Final answer:
The moment of force, or torque, is the product of the force applied and the distance from the pivot point. It is important in mechanics, engineering, and physics.
Step-by-step explanation:
The moment of force, also known as torque, is defined as the product of the force applied and the distance from the pivot point to the point where the force is applied. It is calculated using the equation T = rF sin θ, where T is the torque, r is the distance, F is the force, and θ is the angle between the force and the lever arm.
For example, if you have a door and you push it at a point far from the hin_ges, it will be easier to open than if you push it near the hin_ges. This is because the distance from the pivot point affects the torque.
Understanding torque is important in various fields, including mechanics, engineering, and physics.
