Why is the drag force in a car greater when the car is going fast?

The tires are spinning faster and creating more friction, also, You're heading into the air faster, even if the car is aerodynamic it still causes drag.

What force stops a parachute from falling too fast?
drag
Why do space vecitcles heat up as they enter the atmosphere?
They are going so fast that the force of the drag from the molecules in the atmosphere is so great that the friction heats up the shell of the spacecraft
How fast can a helicopter fly sideways?
quite fast, there is more drag from the fuselage going side ways and it would be less stable
Why does a planet close to the sun to revolve very fast?
Because of the stronger gravitational force from the Sun, you need greater "centrifugal force" to stay in orbit and thus a greater velocity.
Why is it called a Drag Strip?
A drag strip is called as such because it is a prepped straight track where vehicles "drag" race by accelerating as fast as possible in a straight line for a short distance. The term "drag" refers to the act of pulling or dragging something forward with force, which is what the vehicles do on the strip.
When water skiing if the boat was going fast would it create more drag or less drag for the skier?
The drag vs Speed graph will be a curve, with it's minimum at some speed greater than zero. At slow speed, the skier needs to angle the sji at a high angle to the water in order to produce enough lift to stay upright. This is known in Aerodynamics (and, I imaging, Hydrodynamics) as Induced drag. As the speed incearses, the skier can angle the ski at a lesser angle, thus reducing drag. However, as speed increases further, the frictional and drag forces associated both with the movement of the ski on the water, and the skier through the air increase ("Form and Parrasite" drag). The sum of all drag will reach a minimum where induced drag has reduced, but the other types of drag have yet to significantly increase. Drag will be greater at EITHER a slower OR faster speed than this minimum figure.
What causes the effect of microgravity when the space shuttle is orbiting the earth?
Centrifugal force.The orbiter is going so fast that the force created by going around the earth offsets the force gravity.
How does the shape of a car make it faster?
the shape of the car is vital when designing because if you want a high speed car then it has to be aerodynamic this makes it easier for the air to go around the car and stops it from having drag drag is the force of the air that is pushing on a car if you want a fast car you need less drag
What is the number of newtons is the gravitational force minus the number of newtons for the drag in water?
That depends how fast the object moves. However, once it falls in the water at a constant velocity, you know that the net force - which is just what the question is after - is zero.
How fast is a car going that it takes 131 feet for it to stop?
It depends on the decelerating force applied by the brakes.
How fast must a car with 51ft of surface area travel in order to experience a drag force of 430 N?
You need dome type of Formula to calculate this. The formula must relate drag and surface area. Assuming the surface area is at the face of the car, or not.
Is it true that the thing that affects how fast it falls is the objects surface area?
Surface area is ONE thing that can affect how fast an object falls. Two forces determine how fast an object falls - the force of gravity and the opposing drag on the object from the medium it is falling through. In the case of an object falling in a vacuum, there is no drag so the object falls strictly according to the law of gravity. If an object is dropped through a fluid such as air or water, it can reach a terminal velocity where the force of gravity is exactly counterbalanced by the opposing drag on the object. In this case acceleration ceases - although motion does not. In other words, the object continues to fall, but it doesn't speed up. Drag force is a function of object velocity, viscosity of the fluid it is falling through, the surface area of the falling object, the surface roughness of the falling object, and the geometry of the falling object (spheres usually have less drag than cubes for example).
