    What is speed?

    Measured in metres per second, it indicates how far something travels in a specific time.

    How does average speed differ from instantaneous speed?

    Average speed is calculated over a distance, while instantaneous speed is the speed at a specific moment.

    What is a distance-time graph?

    A visual representation showing how distance changes over time.

    What happens to pressure as depth increases in a liquid?

    Pressure increases due to the weight of the liquid above.

    What is liquid pressure?

    The force exerted by liquid molecules acting in all directions.

    What is atmospheric pressure?

    The pressure exerted by the weight of air above a surface.

    How does temperature affect gas pressure?

    Increasing temperature causes gas molecules to move faster, increasing pressure.

    What is a food chain?

    A diagram showing the transfer of energy from one organism to another.

    What is interdependence in ecosystems?

    The reliance of organisms on each other for survival, growth, and reproduction.

    How do organisms adapt to environmental changes?

    Those best suited to changes survive and reproduce, while others may die or migrate.

    What is a niche?

    The specific role or position an organism occupies within its ecosystem.

    What is bioaccumulation?

    The buildup of toxic substances in organisms as they consume contaminated food.

    What is competition among animals?

    The struggle for limited resources like food, water, and space.

    What is the law of moments?

    In equilibrium, the sum of clockwise moments equals the sum of anticlockwise moments.

    What is pressure on a surface?

    The force applied over an area, affecting how much an object sinks or stays afloat.
