i am confused on how to set up a problem involving initial and final momentum :yuck: . . . please help
Force is a quantitative measure of the interaction between two objects. It is defined as the product of mass and acceleration, and is measured in Newtons (N).
Speed is a measure of how fast an object is moving, while velocity is a measure of both speed and direction. In other words, velocity takes into account the direction of an object's motion, while speed does not.
Kinetic energy is the energy an object possesses due to its motion, while potential energy is the energy an object possesses due to its position or state. Kinetic energy can be converted into potential energy and vice versa.
The law of conservation of energy states that energy cannot be created or destroyed, but can only be converted from one form to another. This means that the total energy in a closed system remains constant.
Mass is a measure of the amount of matter an object contains, while weight is a measure of the force of gravity acting on an object. Mass is constant, while weight can change depending on the gravitational pull of a planet or other celestial body.
