There's really no telling, as both bikes and cars can be used in such different conditions. In congested city traffic a dedicated bike rider can easily be as fast or even faster than a car, while on the open road a car can easily be 3-4 times faster than even a race rider.
12mph is the same whether you are riding a dirt bike, a bicycle, driving a car, or running. 12mph is also about 3mph slower than a fit person running.
Yes. The Formula for momentum is Momentum= Mass x Velocity. If the slower car has a larger mass, it will likely have a larger momentum.
A car has more kinetic energy than a bike because it has a greater mass and generally moves at higher speeds. Kinetic energy is dependent on both an object's mass and its velocity, so the larger, faster-moving car will have more kinetic energy compared to a smaller, slower-moving bike.
Momentum is calculated as the product of mass and velocity. Since a car typically has a much greater mass than a bike, even when both are moving at the same speed, the car will have greater momentum. Therefore, the car has greater momentum.
Speed doesn't make a big difference. Safety should be the priority In bike there is less safety then car. Obviously car is faster than motor bike.
These days car or bike is about $150
Yes, it is generally safe to use a car tire pump on a bike, but be cautious not to overinflate the bike tire as car tire pumps can deliver higher pressure than needed for a bike tire.
The kinetic energy of a moving object is proportional to the square of its velocity. Therefore, the car that is 4 times faster than the slower car will have 16 times the kinetic energy compared to the slower car.
Depends on what you think "a lot" is. A bike will need more space than a person but less than a car. Just take a look at a parked bike someplace and you'll see roughly how much.
Because bike riding beats walking, and bikes are much cheaper than cars, and most Chinese haven't got the money for a car.
The faster car travels at an average speed of 48 miles per hour, while the slower car travels at 36 miles per hour. To find the difference in their speeds, subtract the slower car's speed from the faster car's speed: 48 - 36 = 12 miles per hour. Therefore, the faster car travels 12 miles per hour more than the slower car.
Certainly, every solid object does. A bike will need more space than a person but less than a car. Just take a look at a parked bike someplace and you'll see roughly how much.
