All Flashcards
What is the effect of applying a torque to an object?
The object experiences angular acceleration.
What is the effect of increasing the distance from the axis of rotation when applying a force?
It increases the magnitude of the torque.
What happens when the net torque on an object is zero?
The object is in rotational equilibrium, meaning it has no angular acceleration.
What is the effect of shifting the axis of rotation away from the center of mass?
It increases the moment of inertia, as described by the parallel axis theorem.
What are the differences between translational and rotational equilibrium?
Translational Equilibrium: Net force is zero, no linear acceleration. | Rotational Equilibrium: Net torque is zero, no angular acceleration.
What are the differences between force and torque?
Force: Linear push or pull, causes linear acceleration. | Torque: Rotational force, causes angular acceleration.
What are the differences between mass and moment of inertia?
Mass: Resistance to linear acceleration, scalar quantity. | Moment of Inertia: Resistance to angular acceleration, depends on mass distribution, scalar quantity.
What is the definition of Torque?
Torque is the rotational equivalent of force, causing an object to rotate around an axis. It's a vector quantity measured in Newton-meters (N·m).
What is Translational Equilibrium?
Translational equilibrium occurs when the net force acting on an object is zero, meaning the object is not accelerating linearly.
What is Rotational Equilibrium?
Rotational equilibrium occurs when the net torque acting on an object is zero, meaning the object is not accelerating angularly.
What is Moment of Inertia?
Moment of Inertia (I) is an object's resistance to changes in its rotational motion. It depends on mass distribution around the axis of rotation.
What is the Parallel Axis Theorem?
The parallel axis theorem calculates the moment of inertia about an axis parallel to one that passes through the center of mass, using the formula .
