Impulse and Momentum

• Momentum - Any moving object with a quantity of matter has momentum. Momentum simply means "mass in motion." It is equal to the product of mass and velocity.
• Mathematically, it is expressed as 𝒑 = M × V
• If any object of any mass is not moving, it has zero momentum since its velocity is zero.
• Therefore, when the object slows down or moves faster, its velocity decreases or increases.
• If there is a change in the velocity or the mass of an object, there is also a change in momentum.
• That change of momentum is called Impulse.
• Constant means there is no change. Therefore, there is no impulse or zero impulse for objects moving with constant momentum.
• Momentum - •It describes an object’s resistance to stopping

  (motionless)
• It is represented by the symbol p
• •It is the product of mass and velocity
• •The SI unit of momentum is kg •m/s
• •It is considered as a vector quantity
• •Word momentum is a latin word

  means, movement or moving power
• •The symbol p stands for progress
• •It was first used by German Scientist

  Gottfried Wilhelm von Leibniz
• Newton’s Second Law of Motion

  – The acceleration of an object is directly

  proportional to the net force acting on the

  object and inversely proportional to the mass

  of the object
• The formula is F=ma
• SI unit for Force is Newton or kg•m/s2
