What is the relationship between torque and force in rotational motion?

In summary, torque is a measure of rotational force typically measured in units of Newton-meters or foot-pounds. It is different from linear force and is affected by factors such as the lever arm, magnitude of the force, and direction of the force. Torque is calculated by multiplying the force applied by the distance from the axis of rotation to the point where the force is applied. It has many real-world applications, including in car engines, bicycles, and engineering, physics, and mechanics fields.

If a problem asks for the force of torque that will stop something from rotating that will be equal(?) to the amount of torque implied in the problem?

The problem is probably asking for the torque of a force required to stop the object from rotating. Think about Newton's laws. What must be the sum of all torques in order for there to be no rotation?
 

1. What is torque?

Torque is a measure of the force that causes an object to rotate around an axis. It is typically measured in units of Newton-meters (N*m) or foot-pounds (ft-lb).

2. How is torque different from force?

Torque is a rotational force, while force is a linear force. Torque is the force that causes an object to rotate around an axis, while force is the push or pull that causes an object to move in a straight line.

3. What factors affect torque?

The factors that affect torque include the distance from the axis of rotation to the point where the force is applied (known as the lever arm), the magnitude of the force, and the direction of the force.

4. How is torque calculated?

Torque is calculated by multiplying the force applied by the distance from the axis of rotation to the point where the force is applied. The formula is: torque = force x lever arm.

5. What are some real-world applications of torque?

Torque is used in many real-world applications, including car engines, bicycles, and wrenches. It is also important in the fields of engineering, physics, and mechanics, and is used to measure the power of motors and engines.
