Which of the following is the correct definition of torque?
Which of the following is the correct definition of torque?
- The force that causes an object to rotate in a straight line
- The tendency of a force to turn or twist an object about an axis of rotation (correct)
- The force that causes an object to move in a circular path
- The measure of force that causes an object to accelerate in linear kinematics
What is the difference between static and dynamic torque?
What is the difference between static and dynamic torque?
- Static torque produces angular acceleration, while dynamic torque does not
- Static torque does not produce angular acceleration, while dynamic torque does (correct)
- Static torque is caused by a force that is not perpendicular to the axis of rotation, while dynamic torque is caused by a force that is perpendicular to the axis of rotation
- Static torque is caused by a force that is perpendicular to the axis of rotation, while dynamic torque is caused by a force that is not perpendicular to the axis of rotation

What is the moment arm or lever arm?
- The distance between the point of application of force and the axis of rotation (correct)
- The distance traveled by an object during rotation
- The force that causes an object to rotate about an axis
- The tendency of a force to turn or twist an object
