Sir Isaac Newton & The
Three Laws of Motion
5th Grade
Sir Isaac Newton
• He was born in England on
December 25, 1643.
• He lived for 85 years.
• Isaac Newton was raised by his
grandmother.
Newton’s Education
• He attended Free Grammar School
• Then went on to Trinity College
Cambridge
• Newton received both a bachelors
and masters degree
Newton’s Ideas
• Newton had new ideas about
motion, which he called his three
laws of motion.
• He also had ideas about gravity,
the diffraction of light, and
forces.

The Three Laws of Motion
• Law #1: Law of Inertia
• Law #2: F = m x a
• Law #3: Action/Reaction
Law #1: Law of Inertia
• An object at rest will remain at rest
unless acted on by an unbalanced force.
•
An object in motion continues in motion
with the same speed and in the same
direction unless acted upon by an
unbalanced force.
– This law is often called "the law of inertia".
*Learn More*
Law #2: F = m x a
• Acceleration is produced when a
force acts on a mass.
• The greater the mass (of the
object being accelerated) the
greater the amount of force
needed (to accelerate the object).
*Learn More*
Law #2: F = m x a
• The Second Law gives us an exact
relationship between force, mass,
and acceleration. It can be
expressed as a mathematical
equation:
•F = m x a
– FORCE = MASS x ACCELERATION
Law #3: Action/Reaction
• For every action there is an equal
and opposite re-action.
