Newton s 1 st law of motion
Newton’s 1st Law of Motion

  • An object at rest will stay at rest, unless an outside force is placed on it.

  • Commonly known as Inertia

Sport examples:

  • Statics – athlete/object is motionless

    • Olympic lifter

    • Diver before a dive

    • Gymnast after the landing

  • Dynamics – athlete/object is in motion.

    • Cyclist coasting at a constant velocity

    • Skier coasting at a constant velocity


  • Newton s 2 nd law of motion
    Newton’s 2nd Law of Motion

    • Is the most complicated of the laws

    • The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

    • The change of motion of an object is proportional to the force impressed; and is made in the direction of the straight line in which the force is impressed.

    • Formula

      • F=ma

    • F = Force (1N)

      • 1lb = 4.5N

    • m = mass (kg)

      • 1kg = 2.2 lbs

      • Weight = mass x acceleration of gravity

      • W = mg

      • W = 1 kg x (9.8 m/s2) = 9.8 N

    • a = acceleration of gravity

      • 9.8m/s2 or 32.2 ft/s2

    • What is a Force?

      • A vector defined by the size and direction

      • A → to the right (+) or a ← left (-). The length = the force. The longer the line the greater the force, and vice versa on shorter

      • The same for the Up ↑ (+) and the down ↓ (-) arrow.

    •  There are different types of force:

      • Tensile Force (Pulling a rope) 

      • Compressive Force (Pushing together) 

      • Non contact forces – Gravity, magnetic forces, electricity


    Newton s 2 nd law of motion cont1

    • Net Force = the sum of all external forces acting on an object.

      •  F = F1+F2+F3+…..

      • Statics – Bodies at rest equal zero

        •  F = 0

    • Collinear forces – in the same line, maybe in the same or opposite direction and may be added to determine resultant force.

    • Example:

      • Tug –of – War Team 1 has 3 members exerting the following forces: 100N, 200N, 400N and team 2 has 3 members exerting the following forces: 200N, 300N, 500N; who will win?

      • Team 1 Team 2

        (-100N + - 200N + -400N ) + (200N + 300N + 500N )

        (-700N) + (1000N)

        = 300N

    • Team 2 is the winner due to 300N more force.

    • Pitching a baseball

      • How fast is the ball moving?

    • Weightlifting

      • How much force do I need to lift this weight?

    • Track and Field

      • How fast is that person running?

      • How much force is needed to throw the shot-put 50 feet?


    Newton s 3 rd law of motion
    Newton’s 3rd Law of Motion

    • For every action, there is an equal and opposite reaction.

    • Action equals Reaction
