Investigating Air Resistance We are trying to investigate the effect of air resistance to the speed of a trolley moving down a ramp in relation to the area of a sail attached to the trolley. The prediction I have made is that the larger the sail area, the longer the trolley will take to descend, i.e. it will be slower. The variable I will be changing is the height of the sail, and so, the area of the sail. Some variables cannot be changed, but may affect the result of the experiment

Satisfactory EssaysAir Resistance on a Fan Car Problem: When a large fan is blowing air against the fan car at three different speeds (high, medium, and low), then will the overall speed be lowered? Materials: · Fan car (K’NEX pieces, small, battery-powered fan, wheels with tires) · AA batteries · Large 3-speed fan · Timer · Masking tape Process: 1. Load two AA batteries into the fan that is attached to the K’NEX car. 2. Mark a starting line and a finish line two meters away from each other with

Satisfactory Essaysnarrow. This is so a minimum of air resistance or drag affects the dragster with lower drag better acceleration an in turn a better top speed can be achieved all leading to a better pass (race time). Now lets try to understand the concept of air resistance and drag. A basic example is placing your hand out the window with your palm facing forwards as you are driving your car along at about sixty kilometres per hour. You will feel a strong force of the wind (air resistance) pushing back at your hand.

Satisfactory EssaysEffect of Air Resistancehe on the Fall of a Certain Mass In this experiment I will be finding out how long it will take for a certain amount of mass to fall from a height of 58.5cm. The times will vary because I will be adding fans to create air resistance. Variables In this investigation I will have the following as variables: Å¸ The weight of the mass, so that the fans can be tested at different levels of acceleration; Å¸ The amount of fans, so that the amount of air resistance can

Satisfactory Essaysskiing so fun and challenging. I will also discuss how things like wax and the shape and width of your skis can affect these laws of physics and enhance your skiing. There are really only two main forces acting on a skier, they are gravity and air resistance. The first and most important thing relating to the physics of skiing is the law of gravity. Gravity is the most familiar force in our everyday lives it is the force that keeps us on the ground it is also the force that makes things fall. We have

Better EssaysGravitational Pull and Parachute Investigation Aim The aim of the experiment is to investigate how each of several different weights of varying mass attached to a parachute in turn can influence the gravitational pull and air resistance forces acting on it, consequently affecting the time it takes to reach the ground when dropped from a specific height. Preliminary Work Forces are measured in Newtons (N), named after Isaac Newton who invented this unit. We cannot see them but instead

Satisfactory Essaysfirst. This is due to air resistance, which is the force air exerts on a moving object. This force acts in the opposite direction to that of the object's motion. In the case of a falling object, air resistance pushes up as gravity pulls down, which causes the object to slow down. When Galileo's experiment was repeated on the moon, the hammer and the feather hit the ground at the exact same time. This is due to the fact that the moon has no atmosphere. Therefore, air resistance doesn't exist on the

Satisfactory Essaysm with M and define M as the instantaneous mass of the rocket, including the unexpended fuel. We also have to incorporate the other forces acting on the rocket, such as gravity and air resistance.� The force of gravity is equal to mg.� The force of air resistance is �where C is the drag coefficient, is the air density, A is the cross-sectional area of the body perpendicular to the velocity, and v is the velocity.� By themselves, these formulas seem somewhat easy, but a rocket�s flight incorporates

Satisfactory Essaysis air resistance. So to make air resistance the same size as the downward force, the object has to be travelling at a fast enough velocity. A heavier weight will accelerate to a higher terminal velocity before these two forces are balanced than a lighter one. This is because air resistance increases when velocity increases as more air particles collide with the object, which slows the acceleration of the object down. So the heavier the object the larger the downward force so more air resistance
