What is the term for tendency of an object to resist change in its motion?
Inertia
Explain the difference between balanced and unbalanced force.
balanced - 0N net force
unbalanced - net force does not equal 0
H2O + O2 -------> H2 + O3
what are the products and reactants?
reactants = H2O and O2
products = H2 and O3
= m x a
force
N
Force
Force that acts between two masses
gravity
If Eric exerts a force of 10N on a tree and Brandon exerts the same force on the same tree, in the same direction - what's the net force acting on the tree?
20N
What is the explanation for the idea the mass of products, has to be the same to the mass of reactants and vice versa.
The Law of Conservation of Mass
power
calories
energy
The acceleration of an object is equal to the
net force acting on it divided by the objects
mass
newtons second law
when an object exerts a force on a
second object, that object exerts an equal
and opposite force on the first object
newtons 3rd law
Motion of a falling object after given an initial forward velocity
projectile motion
