What is the minimum velocity with which a body must enter a vertical loop?

What is the minimum velocity with which a body must enter a vertical loop?

but to complete the circular motion or to form complete circular path then √5gl is the minimum velocity so by which at topmost point there will be no tension or normal but there will be √gl velocity which will allow body to continue its motion.

Is zero speed possible at the uppermost point under what conditions?

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.

What is the condition for the body to leave the circle in the looping loop?

Looping the circle condition: The body will loop the circle only if Tmin >= 0. mvA 2/r – mg >= 0. mvA 2/r >= mg which means vA >= (gr)1/2. The minimum value of velocity at the highest point is (gr)1/2. Similarly, at the lowest point L, applying the conservation of energy ½ mvB2 = ½ mvA2 + mg (2r)

Is centripetal force constant in vertical circular motion?

Motion in a Vertical Circle In this motion, the centripetal force, the force that points towards the center of a circle, is always constant.

What is a Loopty loop?

an airplane maneuver in which a plane, starting upward, makes one complete vertical loop. a ride in an amusement park that simulates this maneuver.

Why is it called loop the loop?

That loop of 5th Avenue (now Wells Street), Van Buren Street, Wabash Avenue and Lake Street was known as the Union Loop because of the Union Elevated Railroad company that operated it. …

How do you make a paper airplane that will loop?

How to Make a Loop De Loop Paper Airplane

1. Fold a sheet of regular printer paper in half like a hot dog and unfold it to make a crease.
2. Fold the top two corners so that they are aligned with the crease.
3. Fold the tip down and align the tip with the crease to make it look like a tall envelope.
4. Fold the top two corners to about 1cm above the tip.
5. Fold the tip up.

Why are loops on roller coasters not circular?

The answer is that there is a force (provided by the rails), that is pushing the trucks of the coaster towards the center of the loop. This force is called the Centripetal Force. The centripetal force is pushing the coaster around in a circle.

What is acceleration at the top of a loop?

For a rider moving through a circular loop with a constant speed, the acceleration can be described as being centripetal or towards the center of the circle. At the top, this would be in the downward direction and at the bottom of the loop it would be in the upward direction.
