Conceptual Physics 12th e. by Paul G. Hewitt Summary of Terms, Summary of Formulas, and Terms Within the Textbook
Terms in this set (10)
Impulse
The product of the force acting on an object and the time during which it acts.
Law of Conservation of Momentum
In the absence of an external force, the momentum of a system remains unchanged. Hence, the momentum before an event involving only internal forces is equal to the momentum after the event: *mv (before event) = mv (after event)
Elastic Collision
A collision in which colliding objects rebound without lasting deformation or the generation of heat.
Inelastic Collision
A collision in which the colliding objects become distorted, generate heat, and possibly stick together.
Momentum
The product of the mass of an object and its velocity.
Impulse-Momentum Relationship
Impulse is equal to the change in momentum of the object that the impulse acts upon. In symbolic notation:
Ft = ∆ mv
∆
A Greek letter often used to denote "change in" or "difference in".
Vector Quanitity
A quantity that has both magnitude and direction.
System
In physics, it may be as tiny as an atom or as large as the universe. We usually refer to it as a the relationship between two objects.
Conserved
The term applied to a physical quantity, such as momentum, energy, or electric charge, that remains unchanged during interactions.
