Torque starts at 11 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Torque.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A seesaw is balanced when two children of different masses sit at different distances from the pivot. This is an example of which principle?
Define torque and state its SI unit.
Describe the right-hand rule for determining the direction of torque.
Explain the difference between torque and force.
A force of 10 N is applied perpendicular to a wrench at a distance of 0.2 m from the pivot. Calculate the torque produced.
A force of 12 N is applied at a distance of 0.4 m from the axis, making an angle of 60° with the lever arm. Calculate the torque.
A force of 15 N is applied at a point 0.3 m from the axis of rotation, but at an angle of 0° to the lever arm. What is the torque produced?
A force of 18 N is applied at a distance of 0.25 m from the axis, perpendicular to the lever arm. What is the torque produced?
Which of the following does NOT affect the magnitude of torque? (1) Magnitude of force (2) Distance from axis (3) Mass of the object (4) Angle between force and lever arm

A couple produces a turning effect but no ________ motion.
If a force is applied parallel to the lever arm, the torque produced is _________.
If the angle between the force and the lever arm is 90°, the torque is _________.
The moment arm is defined as the ________ distance from the axis of rotation to the line of action of the force.
True or False: If the line of action of a force passes through the axis of rotation, the torque produced is zero.
True or False: The direction of torque is always perpendicular to the plane formed by the position vector and the force vector.
True or False: The direction of torque is determined by the right-hand rule.
True or False: The magnitude of torque depends only on the magnitude of the force applied.
