physics

• Momentum


  Quantity equal to the product of mass and velocity
• Momentum is conserved in collisions
• Momentum is involved in collisions
• Newtons


  Unit of force
• Resultant force


  The single force that would have the same effect as all the forces acting on a body
• Mass


  Quantity of matter in an object
• Final momentum

  Momentum of an object after a collision
• Force is equal to mass times acceleration
• Time is measured in seconds
• Acceleration

  Rate of change of velocity
• Mass x velocity


  Formula for calculating momentum
• Momentum is measured in newtons
• Newton's second law

  The rate of change of momentum of an object is directly proportional to the applied unbalanced force in the direction of the force
• Momentum is conserved unless a resultant force acts
• Momentum is a useful quantity
• Velocity


  Rate of change of position
• Initial momentum

  Momentum of an object before a collision
