Newton's three laws of motion describe fundamental principles about how objects move and interact. The first law, often called the law of inertia, states that an object at rest stays at rest, and an object in motion continues in motion unless acted upon by an unbalanced force.
EX: A soccer ball won't move until the player kicks it.
A seat belt stops you from flying through the
windsheild it you hit the brakes to hard.
An object in rest remains in rest
and an object in motion remains in
motion unless and unbalanced
object acts
3rd Law
EX: If air is let out of a balloon quickly,
air pushes down & balloon goes up.
A fireman turns on his hose & is
knocked backwards.
For every action there is an
equal and opposite reaction
2nd Law
EX: You have to push a heavy ball harder
to get it to move as fast as a small one.
Push a large box & a small box with the
same force, the small box will go faster
The acceleration of an object depends
on the mass of the object and the
amount of force applied
