Essential Question: How do interacting forces affect the
direction of an object's motion?
The unit of measurement for force is the
Newton (N)
The formula for calculating force is:
Force = mass x acceleration

Essential Question: How do interacting forces affect the
direction of an object's motion?
Net Force
The total force acting on an object
Net Force = 0 it is a balanced force, the
object is staying still or is in constant
motion
If the net force is not zero, it is an
unbalanced force and the object’s motion
will change.

Essential Question: How do interacting forces affect the
direction of an object's motion?
Calculating Net force
It is the difference between the 2
forces; the object will move in the
direction of the stronger force
Net Force = 50 N
150 N
100 N

Essential Question: How do interacting forces affect the
direction of an object's motion?
When two or more forces act on an
object in the same direction, the net
force is determined by calculating the
sum of the forces. The object’s
velocity will increase in the direction of
the net force
