  Velocity
• Steps to calculate momentum

  1️⃣ Identify the mass and velocity

  2️⃣ Apply the formula: p = mv

  3️⃣ Calculate the momentum

  4️⃣ State the final answer

  Mass and velocity
• Momentum is a scalar quantity.

  False
• What is momentum a measure of?

  Effort to change motion
• The formula for momentum is p = mv


  True
• The unit of momentum is kilogram meters per second
• The direction of momentum is the same as the direction of velocity.


  True
• Momentum is a vector quantity because it has both magnitude and direction

  Increases momentum
• Momentum is a scalar quantity.

  False
• What does velocity measure?

  Speed and direction
• Momentum is a scalar quantity

  False
• The direction of momentum is the same as the direction of velocity
• Momentum is a measure of how much effort is required to change an object's motion
• What is the unit of mass?

  kg
• What is the formula to calculate momentum?

  $p =$$m \times v$
• Mass is a scalar quantity measured in kilograms
• Mass changes with velocity

  False
