Torque and Rotational Kinematics

torque

a force that causes rotation

Torque formula

T=Fr sin0

r

The perpendicular distance from the axis of rotation to a line drawn along the direction of the force

S.I. unit of torque

Nm

positive torque

negative torque

counterclockwise

clockwise

the most torque is possible by applying a force

perpendicular

Fulcrum

the pivot point (not always the center of mass)

net torque/ sigma torque

The sum of all torque acting on an object

Angular velocity

change in displacement/change in time

angular acceleration

change of velocity/change in time

linear velocity and angular velocity

v=rw
