When you ride a bicycle at full speed, which has the greater momentum – you or the bike? Explain why you go over the handlebars if the bike is brought to an abrupt halt. You have more momentum, because you a the bike are travelling at the same speed, but you have much more mass.

## Which has a greater momentum a car or a bike moving at the same speed?

Because car has more mass than bike it has higher momentum which is denoted by formula mass*speed.

## When you ride a bicycle at full speed and the bike stops suddenly Why do you have to push hard on the handle bars to keep from flying forward?

Same as before, when the drastic decrease in speed occurs (going from full speed to stopping suddenly), your body still wants to go at full speed. But this time, you press hard in the handlebars. This action allows all the inertia to push against the handlebars instead of open air.

## Is riding a bike an example of momentum?

Riding a bicycle is possible because of angular momentum. The angular momentum of the wheels is a vector that remains constant unless the external torque is imbalanced. … This makes it possible to turn a bicycle: leaning causes an external torque due to gravity resulting in the bicycle turning around a vertical axis.

## Would a motorcycle going the same velocity have more or less momentum Why?

Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.

## Is speed of bike and car same?

There will be no difference at all. As speed is universal standard for every moving objects, doesn’t matter its a Car, Bike, Plane, Rocket, wind and etc etc. If a bike and a car started from the same point at the identical time and both are at the speed of 60 km/hr then both will move parallel.

## How can a bicycle and a car have the same momentum?

For a truck and a bike to have the same momentum, the mass of the vehicle times the velocity of the vehicle must be the same for both of them. Therefore, the lighter, less massive bike will have a much higher velocity than the truck.

## What causes the bicycle to stop moving?

When we apply a break, the bicycle undergoes a change in it’s motion due to friction which stops the bicycle. … The frictional force is the reason which stops the bicycle when brakes are applied.

## Why do gymnasts use floor mats that are very thick?

Q:Why do gymnasts use floor mats that are very thick SolutionStep 1 of 1Gymnasts use thick floor mats, because the more thicker the floor mat, the slower gymnast willhit the floor,reducing the impulse hence the impact. A thicker floor mat reduces impulse and it will help gymnasts to avoid injuries.

## What law is being applied when you’re riding a bike then suddenly you hit a large rock?

This is often called the law of inertia. The law of inertia is most commonly experienced when riding on the roadways. In fact, the tendency of moving objects to continue in motion is a common cause of a variety of transportation injuries – of both small and large magnitudes.

## When you ride a bicycle in what direction is the angular momentum of the wheels?

When you are riding a bike forward, the right hand rule gives the direction of angular momentum to be to the left, perpendicular to the wheel.

## Which has more momentum a moving bike or an anchored ship in the port explain?

Taking the formula for momentum to be p=mv this is the mass multiplied by the velocity. … The bicycle however has both mass and velocity and therefore has the larger momentum of the pair.

## How does the conservation of angular momentum affect the stability of a bike?

With angular momentum, the total momentum of an isolated system will be constant unless an external torque acts on the system. … So, as long as no external torque is present, the axle of the wheels will remain horizontal, and the entire bike as a result will remain vertical.

## What object would have the most momentum?

The momentum of an object varies directly with the speed of the object. Two objects of different mass are moving at the same speed; the more massive object will have the greatest momentum. A less massive object can never have more momentum than a more massive object.

## What is the relationship between momentum and velocity?

In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object’s mass and directly proportional to the object’s velocity.

## Which has more momentum if it moves twice as fast?

A moving car has momentum. If it moves twice as fast its momentum is twice as much. lighter car, the momentum of the heavier car is as much. … The recoil momentum of a gun that kicks is (more than) (less than) (the same as the momentum of the bullet it fires.
