Property of an object to remain in its state of motion
What is inertia
When an unbalanced force acts on an object, the object will accelerate in that direction
What is Newton's Second Law of Motion
A diagram that shows all forces acting on an object
What is a free-body diagram?
Microscopic contact points adhere to one another
What is the cause of friction?
Formula corresponding to Newton's second law of motion (the force law)
What is Fnet = ma
What happens to inertia as mass increases?
Increases
An object remains in the same state of motion unless acted on by an outside force
What is Newton's First Law of Motion?
Represents the force due to gravity
What is Fg
Point right before which the object begins to move
What is Ffs max?
Standard unit for force in terms of fundamental units
What is kg m/s^2
Gravitational, electromagnetic, strong nuclear, and weak nuclear are all types of what?
Forces
The force that A exerts on B is equal and opposite to the force that B exerts on A
What is Newton's Third Law of Motion?
A type of applied force that has to do with ropes, strings, and cables
What is the force of tension?
Force resisting motion when surfaces are sliding relative to each other
What is kinetic friction?
What is the relationship between the coefficient of friction and the normal force?
Indirect relationship
An object that has acceleration and force in a certain direction has what?
Unbalanced forces
Which one of Newton's laws deals with inertia?
What is Newton's First Law of Motion
Always drawn perpendicular to a surface
What is the normal force?
Measure of the relative roughness between two surfaces
What is the coefficient of friction?
Formula to find the perpendicular component of the force due to gravity
What is Fg cos theta
How is gravitational field strength represented?
the letter "g"
Which object exerts more force on the other when a hammer strikes a nail?
They exert the same amount of force
Always acts in the opposite direction of motion
What is the force of friction?
Value that varies with the applied force up to a certain maximum point
What is static friction?
What unit does the coefficient of friction use?
No unit
