  2. Circular motion - Wikipedia

    en.wikipedia.org/wiki/Circular_motion

    This diagram shows the normal force (n) pointing in other directions rather than opposite to the weight force. In non-uniform circular motion, the normal force does not always point to the opposite direction of weight. Here, 'n' is the normal force. The normal force is actually the sum of the radial and tangential forces. The component of ...

  3. Normal force - Wikipedia

    en.wikipedia.org/wiki/Normal_force

    Figure 2: Weight (W), the frictional force (F r), and the normal force (F n) acting on a block.Weight is the product of mass (m) and the acceleration of gravity (g).In the case of an object resting upon a flat table (unlike on an incline as in Figures 1 and 2), the normal force on the object is equal but in opposite direction to the gravitational force applied on the object (or the weight of ...

  4. Newton's laws of motion - Wikipedia

    en.wikipedia.org/wiki/Newton's_laws_of_motion

    When a body is in uniform circular motion, the force on it changes the direction of its motion but not its speed. For a body moving in a circle of radius r {\displaystyle r} at a constant speed v {\displaystyle v} , its acceleration has a magnitude a = v 2 r {\displaystyle a={\frac {v^{2}}{r}}} and is directed toward the center of the circle.

  5. Centripetal force - Wikipedia

    en.wikipedia.org/wiki/Centripetal_force

    The resultant or net force on the ball found by vector addition of the normal force exerted by the road and vertical force due to gravity must equal the centripetal force dictated by the need to travel a circular path. The curved motion is maintained so long as this net force provides the centripetal force requisite to the motion.

  6. Fictitious force - Wikipedia

    en.wikipedia.org/wiki/Fictitious_force

    A classic example of a fictitious force in circular motion is the experiment of ... form as the normal centrifugal force ... (physics) Free motion equation;

  7. Tangential speed - Wikipedia

    en.wikipedia.org/wiki/Tangential_speed

    Tangential speed is the speed of an object undergoing circular motion, i.e., moving along a circular path. [1] A point on the outside edge of a merry-go-round or turntable travels a greater distance in one complete rotation than a point nearer the center. Travelling a greater distance in the same time means a greater speed, and so linear speed ...

  8. Moral Injury: The Grunts - The Huffington Post

    Some troops leave the battlefield injured. Others return from war with mental wounds. Yet many of the 2 million Iraq and Afghanistan veterans suffer from a condition the Defense Department refuses to acknowledge: Moral injury.

  9. Acceleration - Wikipedia

    en.wikipedia.org/wiki/Acceleration

    are called the tangential acceleration and the normal or radial acceleration (or centripetal acceleration in circular motion, see also circular motion and centripetal force), respectively. Geometrical analysis of three-dimensional space curves, which explains tangent, (principal) normal and binormal, is described by the Frenet–Serret formulas ...
