Newton's second law is valid only in inertial reference frames.

Indicate whether the statement is true or false

Question 2

Jane says that the magnitude of the torque exerted by a force of magnitude F is equal to the perpendicular distance from the axis of rotation r multiplied by F,

while Jason insists that it is equal to the distance from the axis of rotation r multiplied by the magnitude of the perpendicular component of the force, F. Who is right?

Answer to Question 1

TRUE

Answer to Question 2

They are both right. Both answers are equivalent to = F r sin, where is the angle between the force and the radial line.
