• Momentum


  The quantity of motion that an object has
• Momentum


  Mass in motion
• Momentum


  • Depends on mass and velocity
  • Directly proportional to mass and velocity
• Impulse


  The multiplication of applied force and time interval it applied
• Change in momentum


  Impulse
• Situations involving momentum and impulse


  • Riding a bus on a curvy road
  • Bus travelling on a straight road
  • Change in number of passengers on the bus
• When an 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
• Impulse = Change in Momentum
• For a fixed value of the change in momentum, the impact force is smaller when the impact time is bigger while the impact force is bigger when the impact time is smaller
• Impulse - A special name is given to the product of the force applied and the time interval during which it acts.
• I=ft - In physics, an external force acting on an object over a specific time leads to a change in momentum of the object.
• • It states that the net force is directly proportional to the mass of a body and its acceleration. f =ma Do you still remember Newton’s Second Law of Motion? and in equation form?
• same change in momentum - same impulse invariably leads to the
• Momentum depends upon the variables
