Key Takeaways

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.
