4. Momentum and Impulse

• What is the measure of ones motion?

  Momentum
• What is the symbol for momentum?

  p
• Momentum depends on two variables and they are?:

  mass - how much an object is moving

  velocity - how fast the object is moving
• Momentum is also known as a?

  Vector quantity
• An object moving to the right (east) has what velocity?

  Positive (+v)
• An object moving to the left (west) has a what velocity?

  Negative (-v)
• p - momentum (kg m/s)

  m - mass (kg)

  v - velocity (m/s)
• What is force applied by an object to another that causes it to move at a given time interval?

  Impulse
• What is the symbol for Impulse?

  I
• Impulse is also known as?

  Change in momentum
• I - impulse (kg m/s)

  p^2 - final momentum (kg m/s)

  p^1 - initial momentum (kg m/s)
