    Study Notes

    Motion and Forces

    • The distance moved by an object in unit time indicates its speed.
    • A goalkeeper stops a ball by applying a force to change its motion.
    • Actions like kicking, hitting, and pushing result in a force being applied to an object, causing it to change its motion.

    Understanding Forces

    • A force is a push or pull that can cause an object to change its motion or shape.
    • A force can make an object slow down or speed up, depending on its direction and magnitude.

    Stopping Objects

    • Fielders stop a ball hit by a batsman by applying a force to the ball, typically by catching or deflecting it.
