Exploring Forces
Class 8 · Science
3 ideas in Class 8 Science, explained in plain words, with games and quizzes to practise.
Forces and Their Effects
Part of: Force Interactions
A force results when objects interact and can affect motion or shape.
Why it matters. Understanding forces helps explain how objects move, stop, float, and interact.
Try it in two minutes
- Name the objects interacting.
- Identify the force and its direction.
- Connect the force to the change you observe.
Try at home. With an adult, observe how a safe object slides on two different surfaces.
Contact and Non-contact Forces
Part of: Types of Forces
Forces can act through contact or from a distance.
Why it matters. Understanding forces helps explain how objects move, stop, float, and interact.

- Identify the force and its direction.
- Connect the force to the change you observe.
Try at home. With an adult, observe how a safe object slides on two different surfaces.
Gravity, Weight, and Buoyancy
Part of: Gravity and Liquids
Gravity pulls objects downward; liquids push immersed objects upward.
Why it matters. Understanding forces helps explain how objects move, stop, float, and interact.
