Centripetal force is defined as, “the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation,” while centrifugal force is defined as “the apparent force that is felt by an object moving in a curved path that acts outwardly away from the center of …

The centrifugal force is very real if you are in a rotating reference frame. However, the centrifugal force is an inertial force, meaning that it is caused by the motion of the frame of reference itself and not by any external force.

The Coriolis force is proportional to the rotation rate and the centrifugal force is proportional to the square of the rotation rate. The centrifugal force acts outwards in the radial direction and is proportional to the distance of the body from the axis of the rotating frame.

Currents Tutorial Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect. Click the image for a larger view. Coastal currents are affected by local winds.

The Coriolis effect is important to virtually all sciences that relate to Earth and planetary motions. It is critical to the dynamics of the atmosphere including the motions of winds and storms. In oceanography , it helps explains the motions of oceanic currents.

Despite the high power of a rifle shot, it is still affected by gravity. If you were to fire a sniper rifle level to the ground at the same moment that you drop a bullet from the barrel height, the fired bullet and the dropped bullet would hit the ground at the same time.

Yes, they have to correct because of the Coriolis effect. This phenomenon is due to earth’s rotation, and changes according to the hemisphere you are in. In the northern one the bullet will always drift to the right, in the southern hemisphere the bullet will be deflected to the left.

When a bullet is turned by the rifling, it gains angular momentum—— because it now gains a rotation from the rifling. Once it goes out of the barrel, it has a tendency to go forward, in one particular direction, instead of drifting around due to wind or gravity. The lands in the barrel causes the bullet to spin.

Bullets touch the inside of the gun’s barrel during normal operation. There’s rifling inside the barrel that’s supposed to impart spin on the bullet. So the barrel rubs grooves in the bullet (this is how CSI can match a bullet to a gun) but the softer bullet does little damage to the gun.

As a bullet spins clockwise it will slowly drift to the right, following the same logic if a bullet spins counterclockwise it will slowly drift to the left. This is caused by the bullets axis of rotation and the direction of the velocity vector of the center of gravity deviating as it spins through the air.

We think of bullets flying in perfectly straight lines—but nothing could be further from the truth. Over very short distances, bullets do follow more or less a straight line. Over longer distances, they follow a slight downward curve because gravity tugs them toward the ground as they go along.
