Mass correct answersThe matter in the universe (atoms and Molecules) is characterized in terms of its
mass. This is measured in Kilograms in the International system of units (SI).
Density correct answersthe amount of mass that occupies a given volume of space.
Force correct answersan application of energy to anobject with the intent of changing its position
(mainly its acceleration).
Displacement of an object correct answersis simply the distance it travels.
Velocity of an object correct answersis the distance it travels in a unit of time, such as miles as miles per
hour or meters per second.
The equation for Velocity correct answersvelocity = distance/time
Velocity correct answersincludes speed and direction
Vector correct answersarrow pointing in the direction of motion, with its length proportional to its
magnitude.
the total distance travled is calculated usesing what therom correct answersPythagrean Theorem
Pythagorean Theorem correct answersa²+b²=c²
Accleration correct answerschange in its velocity in a given period of time
Acceleration equation correct answerschange in velocity/time required
, Newton's First Law correct answersan object at rest will stay at rest, an object that is moving will stay
moving unless disturbed by an un balenced force.
Newton's Second Law correct answersForce = mass x acceleration
Newton's Third Law correct answersFor every action there is an equal and opposite reaction
Mass is a property correct answersof an object that remains the same while its intacts, no matter where
its located.
Impulse equation correct answersJ=Ft
Torque correct answersa force that causes rotation
Energy correct answersthe energy of a system results from the forces acting in it and is considered its
ability to work.
Work correct answersthe energy required to do work (which are the same) is calculated as the product
force and distance traveled along the line of action of the force.
Potential energy correct answersan object is equal to the work that's required to lift it from its original
elevation.
potential energy equation correct answersPE=mgy
total energy correct answersis the sum of the kinetic energy and the potential energy, both of which are
measured in foot-pounds or newton meters.
Its important to remember what about energy? correct answersIt can be neither created not destroyed,
so it can only change from one form to another.
