Drag is affected by the area and shape of the solid object, the speed and orientation of the object relative to the fluid, and various properties of the fluid such as its density and kinematic viscosity. In addition to an exploration of free fall, the motion of objects that encounter air resistance will also be analyzed. We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. Factors Affecting Resistance:The word Resistance is an important term in electrical terminology. The faster that the object is falling increases not only the frequency of impact but the force of impact which results in greater friction forces acting between the object and the air. how does the nature of material affect the air resistance acting on it? endobj Temperature can also affect the resistance of a material. Air resistance is a type of drag force that happens when an object moves through air. Test different sized parachutes to see how changes in the size of the parachute affect flight.

Therefore, resistance must be kept low to increase the value of current. The parachute slows the skydiver down because it causes air resistance, or drag force. %&'()*456789:CDEFGHIJSTUVWXYZcdefghijstuvwxyz Q.5. Many parameters go into determining the drag, but it is a single real force. Air resistance is determined by the shape and size an object has, and it's orientation with respect to air movement, relative the object. Q.3.

JFIF K K C If there's gravity, gravity can slow down or accelerate the object depending on direction. This project will examine the relationship between materials and air resistance. This ratio (Fnet/m) is sometimes called the gravitational field strength and is expressed as 9.8 N/kg (for a location upon Earth's surface). The weight of the paper plane also affects its flight, as gravity pulls it down toward Earth. The electrons in insulators, like rubber, however, are not free to move. Do different types of materials affect air resistance differently? Speed, shape and frontal cross-section. In between the conductor and the insulator, there are pure semiconductors, having very high resistance. As the skydiver falls slowly to the earth, these "push and pull" forces are nearly in balance. So, we are protected from electric shock when we use rubber and plastic materials." "@type": "Question", As an object falls, it picks up speed.
