  • Effects of Force in the Direction of Motion: Speed, Energy & Work
    If a force pushes an object in the same direction as its motion, here's what will change:

    * Increased Speed: The object will accelerate, meaning it will move faster.

    * Increased Kinetic Energy: The object will gain kinetic energy, which is the energy of motion. This energy is proportional to the object's mass and the square of its velocity.

    * Work Done on the Object: The force will be doing positive work on the object, meaning it is transferring energy to the object.

    Example: Imagine pushing a box across a floor. If you push in the same direction the box is already moving, you'll make it move faster.

    Important Note: If the force is constant, the acceleration will also be constant. This means the object's velocity will increase at a steady rate.
