5.7.1 Momentum

• What is momentum a measure of?

  How difficult to stop a moving object
• Momentum is the product of an object's mass and velocity
• What is the formula for calculating momentum?

  $p =$$m \times v$
• Match the quantity with its symbol and unit:

  Mass ↔️ m and kg

  Velocity ↔️ v and m/s

  Momentum ↔️ p and kg m/s
• The greater the mass of an object, the greater its momentum.
• What are the units of momentum?

  kg m/s
• The units of momentum are derived from the formula $p =$$m \times v$
• The units of momentum are the product of mass and velocity units.
• How is momentum calculated?

  Multiply mass by velocity
• What two quantities does momentum depend on?

  Mass and velocity
• What does momentum measure in physics?

  How difficult to stop a moving object
• What is the unit for velocity in physics?

  m/s
• Momentum is measured in kilograms meters per second
• A car with a mass of 1000 kg and a velocity of 20 m/s has a momentum of 20,000 kg m/s.
• What is momentum a measure of?

  How difficult it is to stop a moving object
• In the momentum formula, $p$ represents momentum
• The units of momentum are derived from the product of mass and velocity.
• What are the units of momentum in the SI system?

  kg m/s
• What is the formula used to calculate momentum?

  $p =$$m \times v$
• In the momentum formula, $m$ represents the mass
• What does $v$ stand for in the momentum formula?


  Velocity
• An object with a mass of 5 kg and a velocity of 10 m/s has a momentum of 50 kg m/s.
• What does the law of conservation of momentum state?

  Total momentum remains constant in a closed system
• The law of conservation of momentum applies to a closed system.
• What is the unit for mass in the momentum formula?

  kg
• In an open system, the total momentum is conserved.

  False
• What is the formula for momentum?

  $p =$$m \times v$
• The unit for momentum is kilogram meters per second
• Match the type of system with its characteristic:

  Closed System ↔️ Total momentum is conserved

  Open System ↔️ External forces can act
• What does the law of conservation of momentum state?

  Total momentum is constant
• In an open system, total momentum is not conserved
• In a closed system, the total momentum changes unless an external force acts on it.

  False
• What happens to the total momentum in a closed system when two objects collide?

  It remains the same
• What does 'p' represent in the momentum formula?

  Momentum
• What does 'm' represent in the momentum formula?

  Mass
• What does 'v' represent in the momentum formula?

  Velocity
• In a closed system, external forces can act on the system.

  False
• In an open system, the total momentum is not conserved
• Match the system with its description:

  Closed System ↔️ Total momentum is conserved

  Open System ↔️ External forces can act
• How is momentum calculated?

  $p =$$m \times v$
