Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it, in the direction of the force. The greater the net force, the greater the acceleration, and if the net force is zero, the acceleration will be zero, though the object may still be moving at a constant speed. An object's mass also affects its acceleration, as greater mass means it takes more force to accelerate the object.

1. NEWTON’S SECOND LAW
The acceleration of an
object is directly related
to the net force applied
to the object.

2. NEWTON’S SECOND LAW
The more force that is
applied, the more the
object will accelerate.

3. NEWTON’S SECOND LAW
The object will accelerate
in the direction of the
net force.

4. NEWTON’S SECOND LAW
Net force of zero will equal
an acceleration of zero.
The object may still be
moving, it will not be
changing speed or
direction.

5. NEWTON’S SECOND LAW
The more mass (inertia) an
object has, the harder it is
to accelerate.
The less mass an object
has, the easier it is to
accelerate.

6. NEWTON’S SECOND LAW

7. NEWTON’S THIRD LAW
When one object exerts a force
on a second object, the
second object exerts an equal
and opposite force on
the first object

8. NEWTON’S THIRD LAW
“For every action,
there is an equal
and opposite reaction”
