Advanced Physics Newton's Laws Vocabulary Set
Terms in this set (19)
A push or a pull.
The sum of all forces acting on an object
The tendency of an object to resist a change in motion
Newton's 1st law of motion
An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
Newton's 2nd law of motion
Force = mass x acceleration
Newton's 3rd law of motion
For every action force there is an equal and opposite reaction force
A diagram used to isolate a body from its environment, showing all external forces acting upon it.
A contact force that is perpendicular to the surface that an object contacts.
A measure of the gravitational force exerted on an object.
A measure of the amount of matter in an object
The vector sum of an object's real weight and the negative of all the forces that produce the object's acceleration.
Extension is directly proportional to force until the spring reaches it's elastic limit.
The pulling force transmitted axially by the means of a string, cable, chain, or similar one-dimensional continuous object.
A state in which opposing forces or influences are balanced.
A force that opposes motion between two surfaces that are in contact.
The force that opposes the movement of two surfaces that are in contact and are moving over each other.
Coefficient of kinetic friction
The ratio of kinetic friction to the normal force.
The force that resists the initiation of sliding motion between two surfaces that are in contact and at rest.
Coefficient of static friction
A dimensionless constant depending on the two surfaces in contact. It is used to calculate the maximum static frictional force that needs to be overcome before motion begins.
