  • Newton's Second Law: Understanding Acceleration, Velocity, and Displacement
    When a constant force acts on a mass that starts from rest, the following things happen:

    * Acceleration: The mass will accelerate in the direction of the force. This acceleration is constant and is determined by Newton's second law of motion: F = ma, where F is the force, m is the mass, and a is the acceleration.

    * Velocity: The mass will gain velocity over time. Since the acceleration is constant, the velocity will increase linearly with time.

    * Displacement: The mass will undergo displacement or change in position. The displacement will increase quadratically with time because the velocity is increasing linearly.

    * Kinetic Energy: The mass will gain kinetic energy. Kinetic energy is the energy of motion, and it increases as the velocity of the object increases.

    In summary, a constant force acting on a mass at rest will cause it to accelerate, gain velocity, change position, and gain kinetic energy.
