Motion & Forces Vocabulary
Match the words to the correct definition.

a force of attraction between objects due to their masses
gravity a force of attraction between objects due to their masses

a change in speed (velocity) or direction
acceleration a change in speed (velocity) or direction

a force that opposes motion between two objects that are in contact
friction a force that opposes motion between two objects that are in contact

the tendency of an object to resistance a change in motion
inertia the tendency of an object to resistance a change in motion

a push or a pull (includes size and direction)
force a push or a pull (includes size and direction)

work the result of a force moving an object
(force and motion are same directio)

a measure of the amount of matter in an object
mass a measure of the amount of matter in an object

the rate of motion (distance ÷ time)
speed the rate of motion (distance ÷ time)

combination of all the forces acting on an object
net force combination of all the forces acting on an object

the speed of an object in a particular direction
velocity the speed of an object in a particular direction

an object’s change in position
motion an object’s change in position

the pull of gravity on an object
weight the pull of gravity on an object

newton the unit for force
