3. Force
• Force is a push or a
pull on an object.

4. Net Force
Net force is the
total force on an
object.

5. Unbalanced Force
Balanced Force
• Unbalanced Force can cause an
object to move, stop moving, or
change direction.
• The balanced forces are the forces
in equal and opposite directions.

7. • Can you see the
unbalanced force here?

10. Inertia
•An object at rest will
stay at rest unless acted
upon by an outside force.
•Inertia is every objects
resistance to change its
motion.

17. Newton’s Second Law

18. • The acceleration of an object is directly
proportional to the net force acting on
the object and inversely proportional to
the object’s mass.

19. Force=mass x acceleration
F=m x a
• a = Force/ mass
• a = F/m

20. Equation for Newton
It’s the
same as the
force
equation!
•Newton=m x a.

21. Force and mass.

22. Luke! Use the
mass times
the
acceleration!

23. Force and Acceleration
• Mass=Force/Acceleration
• m=F/a
