Which vehicle has the most momentum?

The truck has more momentum than the car. By momentum, we mean inertia in motion. Momentum is the mass of an object multiplied by its velocity. A moving truck has more momentum than a car moving at the same speed because the truck has more mass.

Why does a fast moving car have more momentum?

Why does a fast moving car have more momentum than a slow-moving car of the same mass? Because faster objects have more momentum than slow objects. Some of all of the momentum from the first object is transferred to the second object.

Which has more momentum a small car moving at 30m S or a large truck moving at 30m S?

mass times its velocity. Which has more momentum, a large truck moving at 30 miles per hour or a small truck moving at 30 miles per hour? twice as much momentum. it is accelerating (or decelerating), there is a force acting on it, its velocity is changing.

Which cart has the greatest change in momentum?

Explain. Balloon B has the greatest momentum change. Since the final velocity is greatest for Balloon B, its velocity change is also the greatest.

Can a car have more momentum than a train?

During the collision, the speed of each car changes. The blue car slows down to 2 m/s, and the green car speeds up to 4 m/s. Momentum is conserved – the momentum of one train car decreases while the momentum of the other increases.

Which has more momentum a bullet or a car?

It is the bullet traveling at high velocity that does the damage. Multiply these two numbers together and you get a bullet momentum of about 3.2 kgm/s. In contrast, modern cars have a mass of about 1500 kg. Traveling at a highway speed of 25 m/s (55 mph), a car has a momentum of about 38,000 kgm/s.

Why is a moving vehicle difficult to stop?

Answer: Explanation: because it’s in inertia to move in simple language the speed and force is very high so when we are going to stop it we have to apply a lot of pressure to reduce the it’s speed to normal.

Why would it take more force to stop a fast moving car than a slow moving one?

Terms in this set (10) The truck has more mass thus, more momentum. So the truck needs a larger force to stop it. a fast moving car has a greater velocity and more momentum than a slow moving car of the same mass.

Which has the greater momentum when they move at the same speed?

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.

Why is momentum conserved but not energy?

Momentum is conserved, because the total momentum of both objects before and after the collision is the same. However, kinetic energy is not conserved. Some of the kinetic energy is converted into sound, heat, and deformation of the objects. In an elastic collision, both momentum and kinetic energy are conserved.

What happens when two objects with different mass collide?

In accord with Newton’s second law of motion, the acceleration of an object is dependent upon both force and mass. Thus, if the colliding objects have unequal mass, they will have unequal accelerations as a result of the contact force that results during the collision.

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.

Is momentum a change?

1) The change in momentum of an object is its mass times the change in its velocity. 2) The change in the momentum of an object can also be found by considering the force acting on it. If a force, F, acts on an object for a time, Δt, the change in the objects momentum is Δp=F⋅Δt.

What is the rate of change of momentum equal to?

Momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton’s second law of motion states that the time rate of change of momentum is equal to the force acting on the particle.
