newtons laws
what is the first newton law?
objects will stay in motion and objects at rest will stay at rest unless acted upon an unbalanced force
whats a force?
a force is a push or pull on an object resulting from its interaction with another object
what are magnets
magnets are metals that are capable of generating forces of attraction and repulsion
whats potential energy?
potential energy is stored energy that results from the position or shape of an object
a car driving slow and then fast, what law is this?
newtons 2nd law
what is gravitational force?
an attractive force that acts between any two objects
what does S and N stand for on a magnet?
south and north
true or false potential and kinetic energy are the same?
false
kicking a soccer ball.
what law is this?
newtons first law
how many forces are acted upon a roller coaster?
2:gravitational force and normal force
if 2 south sides face each other what would happen?
they would push themselves away because they cant connect.
whats the difference between potential and kinetic energy?
potential energy is stored energy that results from the position or shape of an object and kinetic energy is energy in motion.
for every action, there is an equal and opposite reaction.
what law is this?
newtons 3rd law
what is net force?
net force is the sum of all forces acting on an object.
true or false, is copper magnetic?
No,copper is not magnetic
where would be the most kinetic energy be on the top or bottom of a hill?
bottom of a hill
how many laws act upon a swing set?
all 3 of them
how many forces are acted upon a rocket ship?
3: thrust,lift, and air resistance
how are magnets made?
by heating them to their Curie temperature or beyond?
where is the greatest amount of potential energy on a roller coaster?
where your about to go down the hill
