What happens to the momentum of an object when it strikes another object? Scholars roll a marble down a ramp so it collides with another marble. By measuring the speed of each marble before and after the collision, pupils answer this...

Be impulsive with your high school physics class. Emerging physicists review the slide presentation and learn about impulse, momentum, collisions, and how each variable may be affected. They complete practice problems and conclude with a...

By the end of this section, you will be able to describe an elastic collision of two objects in one dimension, define internal kinetic energy, derive an expression for conservation of internal kinetic energy in a one-dimensional...

By the end of this section, you will be able to discuss two-dimensional collisions as an extension of one-dimensional analysis, define point masses, derive an expression for conservation of momentum along the x-axis and y-axis, describe...
