To see what factors may affect the experiment, it may be useful to look at the formula for potential energy. Therefore the only factors that can affect this experiment are the height of the ramp and the mass of the trolley. For this experiment I will be investigating if varying the Friction between the ramp and the trolleys wheels, and air resistance will also slightly affect the overall results. Controlled variable How it will be controlled Why it should be controlled The incline of the surface will be kept level.

While this gives the race car more grip around corners, it also reduces overall speed of the race car. This effect is enhanced in a race car where air increases in speed as pressure decreases on the bottom of the car which creates a larger downforce. In Aero , we learned that drag is parallel to the airflow and reduces the speed of a race car Aero , Post. The Bernoulli Effect states that the pressure of a fluid, in gaseous or liquid state, varies inversely with speed or velocity and a slower moving fluid will exert more pressure on and object than the same fluid moving slower Yager. The goal of car designers is to make the air passing under a car move faster than the air passing over the car. Large amounts of downforce are needed to keep light cars grounded at high speed and keep to cars from sliding around turns at high speeds.

Findings from the study include: 1 average annual precipitation was estimated at While not everyone can have such an opportunity, there are still places that ignore the rules of gravity. Gravity hills allow all types of objects to travel uphill. What are they? How do they work?
What is the effect of air resistance on the acceleration of falling objects? What is the acceleration with no air resistance? Q: on an ice rink , two skaters of equal mass grab hands and spin in a mutual circle once every 3.
