Torque is a measure of the force that can cause an object to rotate around an axis. It is calculated by multiplying the force applied to the object by the distance between the axis of rotation and the point of application of the force.
Question 2:Torque is directly related to rotational motion. The greater the torque applied to an object, the greater its rotational acceleration will be. This is described by Newton's Second Law, which states that the net torque on an object is equal to the moment of inertia times the angular acceleration.
Question 3:While both torque and force are measures of a physical interaction, they are not the same thing. Force is a vector quantity that describes the push or pull on an object, while torque is a vector quantity that describes the ability of a force to rotate an object around an axis.
Question 4:The distance from the axis of rotation, also known as the lever arm, is a crucial factor in determining the torque applied to an object. The longer the lever arm, the greater the torque will be for a given force. This is why a lever or wrench with a longer handle is easier to use, as it allows for more torque to be applied to a bolt or nut.
Question 5:There are many examples of torque in everyday life, such as using a wrench to loosen a bolt, opening a door, or riding a bike. Other examples include the rotation of an engine's crankshaft, the spinning of a top, and the swinging of a pendulum. Understanding torque is crucial in various fields, including engineering, mechanics, and sports.
