🚀 NET FORCE SIMULATOR
Explore how forces combine when objects are pushed or pulled!
📚 Learning Index
1. What is Force?
A force is a push or a pull acting on an object. Force can change the speed, direction or shape of an object.
A person pushes a box away.
A person pulls an object towards them.
Unit of force: Newton (N)
When several forces act on an object, their combined effect is called the net force or resultant force.
2. Forces Acting in the Same Direction
When two or more forces act in the same direction, their magnitudes are added.
Person A pushes with 10 N.
Person B pushes with 15 N.
3. Forces Acting in Opposite Directions
When forces act in opposite directions, subtract the smaller force from the larger force.
Rightward force = 30 N
Leftward force = 20 N
If both forces are equal, the net force is zero. The forces are balanced.
4. Force Applied by One Person
One person applies a force of 20 N towards the right.
5. Force Applied by Two Persons
Two people push in the same direction. Their forces add together.
6. Force Applied by Three Persons
Three people push a box in the same direction.
7. Interactive Net Force Experiment Lab
Choose an object, number of persons, force magnitude and direction. Watch the object move according to the resultant force.
LEFT SIDE ← RIGHT SIDE →
For this experiment, the action direction is the direction in which the force acts on the object. The people are illustrated symbolically on opposite sides.

8. Student Assessment
Calculate the net force and choose the correct answer.
⭐ Remember
- Force is a push or a pull.
- Same direction forces are added.
- Opposite direction forces are subtracted.
- Equal and opposite forces produce zero net force.
- Net force is measured in Newtons (N).
- A non-zero net force changes the motion of an object.
