|
|
|
Units of Force
|
They are Newton (N) and the pound (lb)
|
|
|
Acceleration
|
A force which affect an objects motion
|
|
|
gravity
|
Gravity pulls all objects together
|
|
|
Friction
|
Friction is a force that that opposes the motion of one object moving past another
|
|
|

|
|
Lift
|
A push into the air
|
|
|
drag
|

|
|
|
Balanced force
|
Balanced forces is often point in opposite direction making it zero
|
|
|
Unbalanced force
|
A force that causes a object to change its motion
|
|
|
Newton’s first law
|
An object at rest to tends to stay at rest ,and an object in constant movement will continue unless act by a unbalanced force
|
|
|
Newton’s second law
|
The unbalanced force on an object is equal to the mass multiplied by its acceleration: F = m * a
|
|
|
Action force
|
The push on a first object to the second object
|
|
|
Reaction force
|
The push on the second object back on the first object
|
|
|
Newton’s third law
|
All forces occurs in pairs, and these two forces are equal in strength and opposite in direction
