KEY TAKEAWAYS •
Torque is a force that causes a twisting motion or that leads to the twisting of an object on an axis.
•
Torque is directly proportional to the force applied and the distance from the pivot point.
•
Torque can be clockwise or counterclockwise when it comes to its direction.
•
Things like angular velocity and angular momentum are equivalent to the linear velocity and momentum.
•
The moment of inertia varies with the object but is related to the mass and inversely proportional to the radius squared.
•
Angular momentum is always conserved in any collision equations.
•
Kinetic energy can be rotational or translational so that rotational kinetic energy will take away from translational kinetic energy of an object that does both rotation and linear displacement.
•
The direction of the angular momentum and velocity will be upward if the object is spinning counterclockwise.
