FAQs on Basic Introduction to Torque Video Lecture - Physics for EmSAT Achieve

1. What is torque?
Ans. Torque is a measure of the rotational force applied to an object around an axis. It is calculated by multiplying the force applied by the distance from the axis of rotation.
2. How is torque different from force?
Ans. While force is a linear push or pull applied to an object, torque is a rotational force applied around an axis. In simpler terms, force causes linear motion, while torque causes rotational motion.
3. What are the units of torque?
Ans. The SI unit of torque is Newton-meter (Nm). In the Imperial system, torque is measured in pound-feet (lb-ft) or foot-pounds (ft-lb).
4. How is torque related to power?
Ans. Torque and power are related through the equation: Power = Torque x Angular velocity. In other words, power is the rate at which torque is applied over time.
5. How can torque be increased in a system?
Ans. Torque can be increased by either applying a greater force or by increasing the distance from the axis of rotation. This can be achieved by using longer levers or increasing the force applied to the object.
