Law of conservation of momentum
states, the total momentum of an system remains constant if no external forces act on the system.
is the energy of a moving object.
is a stored form of energy available to do work.
occur when the total kinetic energy of a system remains constant.
Law of Conservation of Energy
states, energy cannot be created or destroyed but is converted from one form into another or the total amount of energy in the universe is constant.
is the amount of matter or substance inside an object.
Its value does not change with the strength of gravity. Identical objects on Earth and on the Moon have identical masses.
have magnitude and direction. Direction or changes in direction have an effect on vector quantities. Examples include displacement, velocity, acceleration, force, momentum and field strength.
