What makes a spinning top stay up?

When you spin a top into motion, you’re applying a force that converts the top’s potential (stored) energy into kinetic energy, or energy of motion. The principle of conservation of angular momentum holds that the top would keep spinning indefinitely if there were no other external forces acting upon it.

Why doesn’t water fall out of a bucket when you spin it?

Quick Physics: The water stays in the bucket because of inertia. The water wants to fly off from the circle, but the bucket gets in the way and keeps it in place. This is the same effect you feel when you go around a tight corner in the car and get squished against the door.

How long can a spinning top spin?

Nimrod explained that the motorised spinning top’s long-lasting spin is due to its small size and minimal energy consumption. Though the record attempt was stopped at just over 27 hours, Nimrod claims the spinning top can rotate for up to 30 hours.

Is a spinning top angular momentum?

The way the top spins around the rotation axis gives it angular momentum, and the angular momentum will remain constant until an external source of torque acts on the spinning top. Moment of inertia, also called “angular mass“, is the inertiaof a rotating body with respect to its rotation.

What happens when you swing the bucket slowly?

In order for the bucket to keep falling with the water, the bucket must travel fast enough to keep up with the water. If you spin the bucket too slowly, the water will fall out and you will get wet.

Is it possible to whirl a bucket of water fast enough in a vertical circle so that the water won’t fall out if so what is the minimum speed define all quantities needed?

In this case, the net force just equals the weight force, and since the bucket is moving in a circle, this net force must be the centripetal force. so the water will not fall out if the bucket is whirled around once every 2 s.

Do heavier tops spin longer?

Heavy tops spin for a longer time than light ones when launched at the same speed. The faster they’re spinning when launched, the longer they spin. The combination of mass and speed is known as momentum.

How can you tell if a bottle cap has been tamper evident?

The content of a bottle that is capped with a tamper-evident closure can be accessed only if the cap is fully rotated counter clockwise (i.e. opened). This rotation will snap the bridge, resulting in separation of cap from band. A broken bridge provides visible evidence of prior opening or tampering.

How do you put a bottle on the platen?

The bottle is placed on the platen and the user winds in the pegs to grip the bottle securely. To cancel any torque reading resulting from bottle placement, the user zeros (resets) the Tornado. The user then twists the cap and continues rotating it until the bridge is broken.

What is the difference between normal and slip spinners?

Normal spinners are of two types: Following slip (initial break) torque, the cap’s bridges do not break and the cap spins around the thread but is not separable from the bottle, resulting in a bottle whose cap is unscrewed but still attached.
