Test 4 Flashcards
______ and Galileo contributed most to our understanding of motion
Newton
A change in the state of motion of an object is caused by a _____
force
______ is the study of motion without regard to forces
Kinematics
______ is the study of the relationships that exist between forces and the motion of objects
Dynamics
Electromagnetic forces are _____ than gravitational forces
stronger
______ is the property of an object, which causes it to resist all changes in its state of motion
Inertia
Unless acted upon by an ______ force, an object at rest or in a state of uniform motion will remain at rest or in uniform motion
external force
An object is ______ when an unbalanced force acts upon it
accelerated
a net force of one ______ gives a mass of 1 kg on acceleration of 1 m/s^2
Newton
Acceleration of an object varies directly with the applied force and inversely with the Mass of an object
Mass
______ is the measurement of the gravitational force acting upon it
weight
_______ depends upon the amount of matter in an object and is independent of the location of the object
mass
the ______ method of measuring mass is easier and more widely used than the inertial method
gravitational
________ is a force that opposes the motion of an object
friction
the force of friction depends upon the types of surfaces in contact and the ______ force
normal
