What will happen to weight of body if earth stops rotating?
The maximum weight will be a t equator. If the earth stops rotating then there would be no centrifugal force whose direction is away from the core. Thus the force due to gravity is not minimised at all and this in turn increases an object’s weight at the equator.
Does weight decrease as speed increases?
For all intents and purposes, your mass (and weight if you’re earthbound) does not change with speed. For all intents and purposes, your mass (and weight if you’re earthbound) does not change with speed.
Does Weight Affect car speed?
Weight affects speed down the ramp (the pull of gravity), but it’s the mass (and friction) that affects speed after a car leaves the ramp. Heavier cars have more momentum, so they travel further, given the same amount of friction.
How can I increase the top speed of my car?
Increasing aerodynamics: cover your wheel wells with air dams, tape over body panel gaps, cover some of your front grill area with tape (be sure sufficient air comes through for cooling), cover the underside of your car to smooth it out. Less drag = higher top speed.
What limits the top speed of a car?
A speed limiter is a governor used to limit the top speed of a vehicle. For some classes of vehicles and in some jurisdictions they are a statutory requirement, for some other vehicles the manufacturer provides a non-statutory system which may be fixed or programmable by the driver.
What is better hp or torque?
In physics, power is defined as the rate at which something does work. For cars, horsepower translates into speed. So if you want to go faster, and get up to speed quicker, you need more horsepower. Torque, on the other hand, is the expression of a rotational or twisting force.
What is the best aerodynamic shape?
For speeds lower than the speed of sound, the most aerodynamically efficient shape is the teardrop. The teardrop has a rounded nose that tapers as it moves backward, forming a narrow, yet rounded tail, which gradually brings the air around the object back together instead of creating eddy currents.
What is the most aerodynamic car ever built?
ARVW concept car
What is the lowest drag car on earth?
You may not think an entry-level luxury sedan could claim the title of the most aerodynamic car. But according to Mercedes, the new A-Class sedan features the lowest drag of any production vehicle in the world, with a coefficient of 0.22. At this level, it defends the world record held by the Mercedes-Benz CLA.
Does Shape Affect drag?
Geometry has a large effect on the amount of drag generated by an object. As with lift, the drag depends linearly on the size of the object moving through the air. The cross-sectional shape of an object determines the form drag created by the pressure variation around the object.
