Air resistance can be lowered by designing your "box" so that it slips through the air it is parting as it goes by. Just because it looks cool and fast that may not be the case. The back spoilers do no good at normal road speeds.
No, the work done in moving a body does not depend on how fast or slow the body is moving. The work done is determined by the force applied and the distance over which the force is applied, not the speed of the body.
No, it is not possible to stop a fast-moving automobile instantaneously. This is because it takes time for the brakes to apply force and for the vehicle's momentum to be reduced to zero. Additionally, the sudden stop could lead to skidding, loss of control, or damage to the vehicle.
A fast-moving stream is called a river or a torrent.
Air moving very fast is typically referred to as "wind."
A lorry travelling fast would experience more air resistance due to its high speed and larger surface area compared to a streamlined car travelling slowly. The faster an object moves through the air, the greater the resistance it encounters.
It's a marketing image that symbolises speed. The jaguar is a fast animal, with a streamlined body. The car of the same name is designed to be streamlined, and is a fast vehicle.
To run fast through thick vegetation.
I think why they can run fast is something to do with their feathers.
because they are thin and and travel smoothly
Yes. If a fast moving body has an impact with another fast moving body, the velocity of that initial body will be transferred into the latter body.
to escape from its predator so it need to swim very fast to escape from them or to swim fast to catch preys :-)
speedometer
Falcons fly at fast speeds, because their body is streamlined which lets them cut through the air easily.
It is moving at a maximum legal speed of 25 mph. However, it could be going slower. Legally, even if the vehicle can exceed 25 mph, it is not supposed to.
aircrafts and fast cars are streamlined so that the air flows over them more easily
gravity (:
The speedometer shows how fast a vehicle is travelling. It begins with the letter s.
