is the force with which the centrifuge pushes some object inwards. The opposite force, of course, is the object pushing the centrifuge outwards.
What are some examples of centripetal forces?
Centripetal force is a force that makes a body follow a curved path. An example of centripetal force is gravity making something in space orbit Earth. Mud flying in circles from a tire going down the road is centripetal force.
What kind of force that the tornado have like centripetal force centrifugal force?
Hi, Well the force is centripetal force during a body is initially attacked by the tornado,when the body started swinging in the tornado from the surface of the earth,the time when body covers some distance from downward to upward is the time when centrifugal force is applied.... That means tornado have both the centripetal force and centrifugal force..... Thanks you!
What sport involves the centripetal force?
A hammer thrower uses the centripetal force to control the hammer-head while its kinetic energy is built up for release
What is a gravitational pull also called?
gravitational force of attraction/gravity -- force -- weight -- centripetal force, under some circumstances

When you are in roller coaster you never fall down even when you are upside down Why?
It is true that the centripetal force is directed towards the center of the circle but in addition to the centripetal force there is another force called centrifugal force which is reaction force. The centrifugal force is directed opposite to the centripetal force, i.e.,outward. It is due to this force that we never fall down even when we are upside down. Technically, you are under the same downward acceleration at all times. When you are thrust up by the ride, it takes some time for the downward acceleration to stop the upward movement. That "some time" is your free upside-down ride.

What is the earth's centripetal force?
The term "centrifical" is a word without a definition; some would say a non-existent word. It might have the same definition as "ncauvjnscc" or "oioushc" or any other made up babble you chose to imagine. However, the term has been used enough in common parlance as to associate its meaning with either "centripetal" or "centrifugal". The centripetal force is the force applied to a linearly travelling (straight line) object to make it travel in a curve or to make it rotate about some center point. The force is applied to the object make it move toward that center point. The centrifugal force is referred to as the opposite force to the centripetal force following Newtons Law of equal and opposite reaction. However, this force is a consequence of the inertia of the object (resistance to the circular motion) and acts on the source of the centripetal force, NOT the object experiencing curved motion. The centrifugal force is equal, but opposite, the centripetal force. For instance, a weight on a string attached to an object swung about your head experiences a force applied inward (centripetal force) due to your hand (the center point) applying the force. The string also experiences this force all along its length. Your hand experiences a force applied outward (centrifugal force) due to the weights inertia (resistance to change direction at all points in time as it moves in a circle). The string also experiences this force all along the string. The opposing forces on the string keeps the string in tension. Additionally, your feet share a friction force against the surface you stand on equal to the centripetal force to keep you stationary. So the question remains: which force did you really mean, centripetal or centrifugal?
What statement is self -contradictory?
Statements that are self contradictory are paradoxes or oxymorons. Some are trivial some are funny. A funny one would be military intelligence or military music. A more serious one is the old one about an immovable object and an irresistible force

What are some properties that the moon and earth share?
both are planets and are orbit with centripetal force. think about the atmospheres. They orbit around one another.
