Today’s Lesson:
Combining Forces
Net Force is the combination of all forces acting upon a body.
When forces act together in the same direction, they are added.
When forces act in opposite direction, the are subtracted.
Vectors are used as a way to identify the direction and magnitude (strength) of the net force.
example
use vectors to determine the net force on a car with an applied force of 1500 N acting to the right moving it forward and a friction force of 2000 N acting to the left.
Also, assign forces a sign (+/-) based on their direction (just like a coordinate system)
+for right and up
- for left and down
Example
use vectors to determine the net force on a model rocket with an applied force of 1000 N acting upward and a friction force of 250 N acting downward.
