The moment of a force about a point = force × perpendicular distance from the force line to the point. A couple is a pair of forces that are equal in magnitude but act in opposite directions produc ...

... Newton’s Second Law: Newton’s first law states that an object does not accelerate unless a net force is applied to the object. But how much will an object accelerate when there is a net force? The larger the force the larger the acceleration. Therefore acceleration is directly proportional to mass. ...

... When you push against a wall, or pull at it, you experience a force in the opposite direction. The harder you push (or pull), the harder the wall pushes (or pulls) back. In fact, the force exerted by the wall on you is exactly equal in magnitude and opposite in direction to the force exerted by you ...
