I’m pretty sure we have had this discussion before so i’ve got one of my old copypastas from a previous thread. >> Force travels through solid objects at roughly the speed of sound in that object‚ if you force a piece of an object to move at greater than the speed of sound through that medium it will simply tear whatever is holding it together without transmitting force to the surrounding structure. this gives a kind of hole punch effect if the projectile is moving faster than the speed of

Aerodynamics Parachutes work on the principles of gravity and air resistance and in effect‚ terminal velocity. Air resistance (air friction) Air resistance is an upward force exerted on a body while it is in the air and is the result of air molecules that come in contact with the surface of the falling object. This force attempts to counteract gravity and other downwards forces influencing a body. The amount of air resistance encountered by an object is dependent on two factors: speed of the object

Hypothesis: ‘If the sector size is the increase‚ then the terminal velocity will decrease.’ The reason is that if the sector size is bigger‚ the surface area of the cone will become smaller. If the surface area is smaller‚ than the friction will be less‚ so there will be less terminal velocity. Variables Table: Variables

In general PIT records obtained on piles without reinforcements exhibit a smooth record where the velocity has an initial impact pulse. Beyond this the curve tends to shift downward

balance of forces is reached and the skydiver no longer accelerates and then reaches terminal velocity. The cross-sectional area of the skydiver in the spread eagle position encounters more air resistance than a skydiver who assumes the pencil-dive position. The greater cross-sectional area of a skydiver in the spread eagle position leads to a greater air resistance and a tendency to reach a slower terminal velocity. Once the skydiver leaves the aircraft‚ or plane‚ they leave a projectile motion and could

Athletes who can perform at a fairly high velocity‚ or that can put objects in high velocity‚ tend to excel in their sport‚ especially power sports.
