Homework Statement


True or false: "Torque cannot exist without a force acting on the body"


Homework Equations


t = force(rsin(theta))


The Attempt at a Solution


I can't find a reason to believe the statement is false. Look at the equation:
t = Frsin@, where the @ sin is theta, and F is force.

if F is 0, then t must equal zero, so I think the original statement, "Torque cannot exist without a force acting on the body" is true.
