Knowing the wheelbase (ℓ) and weight distribution, we can calculate the longitudinal location (a and b) of the center of gravity (CG). Then we blatantly ignore every safety warning on our lift to set the rear wheels onto homemade platforms and weigh the front axle (WF) in this tilted...
Step 1:The wind blows the ball horizontally - this will give the x-component of acceleration: {eq}A_x=5\frac{m}{s^2} {/eq}. Gravity acts in the vertical direction- this will contribute to the y-component of acceleration: {eq}A_y=9.8\frac{m}{s^2} {/eq}. ...
To launch, the pilot must run down a slope to get air moving across the wing at about 15 to 25 miles per hour (24 to 40 kph). This movement of air over the surface of the wing generates lift, the force that counters gravity and keeps the glider aloft. Once aloft, gravity (the we...

of the object hitting the ground, because the force drawing the object toward it (usually gravity) is exactly offset by the tangential (linear) acceleration described by the first equation in this section. If **ac were not equal to a**, the object would either fly off into...
Add in factors such as vehicle weight, gravity, and traction and you are looking at a braking distance of close to 300 feet or the length of a football field before you'll come to a complete stop [source: Edmunds]. Testing your vehicle's braking distance can be the difference between a...
The parachute valve, from the inside of the balloon. A Kevlar cord runs from the valve at the top of the balloon, down to the basket, through the center of the envelope. CargoLifter Hot air balloons also have a cord to open the parachute valve at the top of the envelope. When ...
He also formulated the theory of gravity, among his many other contributions to science and mathematics. Bettmann/Getty Images Next to E = mc², F = ma is the most famous equation in all of physics. Yet many people remain mystified by this fairly simple algebraic expression. It's ...
How To Calculate Force Kevin BeckUpdated marchmeena29/iStock/GettyImages The wordforceappears in practically every imaginable aspect of daily life, from sports to weather to military conflicts. But fundamentally, force is a concept rooted in physics, where is has a very specific and critical ...
I want to change the springs on my 2008 Saturn Sky to increase the natural frequency (NF) and lower the center of gravity (CoG). The stock front spring has a spring rate of 128 lbf/in, a free length of 15 inches and a compressed length of 10 inches. The spring I've selected has...
