Newtons three laws

  1. 1. by Ryan Perkins Page 1
  2. 2. Newton’s Laws of Motion• Law 1: Every material object continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it.• Law 2: The acceleration of an object is directly proportional to the net force acting on an object, is in the direction of the net force, and is inversely proportional to the mass of the object.• Law 3: Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.

  3. 3. Law 1• Every material object continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it.• Mass- The quantity of matter in a material object.• Weight- The force upon an object due to gravity.• What is the difference between mass and weight?

  4. 4. Law 2• The acceleration of an object is directly proportional to the net force acting on an object, is in the direction of the net force, and is inversely proportional to the mass of the object.• Force- Strength or energy as an attribute of physical action or movement• Acceleration- Increase in the rate or speed of an object.

  5. 5. Law 2• The force of one hand accelerates the brick.• Twice as much force produces twice as much acceleration .• Twice the force on twice the mass gives the same acceleration. Page 5

  7. 7. Law 3• Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.• The action and reaction of forces make up the interaction between two things. Page 7

  13. 13. Summary• An object at rest will remain at rest.• An object in motion will remain in motion.• When a force is applied to an object, it will accelerate.• When an object falls in air, the force is equal to the weight minus the force of air resistance.• When one object applies force on a second object, the second object applies the same force back.
