Does size affect speed?
where t is the time taken.
Whatever be the size of two objects; if they have the same speed, they will cover the same distance in a given time.
But, usually objects with a better aerodynamic design will move faster (i.e.
have a greater speed) than a similar object with a poor aerodynamic design..
Do large balls roll faster than small balls?
Because of its greater rotational inertia, the larger ball has a greater rotational kinetic energy 0.5 Iω2, and hence a smaller translational kinetic energy 0.5mv2. This means that the larger ball has a smaller speed. A smaller ball has less surface area.
Does a smaller pulley spin faster?
Pulleys of Different or Same Size If a smaller pulley turns a larger one, the larger one will turn slower, but with more power available at the shaft. If a bigger pulley turns a smaller one, the smaller one will turn much faster than the bigger one but with less power available at the shaft.
Do lighter wheels increase horsepower?
A light aluminum wheel not only makes a street car hard to drive, it usually hurts at the track. … We would gain about 0.25 horsepower-seconds, or 0.02 horsepower average power gain over the track length with a 13 second car. Crankshaft. A crankshaft is a bit worse than a drive shaft.
Is AWD good for rain?
All-wheel-drive vehicles sense wheel slip and adapt to wet weather very well. AWD is better than FWD in the rain. You will notice the difference right away. Remember this:AWD helps keep your car stable on wet pavement.
How many pounds does 1 HP move?
550 poundsMost engines use horsepower to describe how much work they can do in a given amount of time. The constant 1 horsepower equals 550 foot-pounds per second. In other words, 1 horsepower is the amount of work required to move a load of 550 pounds over 1 foot, in 1 second.
Does Weight Affect horsepower?
Horsepower has nothing at all to do with the car’s weight. It is a measure of the maximum power that the car’s engine can produce. … All things being equal, a car with fewer pounds for each horsepower will out accelerate one with more pounds per HP.
Do lighter wheels improve ride quality?
Lighter wheels shouldn’t have much impact on ride quality. I suppose a heavier wheel dampens bumps some, but that’s mostly a guess. I wouldn’t worry about it.
Do lighter cars handle better?
Short answer: More weight means your car will have more inertia, and will take longer to change direction. This means that a heavier car generally takes longer to slow down when braking and for its direction to change once you start turning. A light car generally handles better than a heavy car.
Is it better to have more torque than horsepower?
Horsepower is how rapidly the vehicle can perform that work. … Of course, horsepower is tied to torque mathematically. Horsepower equals torque multiplied by rpm, divided by a constant. Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms.
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.
Will lighter wheels make my car faster?
Lighter wheels help your suspension rebound faster and reduce the inertia of the wheels. … When a wheel is spinning, its inertia to left to right movement is increased by the velocity of the wheel. Lighter wheels will because of that have much less inertia and turn in better and rebound faster.
Do lighter cars hydroplane more?
Vehicle weight – the lighter the vehicle the greater the tendency to hydroplane. Road surface type – non-grooved asphalt is more hydroplane prone than ribbed or grooved concrete.
Which pulley will turn faster?
Pulleys and Speed Alternatively, a larger pulley turning a smaller pulley results in the smaller one turning faster but with less shaft power. For example, a truck in high gear would have a more slowly turning engine but fast turning wheels, resulting in greater speed of the truck.
Why are lighter wheels better?
Lighter wheels can go faster because there is less weight to control. They’ll help you speed up your acceleration while decreasing the time it takes you to come to a full stop. They can also contribute to greater fuel efficiency because lighter vehicles use less fuel.
Does AWD prevent hydroplaning?
Yes, AWD vehicles can have tires hydroplaning in the front/ rear, but the other wheels that are driven can typically power you through, versus a FWD/ RWD vehicle can have both driven wheels making contact with the water and causing the car to lose control due to having no other driven wheels to power the vehicle out.
Is 300 hp enough?
300 horsepower is indeed a lot. Of course it all depends on how heavy of a vehicle you are driving. But for an average car, 300 is quite a good amount of power. … With a curb weight of 3494 lbs, the car had a top speed of about 120 mph.
