Newtons Three Laws of Motion
Newton's laws of motion describe fundamental principles governing the behavior of objects. The first law states that an object will remain at rest or in uniform motion unless acted upon by an external force.

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