    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 speed when an object accelerates?

    The object's speed increases or decreases, affecting the slope of the distance-time graph.

    What is liquid pressure?

    The force exerted by liquid molecules acting in all directions.

    How does pressure change with depth in a liquid?

    Pressure increases with depth due to the weight of the liquid above.

    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 a food web?

    A complex network of interconnected food chains showing feeding relationships.

    What is interdependence in ecosystems?

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

    How do organisms adapt to environmental changes?

    Survival of the fittest leads to increased populations of well-adapted species.

    What is a niche?

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

    What is competition among animals?

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

    What is bioaccumulation?

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

    What is a moment in physics?

    The turning effect of a force applied at a distance from a pivot point.

    What is the law of moments?

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