Inertia Depends On Mass Rotational Inertia Depends On Mass And Something Else. What??
Inertia depends on mass rotational inertia depends on mass and something else. … The center of mass of a baseball is at the center. The center of gravity of a baseball is at the center. The center of mass and gravity for a baseball bat are closer to the bat head where there is more mass.
What does rotational inertia depend on?
Does inertia depend on mass distribution?
Moment of Inertia depends on both the mass and the distribution of the mass. Further away from the axis of rotation a unit of mass will cause a greater moment of inertia.
What is the relationship between the center of gravity and the support base for an object that is in stable equilibrium quizlet?
What is the relationship between the center of gravity and the support base for an object that is in stable equilibrium? A vertical line through the center of gravity must pass through the support base.
How does mass affect inertia?
All objects resist changes in their state of motion. … The more inertia that an object has the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.
How does mass and radius affect rotational inertia?
Rotational inertia is a scalar not a vector and is dependent upon the radius of rotation according to the formula rotational inertia = mass x radius^2. … So the formula that we’re going to use for rotational inertia is i that’s the symbol rotational inertia equals the mass times the radius squared.
What are the factors affecting the moment of inertia?
The moment of inertia of a body is directly proportional to its mass and the distance of the particles of the body from the axis of rotation. Hence the moment of inertia depends on mass and distance from the rotating axis and force and density do not affect the moment of inertia of a body.
Is rotational inertia the same as moment of inertia?
Moment of inertia is the name given to rotational inertia the rotational analog of mass for linear motion. It appears in the relationships for the dynamics of rotational motion. The moment of inertia must be specified with respect to a chosen axis of rotation.
What two factors determine the moment of inertia of an object?
- The density of the material.
- Shape and size of the body.
- Axis of rotation (distribution of mass relative to the axis)
How does inertia depend on mass example?
The body of larger mass that will have less acceleration than the other body. That is how mass provides nature to resist the change in its state i.e. the inertia of the body. For example it is very difficult to move a heavy boulder (large mass) because its mass is very large and thus the inertia is more.
Which depends on the mass of the object?
As we know that the weight of an object is the product of mass and gravity so from this we can say that weight depends upon the mass of the object and the acceleration due to gravity.
Does moment of inertia depend on center of mass?
The moment of inertia depends not only on the mass of an object but also on its distribution of mass relative to the axis around which it rotates.
How can gravity be simulated in an orbiting space station?
How can gravity be simulated in an orbiting space station? Gravity can be simulated in a space station by spinning it. … The moon “falls” because it is being pulled in by the earth’s gravity while it is moving forward.
What is the law of inertia for rotating systems?
Torque tends to increase the rotational inertia of the object. B. Torque tends to increase the linear speed of the object. C. Torque tends to twist or change the state of rotation of the object.
How does the rotational speed of the smaller wheel compare with that of the larger wheel?
How does the rotation speed of the smaller wheel compare with that of the larger wheel? … The smaller wheels rotates twice as fast as the larger one in order to keep up with it. The tangential speeds are the same.
Why does mass affect rotational inertia?
It requires more efforts for larger mass to set up into the rotation. Thus moment of inertia depends upon mass. It is not equally easy to rotate both of them about the same axis of rotation. More efforts are required for the object at a greater distance to accelerate to the same angular velocity.
What causes inertia?
The inertia is directly proportional to the mass of the object/body that is the greater the mass of the body/object the greater will be the inertia possessed by that object/body. … The cause of inertia is the resistance offered by the body/object to change in its state of rest or motion.
What is inertia What gives the measurement of inertia?
The more the inertia of an object the more mass it has. Thus an object with more mass has a greater tendency to resist changes in its state of motion. The mass gives the measure of intertia.
How does the rotational inertia of a disk depend on its radius?
By increasing the radius from the axis of rotation the moment of inertia increases thus slowing down the speed of rotation.
Does inertia depend on radius?
Moment of inertia is directly proportional to the square of the radius.
Does mass affect rotational acceleration?
The greater the force the greater the angular acceleration produced. The more massive the wheel the smaller the angular acceleration.
Why is moment of inertia also called rotational inertia?
Moment of inertia is also called rotational inertia because it is a measure of the “resistence” of an object to be accelerated in its rotation. An object with a big moment of inertia is more difficult to increase/decrease its angular velocity (speed of rotation) than an object with a low moment of inertia.
On what factors does moment of inertia depends and find moment on inertia of a rod?
Moment of inertia depends on both mass and its distribution relative to the axis of rotation.
On which of the following does the moment of inertia depend?
How do you find inertia with mass and velocity?
Multiply the mass of the object with the acceleration of the object to get the translational inertia. Translational inertia is a measure of the resistance or opposing force offered by the object in motion when it subjected to a net external force.
What do you understand by mass moment of inertia explain clearly?
Mass moment of inertia also known as rotational inertia is a quantity that is used in measuring a body’s resistance to a change in its rotation direction or the angular momentum. It basically characterizes the acceleration undergone by an object or solid when torque is applied.
Does moment of inertia depend on shape?
Angular velocity. Hint: Moment of Inertia is a rotational analogue for mass. The moment of inertia is proportional and depends upon the mass distribution axis of rotation and the shape of the object. … Also Moment of inertia varies with the shape of the object.
On what factors does inertia of an object depend?
Inertia depends on density and mass. Inertia is directly proportional to mass and density of an object.
On which of the following factors does the moment of inertia of an object not depend upon?
Solution(By Examveda Team)
Moment of inertia depends on distribution of body axis of rotation and mass of the body. It is not dependent on angular velocity of the body.
On which factor does inertia of a body depends?
The inertia of a body depends on the mass of the body.
Which has greater inertia?
Explanation: The inertia of an object is its resistance to change its position if not in motion or its resistance to changing its motion for a moving object. Inertia is a definition of mass so an object with greater mass will have greater inertia.
Does inertia depend on velocity?
No inertia does not depend on speed. Inertia solely depends on the mass. The more mass the more inertia.
Does mass depend on material?
Mass is a measure of the amount of material in an object directly related to the number and type of atoms present in the object. Mass does not change with a body’s position movement or alteration of its shape unless material is added or removed.
