Why Does A Hollow Sphere Have More Rotational Kinetic Energy? Therefore, the rotational kinetic energy will depend on the moment of inertia. But the answer says that since the hollow cylinder has greater moment of inertia, it has greater rotational kinetic energy. Why do hollow objects have more rotational inertia? (Although they have the same
Which Body Does Not Have Centre Of Mass With Body? Explanation: because pencil sphere and dice are solid objects bat Bangle is not. Which body does not have Centre of mass with in body? Explanation: because pencil sphere and dice are solid objects bat Bangle is not. What is the Centre of mass of body?
What Relates The Torque On A Playground Merry-go-round To The Resulting Angular Acceleration? What relates the torque on a playground merry-go-round to the resulting angular acceleration? the merry-go-round’s rotational inertia. A force causes an object to rotate. How do you find angular acceleration from torque? If more than one torque acts on a rigid body
Why Do You Spin Faster When Your Arms Are Closer To Your Body? If you’re initially rotating with your arms outstretched, then when you draw your arms inward, your moment of inertia decreases. This means that your angular velocity must increase, and you spin faster. Why does pulling your legs in make you spin faster?
Does Angular Speed Depend On Mass? Angular velocity is just the angle the mass rotates in an interval of time. … So for the case of the object of mass m at radius r, I = mr2. This shows how the rotational inertia depends not only on the mass, but where the mass is located
What Is The Direction Of Velocity In Circular Motion? We will see that unlike linear motion, where velocity and acceleration are directed along the line of motion, in circular motion the direction of velocity is always tangent to the circle. This means that as the object moves in a circle, the direction of the velocity
Can A Body In Translatory Motion Have Angular Momentum Explain? Yes, a body in translatory motion can have angular momentum, unless the fixed point about which angular momentum is taken lies on the line of motion of the body. Can a body in linear motion have angular momentum? Angular momentum of a spinning object without
What Is The Direction Of Velocity Of An Object Moving Along A Circular Path Class 9? As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle. Since the direction of the velocity vector is the same as the direction of the
Why Does The Angular Velocity Decrease With Time? Since the rotational inertia of the system increased, the angular velocity decreased, as expected from the law of conservation of angular momentum. In this example, we see that the final kinetic energy of the system has decreased, as energy is lost to the coupling of the flywheels.
Can A Point Mass Have Angular Momentum? The Open Door Web Site : IB Physics : ANGULAR MOMENTUM OF A POINT MASS. Which means that the angular momentum of a point mass is equal to its linear momentum multiplied by its perpendicular distance from the point considered. Can a particle have angular momentum? (Figure) shows
