# Explain Why The Momentum Of A Large Tractor Trailer Is Greater Than The Momentum?

## Which has more momentum a large truck moving?

A moving truck has more momentum than a car moving at the same speed because the truck has more mass. A fast car can have more momentum than a slow truck.

## Which has a greater momentum a heavy truck or a moving automobile?

Terms in this set (20) Which has a greater momentum, a heavy truck at rest or a moving automobile? The truck at rest has no speed, hence no momentum. So the moving automobile has greater momentum.

## Why does a truck usually have greater momentum than a motorcycle?

The motorcycle will accelerate at a greater rate because the truck has a greater mass ( greater resistance to a change in speed.) In terms of momentum, a mass that experiences a change in velocity (acceleration) has undergone a change in momentum (impulse).

## Which has greater momentum a semi truck at rest or a bicycle in motion?

Explanation: Taking the formula for momentum to be p=mv this is the mass multiplied by the velocity. Although the semi truck certainly has a larger mass, it is not in motion and therefore does not have any momentum. The bicycle however has both mass and velocity and therefore has the larger momentum of the pair.

## What factors affect an object’s momentum?

What two factors affect an object’s momentum? Momentum is affected by the mass of the object and its velocity (or speed ).

## What is the momentum change of an object equal to?

The momentum change of an object is the mass•velocity change. The impulse equals the momentum change.

## When you say momentum is conserved we mean that?

Question: When We Say That Momentum Is “conserved,” We Mean The Momentum Of An Object Is The Same Before And After A Collision. The Momentum Of The Universe Increases; It Never Decreases.

## What happens when two objects with the same mass collide?

When two objects with the same mass collide, Newton’s laws tell us that they will accelerate the same amount but in opposite directions. Recall that force, velocity, and acceleration have both magnitude and direction. We use positive and negative signs to indicate the direction of each of these quantities.

## How is momentum conserved when two trailer trucks collide?

Answer. When a collision occurs in an isolated system, the total momentum of the system of objects is conserved. Provided that there are no net external forces acting upon the objects, the momentum of all objects before the collision equals the momentum of all objects after the collision.

## Can momentum be lost as heat?

If the net force acting on an object is zero, then the linear momentum is constant. In an elastic collision (such as a superball hitting and rebounding from the ground), no kinetic energy is lost. In an inelastic collision, some of the energy will be lost to heat or sound or light or some other energy.

## Can a truck have the same momentum as a lightweight bike?

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.

## Which has a greater momentum a truck with a mass of 2250 kg?

Which has a greater momentum —a truck with a mass of 2250 kg moving at a speed of 25 m/s or a car with a mass of 1210 kg moving at a speed of 51 m/s? The car has a greater momentum.

## Does a car have more momentum than a bicycle?

From this equation you can see that both the velocity of the object and the mass have an equal impact on the amount of momentum. By the same token, if a car and bicycle are traveling down the street at the same velocity, the car will have more momentum.

## When you ride a bicycle at full speed which has greater momentum?

You have more momentum, because you a the bike are travelling at the same speed, but you have much more mass. You therefore have more inertia, and require much more force than the bike to come to a stop. 4.

## What is a change in momentum called?

This change in momentum is called impulse, and it describes the quantity that we just saw: the force times the time interval it acts over. The greater the impulse, the greater the change in momentum.
