Q. In rotational dynamics, what is the moment of inertia?
A.
The rotational analog of mass.
B.
The torque applied to an object.
C.
The angular velocity of an object.
D.
The linear momentum of an object.
Solution
The moment of inertia is the rotational analog of mass, representing how difficult it is to change the rotational motion of an object.
Correct Answer:
A
— The rotational analog of mass.
Q. What is the gravitational potential energy of an object at height h?
A.
PE = mgh
B.
PE = 1/2 mv^2
C.
PE = Fd
D.
PE = mv
Solution
The gravitational potential energy of an object at height h is given by PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
