This lady flipping pancakes demonstrates how potential and kinetic energy are transformed into each other but the total energy remains the same.
On a surprise visit to Belfast, both Prince William and fiancée Kate Middleton attempted the tricky pancake flip for a charity fundraiser to mark Shrove Tuesday - Pancake Day. William tossed his pancake with aplomb. After some practice Kate was tossing with ease.
One top fuel dragster 500 cubic inch Hemi engine (6,000 horsepower) makes more horsepower than the first 4 rows of stock cars at the Daytona 500.
Top fuel dragster vs. Z06 Corvette Imagine you are driving the Chevrolet Corvette Z06 twin-turbo 7.0-liter LS7 at 800 horsepower and $140,000. What if a top fuel dragster is staged and ready to launch down a quarter mile strip (440 yards)? You're doing 200, the dragster just starts the moment you pass him who will get to the ¼ mile finish line first? The dragster launches and starts after you. The dragster will pass you in under 4 seconds doing more than 300 mph. The acceleration of the dragster has put 8 times the force of gravity on the driver. Nothing on land accelerates faster on land. The dragster crosses the finish line first with room to spare. The dragster uses 1.1 gallons of nitro methane fuel per second as it goes down the track. Still, more than 80% of the fuel energy was lost to heat.
