Rotational Equilibrium

These flashcards encompass key concepts related to rotational equilibrium, including definitions of terms that are critical for understanding the principles of torque and balance in physics.

Torque

The measure of the force that causes an object to rotate.

Fulcrum

The pivot point around which a lever rotates.

Rotational Equilibrium

A condition in which an object does not rotate because the sum of the torques acting on it is zero.

Principle of Moments

In equilibrium, the sum of clockwise moments about a pivot is equal to the sum of counterclockwise moments.

Lever

A rigid bar that pivots or rotates around a fulcrum.

Meter stick

A tool used to measure length, commonly 1 meter long and often used in physics experiments.

Weight

The force exerted on an object due to gravity, typically measured in newtons (N) or pounds (lb).

Support Force

The upward force exerted by a surface to support the weight of an object resting on it.

Counterclockwise (C.C.W.)

A direction of rotation that is opposite to the direction of the hands of a clock.

Equilibrium Condition

A state of balance where the net force and net torque acting on an object are both zero.
