On:
Newton’s 1st, 2nd, and 3rd laws, Force, Inertia, Balanced/ unbalanced
forces, friction, Net force, Mass, Acceleration, Force diagrams
2. Newton’s 1st Law
Newton’s 1st Law states that an object in motion, stays in motion, and
an object at rest, stays at rest at same direction unless acted upon an
unbalanced force.
3. Newton’s 2nd Law
Newton’s 2nd Law states that the acceleration of an object as produced
by a net force is directly proportional to the magnitude of the net force,
in the same direction of the net force, and inversely proportional to the
mass of the object.
4. Newton’s Third Law
In every action, there is always an equal and opposite reaction.
5. Inertia
• Inertia does not have units because it does not have a physical
quantity.
6. Gravity
“What goes up, Must go down.”
Everything in the universe has it.
It depends on two things, the mass of any two objects, and the
distance between them.
7. force
The strength of a force can be measured. How strong the push or pull
is measured with a spring scale in units called newton.
8. Net Force
The net force is the vector sum of all the forces that act upon an object.
10. Balanced And Unbalanced Forces
Forces occur in pairs and they can either be balanced or unbalanced.
11. Mass
The mass of an object is a fundamental property; a numerical measure
of its inertia; a fundamental measure of the amount of matter in the
object.
12. Friction
Force that opposes the motion of an object when the object is in
contact with another object of surface.

• By the way, if you haven’t noticed, I have been using cubs colors.
