Will a larger bike always have more momentum than a smaller bike?
No.Momentum is a combination of weight and speed, so something lighter travelling faster can easily have the same momentum as something heavier travelling slower.So, if the bigger bike also is the heavier bike, and the bikes are always travelling at the same speed, then it will have more momentum.Otherwise, anything goes.
Which has a greater momentum a heavy truck at rest or a moving automobile?
The momentum of any object depends on its mass and its speed. If a car and a bike are both moving at the same speed, then the car has more momentum because it has more mass than the bike. If the car and the bike are moving at different speeds, then we need to know the speeds of each, in order to make any determination about their respective momenta.
How can a racing bicycle have the same linear momentum as a pickup truck?
Momentum = mass x velocity The bike has a much smaller mass, but if its velocity is great enough and the truck's is slow enough, the product can be the same. mass(bike) X Speed(bike) = mass(truck) X speed(truck) for an example, Speed(x)=0 and speed(x)=0 therefore, the two momentums are equal.
How do you start after an emergency stop on a bike?
After an emergency stop on a bike, you need to start on a low note and low speed. You will keep accelerating as you gain momentum.
Can a car stop faster then a motorcycle?
Assuming the car and the bike are both traveling at the same speed and both have new brakes. The bike will stop faster than the car due to less momentum. Car is heavier, harder to get going fast, harder to stop fast.
What is the momentum of a 45 kilogram bike going 7.6 meters per second?
Momentum = m V = 45 x 7.6 = 342 kg-m/sec
Why is harder to stop a bicycle than a truck if they have the same momentum?
The momentum p of an object of mass m and speed v isp = mvThe kinetic energy K of the same object isK = 1/2 mv^2 = p^2 / 2mLets say the truck has velocity V and mass M, and the bike has velocity v and mass m < M. If their momentum is the same, this meansmv = MVtherefore v is greater than V since m is less than M. v^2 is therefore MUCH greater than V^2,so the kinetic energy of the bike is much greater than the kinetic energy of the truck. This means that it takes more energy to stop the bike than it does to stop the truck.
How do you know how fast you are going on a bike?
you have a car match your speed, then you look at your speed guage :P
Why the speed of bike decrease on upper gear when bike going on slope?
Going uphill takes more power than going on the flat, so unless you can add more power, you have to trade some speed for power to be able to go uphill.
Why does a semi truck have more momentum than a bicycle?
A parked semi truck has no momentum. A moving bicycle does. If both the bike and the truck are moving at the same speed in the same direction, the truck will have more because it has more mass.
What is the momentum of a bike with a mass of 10 kg moving with a speed of 5 ms?
Momentum P = mass m x velocity v So P = 10 x 5 = 50 kg m s-1
Compute the momentum of a 50 kg bike and a 30 kg rider going 10 m s?
Momentum = (mass) times (velocity) = (50 + 30) (10) = 800 kilogram-meters per second.
