... acceleration, displacement, and time. Velocity cannot change unless it is acted upon by a force, as described by Newton's first law. Momentum is directly related to the object's mass and velocity, and the total momentum of all objects in a closed system (one not affected by external forces) does not ...

... 14. Law of Conservation of Energy: Energy can neither be created nor destroyed. One form of energy can be converted into another form. 15. Collision: The interaction among bodies involving exchange of momentum is called a collision. 16. Elastic Collision: In elastic collision both momentum and kinet ...

... It is possible to produce a velocity time graph to describe the motion of an object. All velocity time graphs that you encounter in this course will be of objects that have constant acceleration. Scenario: The Bouncing Ball Lydia fires a ball vertically into the air from the ground. The ball reaches ...
