to stay at rest unless acted upon
by an unbalanced
-Also called as “Law of Inertia”

Lesson 3 – Newton’s Three Laws of Motion
Sample problem 3:
Suppose a ball of mass 0.60kg is hit
with a force of 12N. Its acceleration
will be:
If the force is increased to 24N for the
same ball. What would be its
acceleration?
