216 newtons law -8 + free body diagram-9

Newton’s first law=

law of inertia= object desire to be in constant state unless acted opon by an external force

the amount of inertia is proportional to ___

mass (how much matter contained in object)

the heavier an object is, the more ___ they have, aka it is harder to ___

inertia

move

quantity of motion=

momentum

momentum= the property that a moving object has due to its ___ and ___

mass

motion

Momentum (M)=

mass x velocity (m x v)

M1=M2 implies that

conservation of momentum, where the momentum in one moment would equal to the momentum of another time

When 2 system come into contact, the momentum of the 1st object gets ___ to the second, it does not ___

transffered

get loss

Newton’s 2nd law is the law of ___

momentum

2nd law/ law of momentum states that to ___, we need to apply ___ over ___

change momentum

force

period of time

change in momentum is produced by an ___, which is ___ over ___

impulse (Ns)

force over time (F x t)

why is newtons 2nd law reffered to as both law of Momentum and Law of Acceleration

impulse= Force over time= change in momentum

change in momentum= change in velocity (not mass)

so that Force is actually changing velocity with respect to time, which gets you acceleration

so the 2nd law states that force applied to system= mass times acceleration= change in momentum

Newtons 3rd law =

law of action and reaction

law of action and reaction states that

for every force applied to a body, the second body would apply a equal but opposite force on the first

a free body diagram is not a ___ but a ___

scaled drawing

problem solving strategy

Free body diagram =a graphic illustration used to visualize the__ and __ of applied forces 

direction

magnitude

forces that act in the ___ can be summed , aka ___

same plane

colinear

forces acting in horizontal and vertical planes can be summed tgt using ____

vector addition
