What center-directed continuously changes the direction of an object to make it move in a circle?
A centripetal force is a center-directed force that continuously changes the direction of an object to make it move in a circle. It is responsible for keeping the object moving in a curved path, as it pulls or pushes the object towards the center of the circle. This force is necessary to counteract the natural tendency of an object to move in a straight line.
Is it possible that the velocity of a body changes and its acceleration remains constant?
The definition of acceleration is: Any change of velocity, that is, speed or direction of motion. If an object is undergoing constant acceleration, then the definition says that its velocity must be changing.
Can you explain centripetal force?
Centripetal force is a force that makes a body follow a curved path: it is always directed orthogonal to the velocity of the body, toward the instantaneous center of curvature of the path.I linked my source.
What is the direction of acceleretion of a body in circular motion?
-- The acceleration is directed from the body to the center of the circle. -- The velocity is tangent to the circle at the place where the body is. That direction is also perpendicular to the acceleration at that moment.
What center directed force continously changes the direction of an object to make it move in a circle?
Centripetal force, which can be supplied by gravity, a string, friction (e.g. between tires and the road), etc.
In uniform circular motion quantities are constant?
In uniform circular motion, the speed of the object remains constant, but the velocity changes direction continuously. The acceleration is directed towards the center of the circle (centripetal acceleration) and its magnitude remains constant. The object moves in a circular path at a constant speed.
What is Going around on a Ferris wheel without stopping an example of?
Going around on a Ferris wheel without stopping is an example of uniform circular motion. In this type of motion, an object moves in a circular path at a constant speed, maintaining a constant distance from the center of the circle. While the speed remains constant, the direction of the object's velocity changes continuously, resulting in centripetal acceleration directed toward the center of the circle.
Why does circular motion always involve acceleration?
Circular motion involves acceleration because even if the speed remains constant, the direction of the velocity changes continuously, leading to acceleration. This acceleration, called centripetal acceleration, is always directed towards the center of the circle and is necessary to keep an object moving in a circle.
An object in circular motion is constantly acceleratingtrue or false?
True. It is accelerating because the velocity constantly changes. The velocity constantly changes because the direction changes - and a velocity is made up of a magnitude, and a direction.True. It is accelerating because the velocity constantly changes. The velocity constantly changes because the direction changes - and a velocity is made up of a magnitude, and a direction.True. It is accelerating because the velocity constantly changes. The velocity constantly changes because the direction changes - and a velocity is made up of a magnitude, and a direction.True. It is accelerating because the velocity constantly changes. The velocity constantly changes because the direction changes - and a velocity is made up of a magnitude, and a direction.
What direction is weight acting on an object?
Weight acts in the direction of the gravitational force exerted on an object, which is always directed towards the center of the Earth.
Why is circular motion an example of constant acceleration?
Actually it isn't. In circular motion, even if you assume a constant speed (the simplest case), acceleration is towards the center. Therefore, the direction of the acceleration changes all the time - and therefore, the acceleration changes all the time.
What is force causes an object to move in circular motion?
The centripetal force is responsible for making an object move in circular motion. It is directed towards the center of the circle and keeps the object continuously changing its direction. Without the centripetal force, the object would move in a straight line tangent to the circle.
