Do all points along the minute hand of a clock experience the same centripetal acceleration?

no. cause the angle apeed is differet in each point of the minute hand.
a=w*w*r. SO, the centripetal acceleration is different.

If the plotted points on a speed time graph do not form a straight line what do you know about the objects acceleration?
You can conclude that the acceleration of the object is not constant.

What is the acceleration between 7 and 7?
It looks as if you don't have enough information. To determine the average acceleration between two points in time, you need to know the beginning velocity, the ending velocity, and how much time elapsed.
How can you use a graph to show acceleration?
With great difficulty. Acceleration is a vector and that means that it has a direction as well as a magnitude (size). For motion in a plane, the only effective way to show acceleration is to draw lots of arrows from points at regular intervals in a plane such that the length of the arrow is a measure of the magnitude of the acceleration and the direction of the arrow coincides with that of the acceleration. An answer referring to a speed-time graph is totally incorrect. That measures speed in the radial direction only. All apects of motion (displacement, speed, acceleration) in a transsverse direction are completely ignored.
What type of angle would be formed by a clock's hands when it is 3?
The hands form a right angle. At 3 o'clock, the minute hand points straight up, and the hour hand points straight to the right.
When an object experiences centripetal acceleration in which direction does it acceleration?
Centripetal acceleration always points towards the center of the circular path that the object is following.
Which direction does the centripetal acceleration point?
The centripetal acceleration points towards the center of the circular motion. It is responsible for keeping an object moving in a circle by continuously changing the object's direction.
What is centripetal acceleration and find its magnitude and direction in the case of uniform circular motion?
Centripetal acceleration is the acceleration that points towards the center of a circular path. Its magnitude is given by a = v^2 / r, where v is the speed of the object and r is the radius of the circle. The direction of centripetal acceleration is towards the center of the circular path.
What describes acceleration involving only a change in direction?
Acceleration involving only a change in direction is known as centripetal acceleration. This type of acceleration occurs when an object moves in a circular path and constantly changes its direction. Centripetal acceleration points towards the center of the circle and is perpendicular to the object's velocity.
What is the corresponding number of revolutions per minute of the pedestal?
As your arms are moving in a circle, the tension in your arms not only needs to balance the weight of your arm, but also needs to generate the centripetal acceleration that keeps your arms in a circular track. Keep in mind that the centripetal acceleration acts at the c.o.g. of your arm and points straight inward along the x-direction towards the rotation axis and not upward along your arm.
What is a acceleration in a circle?
Acceleration in a circle is the change in velocity of an object moving in a circular path. It can be either centripetal acceleration, which points towards the center of the circle and keeps the object on its path, or tangential acceleration, which changes the speed of the object along the circle.
Are examples of centripetal acceleration?
Roulette. The ball going in a circle is an example of centripetal force, its speed (whatever it may be) is constantly changing so it is Acceleration. In other words, it is Centripetal Acceleration.A woman walking her dog around an oval jogging path.A race car on a curved stretch of track.
What kind of acceleration travels at a constant speed in a circular motion?
In circular motion, the centripetal acceleration points towards the center of the circle and is responsible for maintaining the object's direction. This acceleration does not change the object's speed, but instead changes its direction, keeping it in circular motion.
When an object moves in a circular path will the velocity change will there be acceleration?
The velocity of an object moving in a circular path will change because the direction of the velocity vector is constantly changing. This change in velocity indicates that there is acceleration present, known as centripetal acceleration, which always points towards the center of the circular path.
Centripetal forces always point?
In the case of circular movement, the centripetal force points towards the center of the circle.
When an object moves in a circle what acts to accelerate the object toward the center of circle?
The centripetal force acts to accelerate the object toward the center of the circle. This force is directed inward and is necessary to keep the object moving in a circular path. It is provided by tension, friction, gravity, or any other force that points towards the center of the circle.
What is the acceleration of an object moving in circular path at constant velocity?
The acceleration of an object moving in a circular path at constant velocity is directed towards the center of the circle and is called centripetal acceleration. This acceleration is responsible for changing the direction of the object's motion, keeping it moving in a circular path. The magnitude of the centripetal acceleration is given by the equation a = v^2 / r, where v is the velocity of the object and r is the radius of the circle.
