it has constant radial and tangential acceleration. it has variable tangential and radial acceleration. it has only constant radial acceleration.
Q. What is critical condition in vertical circular motion?
In the vertical circular motion, the speed is lowest at the highest point whereas the speed is highest at the lowest point. Critical velocity is defined as the minimum velocity required by the mass at the highest point to complete the circular motion.

Q. What is meant by vertical circular motion?
Answer: In a vertical circle, a body spins in such a way that its motion at different points is different than the body’s motion is assumed to be vertical circular motion. Consider an object of mass m and wrapped in a stretchable string at one end whirled in a vertical circle of radius d.
Q. What is the critical speed of a body moving in a vertical circle of radius r?
Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. The velocity of a body moving in a vertical circle of radius r is √7gr at the lowest point of the circle.
Q. What is the minimum speed required at the bottom to perform a vertical loop?
So, the minimum speed, at the top, required to perform a vertical loop is 15.65 m/s. Was this answer helpful?
Q. Why does tension in a string become zero at the top of a vertical circle?
Since the tension force cannot become a force that points away from the circle, it must be that the minimum of T is 0. Therefore, to determine the minimum velocity needed at the top of the circle for circular motion to still occur, it must be that T=0.
Q. Is zero speed possible at the uppermost point under what condition s?
Yes, at the uppermost point, the zero speed is possible in the trajectory. The vertical velocity becomes zero under the conditions, where velocity direction completely stays horizontal and the acceleration remains downwards because of the gravity.
Q. Is zero speed possible at the uppermost point in vertical circular motion?
However, in a controlled vertical circular motion, e.g., those of a small body attached to a rod or the giant wheel (Ferris wheel) ride, the body or the passenger seat can have zero speed at the top, i.e., the motion can be brought to a stop.
Q. What happens when tension is 0?
It equals zero because the weight isn’t moving so the acceleration is zero. As you can see from the above equation, the tension transmits the force of gravity that acts on the weight, to a force acting on the hand. This is a general feature of massless strings, and is true even if there is acceleration.
Q. At what part of the circle is the string most likely to break?
Circular Motion in “Vertical” Circles tension is greatest at the bottom of the circular path. This is where the rope is most likely to break. It should make sense that the tension at the bottom is the greatest.
Q. When the ball reaches the break in the circle what is the direction of its acceleration?
and that the direction of the acceleration is inward toward the center of the circular path. This is illustrated in Figure 1.
Q. When the ball is at the top of the circle what is the tension in the string?
Thus, if you twirl the ball(s) at such a speed that at the top of the swing gravity provides the centripetal acceleration necessary to keep the ball(s) moving in a circle, the tension in the string at this point is zero, and below this speed gravity causes the ball(s) to take a flattened path at the top.
Q. Is dimensional formula of tension and surface tension same?
a) Tension and surface tension. Since tension is a type of force, it will also have the same dimensional formula as the dimensional formula of force i.e. [MLT-2].
Q. Is the dimensional formula for?
The equation obtained by equating a physical quantity with its dimensional formula is called a dimensional equation….Dimensions and Dimensional Formula.
Physical Quantity | Dimensional Equation |
---|---|
Force (F) | [F] = [M L T-2] |
Power (P) | [P] = [M L2 T-3] |
Velocity (v) | [v] = [M L T-1] |
Density (D) | [D] = [M L3 T0] |
Q. What is dimensional formula of radius of gyration?
So finally, the dimensional formula of the radius of gyration will be written as: [M0LT0].
