Two objects with the same mass move with the same speed but in opposite directions. A. Kinetic energies are equal B. Kinetic energies are opposite in magnitude C. Kinetic energies of the higher objects is greater D. Kinetic energy of the lower object is greater

this is the best answer for you

When two objects collide there will be a force acting on them both and their individual kinetic energies and momenta may alter. As you know already, energy is always conserved but in a collision some, or all of the kinetic energy may be ... of the same mass and traveling at the same speed but in opposite directions collided ...

the closer the planet is to the sun, the larger the gravity
