contact forces & motion Flashcards
does mass change
not usually
can weight change
yes if the force of gravity changed
if two objects have the same mass which one will have the greatest change in speed
the object acted on by a greater force
unbalanced force causes
causes objects to slow down, speed up, or change direction
balanced force
a force that is equal in strength buy opposite in direction
Newtons 1st law
Intertia- The property it matter to want to not move when resting or keep moving while in motion
newtons second law
A=F/M
To move an object of mass(M) you will need a force (F)
if mass increases what force do you need to move it
force needs to increase
newtons third law
for every action there is an equal and opposite reaction
if an object is traveling at a constant velocity which two forces will be equal
applied and frictional force
what unit is weight measured in
Newtons(N)
force
any push or pull on an object
What is a newton equal to
kg•m/sec/sec (kg•m/s^2)
sum of all forces
net force
displacement
distance and direction of an objects change in position from a starting point
