Force Diagrams
Read force arrows and work out which way something will move.
Force Diagrams shows objects with arrows pointing in different directions, and the child works out what those arrows mean. Level 1 asks whether the forces are balanced or unbalanced and which way an object at rest will move. Level 2 names the forces, such as gravity, the normal force, friction and an applied push.
After that, the game adds numbers. Students combine arrows to find the net force, then use mass and acceleration with newtons, kilograms and meters per second squared. Upper levels explore action and reaction pairs and split motion into horizontal and vertical parts for objects like a drone. It builds the habit of drawing and reading forces carefully.
What children practice
- Tell balanced forces from unbalanced forces on a diagram
- Name gravity, normal force, friction and applied force from arrows
- Add and subtract force arrows to find net force
- Use F = ma to find force, mass or acceleration
- Identify action and reaction pairs and equal reaction forces
- Separate up, down and sideways forces to decide how things move
Levels
- Level 1: Balanced or unbalanced
- Level 2: Name the force
- Level 3: Find the net force
- Level 4: Force and acceleration
- Level 5: Action and reaction
- Level 6: Up, down and sideways
How it works
- Six levels grow from balanced and unbalanced forces to up, down and sideways forces.
- A level unlocks after five correct answers and the practice timer.
- A wrong answer shows a try again message so your child can choose again.
- The speaker button reads each prompt, and the explanation after a correct answer shows the reasoning.
Best for: A good fit for grades 5 to 9, from a child first meeting pushes and pulls to a student practicing net force and Newton's laws.
Tip for parents: Ask your child to draw the forces on a book resting on a table, then on the same book being pushed across it. Comparing the two drawings shows what changes when forces become unbalanced.
Questions parents ask
Does Force Diagrams include calculations?
Yes. Levels 3 and 4 ask for net force and use mass and acceleration in newtons and kilograms. Level 6 asks for horizontal net force and acceleration. Levels 1 and 2 are conceptual and need no calculating.
What does the game say about action and reaction?
Level 5 gives an action, such as one object pushing another, and asks for the reaction force. It also asks whether weight and the normal force are an action-reaction pair, and which object feels the bigger force.
Will my child need to know Newton's laws first?
Not to begin. The first levels build the ideas from pictures and arrows, and each correct answer gives a short explanation. A child who has heard of the laws will move faster through the later levels.
