Picture a ball on a string being whirled about the head of an experimenter. If the string breaks, the centripetal force disappears. The ball leaves on a tangent path form its (previous) circular path. Yes, it's that simple. The string provided centripetal force, by virtue of its tensile strength, to the ball to keep that ball moving in a circle. When the string broke, there was no force left to accelerate the ball "in" and keep it moving in an arc.
What else can I help you with?
Does the centripetal force acting on an object in uniform circular motion do work on the object?
No
Is centripetal force is acting when ab body is moving in stright line?
No, centripetal force is not acting when a body is moving in a straight line. Centripetal force is required to keep an object moving in a curved path.
What is the relationship between the normal force and the centripetal force acting on an object in circular motion?
In circular motion, the normal force is the force exerted by a surface on an object to prevent it from falling through. The centripetal force is the force that keeps an object moving in a circular path. The normal force and the centripetal force are related because the normal force provides the centripetal force needed to keep the object in circular motion.
What provides the centripetal force that keeps an object moving in a circular path?
The centripetal force that keeps an object moving in a circular path is provided by the inward force acting towards the center of the circle.
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.
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.
What factors are not true about centripetal force?
Centripetal force is not a distinct force but rather the net force acting on an object moving in a circular path. It is always directed towards the center of the circle and is required to keep an object moving in a circular path. It does not have its own cause but arises as a result of other forces acting on the object.
What is the significance of including a free body diagram (FBD) when analyzing the centripetal force acting on an object?
Including a free body diagram (FBD) when analyzing the centripetal force acting on an object is significant because it helps to visually represent all the forces acting on the object. This allows for a clearer understanding of how these forces contribute to the centripetal force required to keep the object moving in a circular path. By breaking down and analyzing the forces in a systematic way, the FBD helps in accurately determining the magnitude and direction of the centripetal force needed for the object's circular motion.
Is it true that projectiles are always affected by centripetal force?
No, projectiles are not always affected by centripetal force. Centripetal force only comes into play when there is circular motion involved. In the case of projectiles, the force of gravity is the dominant force acting on the object.
What is the origin of centripetal force?
The concept of centripetal force originates from Sir Isaac Newton's laws of motion, particularly his second law which states that a force is required to accelerate an object. Centripetal force is the force that acts on an object moving in a circular path, directed towards the center of the circle, and is required to keep the object in its circular motion.
What does a centripetal force free body diagram illustrate?
A centripetal force free body diagram illustrates the forces acting on an object moving in a circular path, showing the inward force required to keep the object moving in a curved trajectory.
What is the inward force on an object?
The inward force on an object is the force acting towards the center of the object. This force is required to keep an object moving in a circular path and is known as centripetal force. It is responsible for changing the direction of an object's velocity without changing its speed.
