Read each question carefully and answer to the best of your ability. Show all your work for calculation questions.
1. What is torque?
A force that causes linear motion
A twisting force that causes rotation
The resistance to motion
The rate of change of velocity
2. For an object to be in rotational equilibrium, the net torque acting on it must be:
Positive
Negative
Zero
Constant
3. The unit of torque in the SI system is the .
4. The perpendicular distance from the pivot to the line of action of the force is called the .
5. An object is in equilibrium when it is at rest and the net force and net torque acting on it are both zero.
6. A 10 N force is applied at a distance of 0.5 meters from the pivot point. Calculate the torque produced.
7. Explain the difference between stable, unstable, and neutral equilibrium with an example for each.
8. Observe the lever below. If the force (F1) is 20 N and the distance (d1) is 1.5 m, what force (F2) is required at a distance (d2) of 0.5 m to achieve rotational equilibrium?
9. Torque is a scalar quantity.
True
False
10. The center of gravity and center of mass are always at the same location for an object.
True
False
