Newtons Three Laws of Motion
Newtons 1st Law of Motion
An object at rest remains at rest,
and an object in motion remains in
motion unless acted on by an unbalanced
force.
Pencil at rest on a table.
Golf ball on a tee.
Newtons 2nd Law of Motion
The acceleration of an object depends
on the mass and force applied.
Two different mass balls at
the same speed with the
same amount of motion move at
a different speed, or rate
A ice skater pushes against the
ice it accelerates faster in a
certain direction.
Newtons 3rd Law of Motion
Whenever one object exerts a force on a
second object, the second object exerts an
equal and opposite force on the first object.
When you sit in a chair you
exert a force on the chair,
and the chair exerts an equal
and opposite force.
A fireman turns on the hose
and is knocked backward.
