Force: is a push or a pull exerted by one body on another body; a vector quantity
Newton: SI unit of force/weight
Dyne: small unit of force
Gravitational: ____ force is the force of attraction between objects by virtue of their masses; responsible for weights of the bodies on earth and motion of the planets (fundamental)
Electromagnetic: ____ force is an attractive or repulsive force between charged bodies (fundamental)
StrongNuclear: ____ ____ force holds the constituents of the nucleus of an atom together (fundamental)
WeakNuclear: ____ ____ force plays a role in the radioactive decay of some nuclei (fundamental)
Contact: ____ forces from direct physical contact between two objects
NonContact: ____-____ forces does not involve direct physical contact
Mass: is the quantity of matter a body contains; scalar quantity
Weight: is the force on a body due to gravity; vector quantity
Kilogram: SI unit of mass
Dynamics: is a part of mechanics that deals with the causes of motion
Inertia: is the property of a body that tend to resist a change in its state of motion
First: Newton’s ____ law states that when an object at rest will remain at rest or when in motion will continue to move with constant velocity unless acted upon by an unbalanced force
Second: Newton’s ____ law states that when a net force acts on a body, it will be accelerated in the direction of the force
Momentum: is the product of mass and velocity; vector quantity with the same direction of velocity
Impulse: is the product of force and time during which it acts; vector quantity with the same direction of force
Third: Newton’s ____ law states when a body A exerts a force on body B, body B will exert an equal but oppositely directed force on body A; to every action, there is an equal but opposite reaction
Friction: refers to resistance to motion between two materials in contact
Static: ____ friction applies to cases where friction is sufficient to prevent relative motion between the surfaces; starting friction
Kinetic: ____ friction is present when there is relative motion between the surfaces in contact
Rolling: ____ friction occurs when one surface rotates as it moves over another without sliding nor slipping at the point or area of contact
Fluid: ____ friction or drag force refers to the forces that resist relative motion of an object through a fluid or a fluid through another fluid
Terminal: ____ velocity occurs when the object stops accelerating and falls with a constant velocity
Uniform: ____ Circular Motion is the motion of an object traveling along a circular path at a constant speed but with changing velocity
Centripetal: ____ force is needed for an object to move in circular motion; part of gravitation, a universal attraction
Acceleration: Law of ____ is also known as the second law of Newton
Interaction: Law of ____ is also known as the third law of Newton
Equal: the relation of between mass (m) and weight (W) is W ____ to mg; acceleration due to gravity (g)
Nonfundamental: examples of ____-____ forces are gravity, ordinary forces like pushes and pulls, friction
Principia: a book where the English physicist and mathematician wrote his ideas on forces and motion based on Galileo’s work
Inversely: Acceleration is ____ proportional to the mass of the body
Directly: Acceleration is ____ proportional to the force
Equal: Net force is ____ to mass times acceleration
Thrust: is the push produced by high velocity gases escaping trough the exhaust of the engine
Motion: is a change in position of an object with respect to time
Gravitation: is a natural phenomenon by which all things with energy are brought toward one another; force that is part of a universal attraction
Subatomic: ____ particles are particles much smaller than atoms
Macroscopic: ____ particles are much larger than atoms and molecules
Galileo: developed idea about motion contrary to Aristotelian theory. father of modern science/physics; his greatest contributions was his emphasis on experimentation, an important component of scientific method
Aristotle: one of the philosophers and observers of nature that considered the natural state of a body is to remain at rest and a force has to act on a body for it to move and to keep it moving
Impact: is a high force or shock over a short time period
Vector: ____ quantity is described by both magnitude and and direction
Scalar: ____ quantity is described by magnitude only
Netforce: ____ ____ is the sum of all forces acting on a object
ImpulseMomentum: ____-____ theorem equation states when a net force F acts on a body, the impulse of the net force is equal to the change in momentum of the body; alternative statement of the second law of Newton
Moment: is an expression involving the product of a distance and a physical quantity
IsaacNewton: ____ ____ formulated the laws of motion and universal gravitation
