Force and Motion Vocab

Force

• The strength of an object or event

• A push or a pull

• The rate at which an object's speed and/or directions changes over time

• Energy in motion

Newton

• A measurement of force

• The total amount of matter in something

• A push or a pull

• The tendency of an object to resist a change in motion

Friction

• A measurement of force

• The tendency of an object to resist a change in motion

• The force between objects that affects how easily they move past each other

• A force that pulls objects together

Air Resistance/Drag

• The strength of an object or event

• The net force of an object does not equal zero which results in a change in the motion of the object

• The force between objects that affects how easily they move past each other

• The force of air pushing against a moving object

Magnitude

• The strength of an object or event

• A push or a pull

• The rate at which an object’s speed and/or directions changes over time

• A force that pulls objects together

Net Force

• The strength of an object or event

• The sum of all the forces acting on an object

• A force that pulls objects together

• Energy at rest or stored energy

Balanced Force

• The sum of all the forces acting on an object

• The net force of an object does not equal zero which results in a change in the motion of the object

• The net force on an object is zero and the object’s motion does not change

• The force between objects that affects how easily they move past each other

Unbalanced Force

• The sum of all the forces acting on an object

• The force between objects that affects how easily they move past each other

• The net force on an object is zero and the object’s motion does not change

• The net force of an object does not equal zero which results in a change in the motion of the object

Acceleration

• The tendency of an object to resist a change in motion

• The rate at which an object’s speed and/or directions changes over time

• The distance traveled by an object in a given amount of time

• Speed + Direction

Speed

• The tendency of an object to resist a change in motion

• The rate at which an object’s speed and/or directions changes over time

• The distance traveled by an object in a given amount of time

• Energy in motion
