What are the similarities of friction and inertia?
Friction and inertia are both forces that resist motion. Friction occurs when two surfaces rub against each other, while inertia is the tendency of an object to resist changes in its state of motion. Both friction and inertia depend on the mass of the object and can affect its movement.
What is the use of moment of inertia?
moment of inertia is the rotational equivalent of mass. it is given by I= Mk2 moment of inertia in rotational motion play the same role as mass in linear motion, that is in linear motion f = ma while in rotation, torque= I*Angular acceleration where I is the moment of inertia
How is angular momentum expressed in polar coordinates?
Angular momentum in polar coordinates is expressed as the product of the moment of inertia and the angular velocity, multiplied by the radial distance from the axis of rotation. This formula helps describe the rotational motion of an object in a two-dimensional plane.
Two objects one heavy and one light travel at one of two speeds Which will have the most inertia?
The heavier object will have more inertia regardless of the speed at which they are traveling. Inertia is directly related to an object's mass, with heavier objects having greater inertia compared to lighter objects.
Can a scalar quantity be the product of 2 vector quantities?
No, a scalar quantity cannot be the product of two vector quantities. Scalar quantities have only magnitude, while vector quantities have both magnitude and direction. When two vectors are multiplied, the result is a vector, not a scalar.
What two quantities does rotational inertia depend on?
The mass, and how it is distributed- how far the masses are on average from the axis of rotation. However, it is the square of the distance that counts in this case.
What is the dimension of 27 83?
The answer will depend on (a) whet the dimensions of the two quantities are, and (b) what the missing operator between the two quantities is.
What are the similarities of friction and inertia?
Friction and inertia are both forces that resist motion. Friction occurs when two surfaces rub against each other, while inertia is the tendency of an object to resist changes in its state of motion. Both friction and inertia depend on the mass of the object and can affect its movement.
What shapes have rotational symetry?
A line has two fold rotational symetry.
How many rotational symmetry does a parallelogram have?
A general parallelogram has rotational symmetry of order two.
What is the use of moment of inertia?

What is the quotient of two quantities called?
The quotient of two quantities called a ratio.
A comparison of two quantities?
What is called a statement of comparing of two or more different quantities
What makes two quantities proportional?
Any two non-zero quantities are always proportional. If the two quantities are X and Y, they are proportional to X/Y.
What is the order of rotational symmetry of a rectangle?
Two.
A has two-fold rotational symmetry?
line
A line has rotational symmetry?
two-fold
