7.4 Two-dimensional collisions Example Practice with 2D collisions Practice with 2D collisions Practice with 2D collisions Practice with 2D collisions

7.2 Collisions In a collision: Two or more objects strike each other The total external force is either zero or negligible, and therefore momentum is conserved Collisions are categorized by what happens to the total kinetic energy of the system. Continue Reading

When Isaac Newton was formulating his famous laws of motion, he was not thinking in terms of position, velocity, and acceleration. Instead, he worked with what he called the “quantity of motion.” This was a particular quantity that by itself Continue Reading
