How can two cars have equal and opposite momentum if travelling at differen speeds?
Two cars can have equal and opposite momentum if they have different masses. Momentum is the product of mass and velocity, so even if the two cars are traveling at different speeds, their momenta can be equal and opposite as long as their masses are inversely proportional to their velocities.
Is momentum conserved when two carts having the same mass and the same speed and stick together they stop?
Yes, momentum is conserved in this scenario. When the two carts stick together after colliding, their combined mass is still the same as the sum of their individual masses. Therefore, the total momentum before the collision is equal to the total momentum after the collision, leading to a total momentum of zero as the carts come to rest.
How do two kinetic energies compare with one another?
The kinetic energy of an object is directly proportional to its mass and the square of its velocity. When comparing two kinetic energies, the object with the greater mass or velocity will typically have a higher kinetic energy. Alternatively, if their masses and velocities are equal, then their kinetic energies will also be equal.
How can it be possible for two objects with different velocities to have the same momentum?
Two objects with different velocities can have the same momentum if one object has a greater mass and a lower velocity while the other object has a lower mass and a greater velocity. Because momentum is the product of mass and velocity, if the product of mass and velocity for each object is the same, their momenta will be equal.
Does the ratio of the distances equal to the ratio of the masses in each of the cases?
Yes, according to Newton's law of universal gravitation, the ratio of the distances between two masses is equal to the ratio of the masses. This relationship holds true for gravitational forces acting between any two objects.

Does the velocity of two different waves in the same medium be equal?
no it is not equal
If two spaceships have equal masses and one is stationary and one is moving What is their combined speed if they collide and stick together?
The new speed for the combined masses will be one-half the original velocity of the moving spaceship, since the momentum is applied to a mass twice as large.
If masses are equal where does their center of mass lie.?
If the masses are equal, the center of mass lies exactly in the middle between the two masses. This is because the center of mass is a point that balances the masses, and with equal masses, the balance point is at the midpoint.
How can it be possible for two objects with different velocities to have the same momentum?
Two objects with different velocities can have the same momentum if one object has a greater mass and a lower velocity while the other object has a lower mass and a greater velocity. Because momentum is the product of mass and velocity, if the product of mass and velocity for each object is the same, their momenta will be equal.
If two solids have the same masses and different volumes do they have different or equal densities?
different equal
What are the two sub atomic particles which have relativel equal masses?
Protons and neutrons have relatively equal masses. Electrons have a much smaller mass than the others.
If two objects have the same velocity do they have the same momentum?
No, because momentum depends on velocity and mass so they may have the same velocity but if they have different masses then they will have different momenta. (momenta is the plural form of momentum.)
Does the ratio of the distances equal to the ratio of the masses in each of the cases?
Yes, according to Newton's law of universal gravitation, the ratio of the distances between two masses is equal to the ratio of the masses. This relationship holds true for gravitational forces acting between any two objects.
When two masses collide with each other will they move with equal velocities?
Generally, no.
