Name: Gyroscope toy
category:science toy
Introduction:
Gyroscope physics is one of the most difficult concepts to understand in simple terms.But as it turns out, there is a fairly straightforward way of understanding the physics of gyroscopes without using a lot of math. A gyroscope consists of a spinning mass, mounted so its axis of rotation can change.
Key Words:
✰Rotational dynamics:angular displacement, angular speed and , angular acceleration, and kinetic energy of an object rotating about an axis.
✰Angular Momentum:the quantity of rotation of a body, which is the product of its moment of inertia and its angular velocity.
✰Angular Momentum:the quantity of rotation of a body, which is the product of its moment of inertia and its angular velocity.
✰Angular speed : is a scalar measure of rotation rate.
✰Angular velocity :the rate of change of angular position of a rotating body.
✰Kinetic energy : is the energy of motion.
Materials:
✔-Gyroscopes
✔-String (White Cotton String)
✔-A Cup or somewhere were it can balance while rotating

------------------------------------------
Safety Procedures:
✤Just be careful while doing the experiment.
Procedures:
1. Have your gyroscope ready
2. Rap the sting on the top art of the gyroscope
3. After doing step # 2 ,let go of the string
4. Place the gyroscope either on the edge of a cup or on a table (Flat)
5.Observe how it rotates
6.Do it again if you desire
Formulas:
Angular Momentum:
(Where L is the angular momentum,
I is moment of inertia of the rotating body about axis of rotation,w is the angular velocity)
Linear momentum
In terms of linear momentum is given by :
L = mvr sin θ
(Where r is the radius of the body from the axis passing through center
p is the linear momentum
x denotes the cross product)
