Forces

Front 1

What is a force?

Back 1

A "Push or Pull" vector quantity with unit N (newtons)

-Can produce or cause a change in motion

Front 2

If one force acts on an object, it ______ exhibit change

Back 2

will

Front 3

Two or more forces ____ exhibit change (unbalanced forces), but they can also ________ each other

Back 3

can, cancel (or balance)

Front 4

Multiple forces applied on an object >>>>>>

Back 4

Object feels an overall force

Front 5

Sum of all forces applied on an object:

Back 5

Net force

Front 6

Mechanical Equilibrium

Back 6

System has no net force

Does not necessarily mean no motion.

EF=0 F= vector forces

Front 7

Newtons First Law of Motion

Back 7

Objects at rest stay at rest. Objects in motion stay in motion, and continue in motion at a constant velocity unless acted upon by an outside force.

Front 8

Newton's Second Law of Motion

Back 8

The amount of acceleration that the net force produces depends on the mass of the object being accelerated.

EF=ma

Front 9

Mass

Back 9

amount of matter an object contains.

Front 10

Weight

Back 10

force of gravity acting on an object

Front 11

Friction

Back 11

Force dependent on direction of motion.

Resistance to motion that occurs between two materials that are in contact with each other.

Front 12

Static Friction

Back 12

Frictional force preventing stationary items from moving.

Front 13

Kinetic Friction

Back 13

Frictional force resisting moving items from moving.

Front 14

Static friction is __________ than kinetic friction

Back 14

LARGER

Front 15

Newtons Third Law of Motion

Back 15

Whenever one object exerts a force on a second object, the second object always exerts an equal and opposite force on the first object.
