What is the difference between linear impulse and angular impulse?
Linear Impulse: Change in linear momentum due to a force over time. | Angular Impulse: Change in angular momentum due to a torque over time.
What is the difference between linear momentum and angular momentum?
Linear Momentum: Mass in motion in a straight line. | Angular Momentum: Tendency of an object to keep rotating.
Define angular momentum.
The 'rotational oomph' of an object; the tendency of a rotating object to keep rotating.
What is moment of inertia?
A measure of how hard it is to change an object's rotation.
Define angular velocity.
How fast an object is spinning.
What is torque?
Rotational force that causes things to rotate.
Define angular impulse.
The product of torque and time; what changes an object's angular momentum.
What is net torque?
The sum of all torques acting on an object.
What is angular acceleration?
The rate of change of angular velocity.
In the right-hand rule diagram for angular momentum, what do the fingers, curl, and thumb represent?
Fingers: direction of , Curl: direction of , Thumb: direction of
