What will be the momentum of a stone having mass of 10 kg?
20 kg m/s
Are heavier cars faster?
What’s clear is that a lighter car will accelerate more or require less force to accelerate like a heavier car. As the acceleration is slower with a heavier car of the same power, you have to accelerate for longer (more time) to cover the same distance so you use more fuel.
What car has the highest power to weight?
Top 50 Supercars listed by power to weight ratios
| No. | Make | Power to Weight (hp/lb) |
|---|---|---|
| 1 | Hennessey | 55.87 |
| 2 | McLaren | 51.97 |
| 3 | McLaren | 51.74 |
| 4 | SSC | 51.92 |
What is a good power to weight?
In the end, if we’re talking about horsepower, I don’t think there’s necessarily a limit. Maybe 5 pounds per horsepower if we really need to put a cap on it. But for torque, I think 10-15 pounds per ft-lb is a good range. That’s plenty to have fun (the average car is sitting at 18-20), but not enough to be scary.
Is it better to have a higher or lower power to weight ratio?
Power to weight ratio is the ratio between the power that your vehicle has and its weight. The higher the number, the better. For example if your car has 300HP and weights 1000 pounds, the power to weight ratio is 0.3 HP/pound, which means that your car outputs 0.3 HP for every pound it weighs.
Does more weight mean more power?
More weight may mean more power but it’s required to move the added weight at the same speed as a lighter guy with less power. A 250 hp car that weighs 2500 lbs will outrun a 350 hp car that weighs 4500 lbs. More power isn’t the answer, it’s the power to weight ratio.
What are the benefits of better power to weight ratio?
Since the engine has less to haul, it can focus more on speeding up. The same principle applies to athletes. By cutting on down the amount of weight they’re carrying, an athlete can increase his or her speed and endurance. The more power an athlete has per pound, the higher the power-to-weight ratio.
What is the benifit of more power to weight ratio?
But in terms of sheer acceleration ability and speed – the higher your power to weight ratio, the better. That means the ideal performance car is lighter in curb weight but jacked to the hilt in horsepower.
What is Torque to weight?
Definition: The ratio of torque to the weight of the moving part of an instrument is known as a torque/weight ratio. It indexes the performance of the instrument. The high value of the torque-weight ratio shows that even for the small value of deflecting torque, the pointer deflects and shows the measured value.
