In a drag vs velocity graph, the relationship between drag and velocity is that as velocity increases, drag also increases. This means that the drag force acting on an object moving through a fluid (like air or water) becomes stronger as the object moves faster.

How does the rocket equation account for drag in the calculation of a rocket's trajectory?

The rocket equation does not directly account for drag in the calculation of a rocket's trajectory. Drag is typically considered separately in the analysis of a rocket's flight path, as it is a complex force influenced by factors such as air density, velocity, and the shape of the rocket. The rocket equation primarily focuses on the relationship between the mass of the rocket, the velocity of the exhaust gases, and the velocity of the rocket to determine its overall performance and capabilities.


What is the difference between drag and velocity in the context of physics?

In physics, drag is a force that opposes the motion of an object through a fluid, like air or water. It acts in the opposite direction of the object's velocity. Velocity, on the other hand, is the speed of an object in a specific direction. So, the main difference is that drag is a force that hinders motion, while velocity is the speed and direction of that motion.


Does the mass effect the velocity of an object in orbit?

No, the mass of an object does not affect its velocity in orbit. The velocity of an object in orbit is determined by the balance between the gravitational pull of the object it is orbiting and the centripetal force required to maintain that orbit. This relationship is described by the laws of physics and is independent of the object's mass.


What is the formula for aerodynamic drag?

The formula for aerodynamic drag is given by: drag force = 0.5 * drag coefficient * air density * velocity^2 * reference area. It represents the resistance encountered by an object moving through a fluid like air, with factors such as velocity, air density, drag coefficient, and reference area influencing the drag force.


How does aircraft drag increase with speed?

Drag increases by the square of velocity increase, for example, tripling speed increases drag by a factor of nine!

Relationship between coefficient lift and coefficient drag?

For cylinders coefficient of lift is approximately half of coefficient of drag while they are equal for Aerofoils.

How do you measure aerodynamic forces in a homemade wind tunnel?

you could use a spring behind your object, and calculate inline reaction force from deflection. it will be essential the wind speed is accurately measured force will represent wind velocity squared *drag coefficient , once calculated the drag coefficient can be used elsewhere, in acceleration calculations for instance. measuring forces versus wind speed should produce a exponential graph in the form f = v^2 as drag force is proportional to square of velocity if you translate the action into freefall , at terminal velocity the forces balance, down = mass * gravity acceleration ( newtons) up = velocity ^2 * drag coefficient (newtons)


What is Worthington's law?

Worthington's Law is the law which dictates that a person who makes more money than you is better than you, and therefore beyond criticism. This law reads "More Money = Better Than" and it's used to gauge the value of human worth.

What relationship is there between the shape of an object and drag that is created?

Drag is due to the concept of fluid drag due to viscosity. This drag force can be calculated from an extremely hard to solve differential equation, the Navier-Stokes equation. For a sphere the equation simplifies to drag force=6*pi*viscosity*radius of the sphere*velocity. For other shapes with less symmetry the navier-stokes equation is harder to simplify. For example- a cube traveling through the air no longer has laminar, streamline flow of air. This results in turbulence and drastically increases the drag force. Hope that helps.

What does drag mean?

Drag coefficient can be defined as the ratio of the drag on a body moving through air to the prioduct of the velocity and the surface area of the body.


What is the difference between free fall and terminal velocity?

The difference between free fall and terminal velocity i that free fall is when an object is falling or descending through the air with little air resistance or drag. Terminal Velocity, on the other hand is when the resistance of air and the force of gravity balance each other out causing the object to reach a constant velocity. .


What is relation between viscosity and teminal velocity?

Viscosity affects terminal velocity by influencing the resistance experienced by an object moving through a fluid. Higher viscosity fluids result in greater resistance, leading to lower terminal velocities for objects moving through them. This relationship is described by the drag force acting on the object, which is determined by both viscosity and the object's characteristics.
