Quick Answer: Can Two Objects Have The Same Momentum But Different Kinetic Energies?

Does momentum equal kinetic energy?

Some people think momentum and kinetic energy are the same.

They are both related to an object’s velocity (or speed) and mass, but momentum is a vector quantity that describes the amount of mass in motion.

Kinetic energy is a measure of an object’s energy from motion, and is a scalar..

What happens when two objects with the same momentum collide?

For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. That is, the momentum lost by object 1 is equal to the momentum gained by object 2.

Why is there a 1/2 in the kinetic energy formula?

the formula for kinetic energy is the integral of momentum (Force)(Speed), so when you take the integral you have to add the 1/2 to ensure that the equation is correct. … *From the force equation () we know that acceleration is equal to force divided by mass.

Does Momentum have direction?

Momentum is a derived quantity, calculated by multiplying the mass, m (a scalar quantity), times velocity, v (a vector quantity). This means that the momentum has a direction and that direction is always the same direction as the velocity of an object’s motion.

Can a tiny bullet have more momentum than a huge truck?

Momentum is not equal to the mass of an object divided by its velocity. The momentum of an object can change. Two objects with the same mass will always have the same momentum. … A tiny bullet can have more momentum than a huge truck.

Can two different objects have the same momentum?

Two objects of varying mass have the same momentum. The least massive of the two objects will have the greatest kinetic energy.

Can an object have the same kinetic energy at two different velocities?

Kinetic energy is a function of mass and velocity, so objects of different masses can have the same kinetic energy.

Can a lighter object have more momentum than a heavier one how?

Can a lighter object have more momentum than a heavier one? … A) No, because momentum is independent of the velocity of the object.

What happens to momentum if kinetic energy is doubled?

So, momentum is proportional to square root of kinetic energy. Thus, if kinetic energy is doubled, then momentum will become √2 times original momentum.

Which one of the following has the largest kinetic energy?

Given question: Which of the following bodies has the largest kinetic energy? As 24Mv² is the largest kinetic energy among others, ∴ body with mass 3M and speed 4v has the largest kinetic energy.

Is momentum always conserved?

Collisions. In collisions between two isolated objects Newton’s third law implies that momentum is always conserved. … In collisions between two isolated objects momentum is always conserved. Kinetic energy is only conserved in elastic collisions.

Is momentum conserved when a ball is dropped?

Linear momentum of a system remains conserved unless an external force acts on it. Since during free fall, a gravitational force acts on the body, it’s momentum will not remain conserved.

What happens when you double the mass?

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.

Which car has the most kinetic energy?

Answer: The first car has the most kinetic energy.

Why do objects with more mass not always have more momentum?

Its mass, for one thing. After all, mass measures the inertia of an object – how much the object resists accelerating. Certainly, more mass means more momentum – the momentum of an object is directly proportional to its mass. Twice the mass means twice the momentum.

Can an object have kinetic energy but no momentum?

No , if a object has zero momentum then it doesn’t have kinetic energy because kinetic energy is half of linear momentum. where KE is kinetic energy and M is mass and V is velocity of the object.

Is momentum directly proportional to kinetic energy?

Ans. In a constant object, momentum increases directly with speed whereas kinetic energy increases the square of the velocity due to energy momentum relation.

Does momentum change with direction?

Notice that momentum does not just depend on the object’s mass and speed. Velocity is speed in a particular direction, so the momentum of an object also depends on the direction of travel. This means that the momentum of an object can change if: the object speeds up or slows down.
