it is obvious that our winters are not like those in miami. We can have some very harsh weather and it is important to be prepared when driving from place to place in the ice and snow. To be safe, car maufacrures must consider the elements of friction. This is why many cars have for wheel drive: for better traction on the ice. A car going down the road would qualify as kinetic friction and since the ice has little friction so the nature of the ice must be balanced. Another way to prevent acciden
in cheerelading the amount of force the base exerts on the flyer determines the speed of the flyer going up in the air. The momentum must be great in order for the stunt to work. The change in momentum is equal to the impulse of the flyer therefore as the flyer rises she gains momentum and at the peak of the flyers distance it comes to a complete stop in accelleration before it continues its bath back toward the bases on the ground. That decrease in momentum to 0 is the first part of the flyers
As winter becomes a more relevant topic the closer we get to the holidays more and more physics can be found in our everyday lives. For example when enjoying a fun day in the snow something I like to do is throw snowballs. A snowball is a projectile that only has gravity and air resistance acting on it. In order to throw the snowball the fastest you must take into consideration Newtond's 2nd law of motion. F=ma which is the net force is equal to the mass times accelleration. This also means that
When I was a kid one of my favorite pass-times was the toy "Skip It" which consisted if a ball at the end of a rope with a ring on the other end. The ring went around your ankle and you spun it around to get it moving then as the bal came around you jumped over the rope with your other foot. The tension in the rope is what keeps the ball in its horizontal circular path. The ball wants to keep moving in a staright direction however the length of the rope wont allow it. This is the basis of horizo
In cheerleading a stunt that can be done is called a basket toss. This is where the bases join there hands together to create a flat surface in which the flyer will load in and place her feet on there hands. The bases will exert a great amount of force on to the girl in order to throw her as high as possible in the air. Due to Newton's third law of motion, it is proven that the flyer exerts the same amount of force on the bases hands in the opposite direction. This explains why throwing the girl
Cheerleading is a growing sport across the nation and although there is much contaversy on whether it should be titled as an actual sport, there is no doubt that a great deal of physics is involved within cheer. For example, a stunt known as a basket toss is where the bases throw the flyer into the air so at her highest point she can hit an aerobotic move before coming back down. To reach the highest point possible, the flyer pulls up throughout her entire body accellerating quicly while the bas
