Cards Term A constant Definition Something that remains the same Term Acceleration Definition -change in velocity/ change in time -can be negative -can be change in speed, direction, or both -from gravity is always constant Term acceleration due to gravity Definition -9.8 Term Accuracy Definition -how closely a measurement agrees with the accepted value Term Action-Reaction Definition For every force that one object exerts on another, the second object exerts an equal and opposite force back on the first object Term Air Resistance Definition The opposing force air has on a moving object. When it’s equal to gravity, you have equilibrium. Term Cosin Definition Adjacent/Hypotenuse Term Displacement Definition Location. Defines the distance and direction between two points. Term Equilibrium Definition -when the net force on an object is zero -if something is moving at a constant velocity, then it is in equilibrium Term Equilibrium Definition -when the net force on an object is zero -if something is moving at a constant velocity, then it is in equilibrium Term Fnet=ma Definition -the net force of an object is equal to the mass of the object times the acceleration -the net force of an object is equal to the sum of the two forces -Newton's second law Term Force Definition Push or Pull (has a direction) Term Free body diagram Definition Diagram that shows all the forces acting on an object Term Force of Gravity Definition -constant downward force on every object Term Hang time Definition -amount of time in air Term Inertia Definition The tendency of an object to resist change in motion. Term Interaction Definition -when objects exert forces on each other Term Law of inertia Definition -things keep doing what they are doing unless acted upon by a net force -Newton's first law Term Newton Definition -unit of force -1N=1kg•m/s2 Term Precision Definition -the exactness of a measurement -for a measuring device, precision is equal to one half the smallest division Term Precision Definition -the exactness of a measurement -for a measuring device, precision is equal to one half the smallest division Term Range Definition -distance traveled in X direction Term Scalar Definition -measurement with a magnitude alone Term Significant Digits Definition -the number of valid digits in a number Term Sin Definition Opposite/hypotenuse Term Speed Definition -distance traveled/ change in time -measurement with a magnitude alone (scalar) -absolute value of velocity Term Tangent Definition Opposite/adjacent Term Terminal Velocity Definition -when the object has reached its maximum speed possible Term Vector Definition -has magnitude and direction Term Velocity Definition -change in displacement/change in time -rate at which speed changes -has magnitude and direction (vector)
