  1. 2. energy - Kinetic energy is the energy an object has due to its motion. It is a scalar quantity calculated using the formula KE = ½ * m * v2, where m = mass and v = velocity.
  2. 4. - Weight is the force
  3. 7. - Velocity is the rate of change in an object's position. Velocity is a vector quantity. The magnitude of velocity is the object's speed.
  4. 8. - Mass is a measurement of how much matter is in an object. It is usually measured in kilograms.
  5. 9. - The pascal is the standard unit of measure for pressure.
  6. 10. - Gravity is a force caused when the mass of physical bodies attract each other. On Earth gravity pulls at objects with an acceleration of 9.8 m/s2.
  7. 12. energy - Potential energy is the energy stored by an object due to its state or position. It is measured in joules.
  8. 14. - Power is a measurement of the rate at which energy is used. Power is calculated by dividing work over time. The standard unit for power is the watt.
  9. 16. - The newton is the standard unit of measure for force.

  1. 1. - Momentum is a measurement of mass in motion. Momentum is equal to the mass times the velocity of an object. It is a vector measured in newton-seconds.
  2. 3. - A vector is a quantity that has both a magnitude and a direction.
  3. 5. - The joule is the standard unit of measure for energy and work.
  4. 6. - An impulse is a change in momentum.
  5. 11. law of motion - The third law of motion states that for every action there is an equal and opposite reaction.
  6. 13. - Speed is the measurement of how fast on object moves relative to a reference point. It is a scalar quantity measured by distance over time.
  7. 15. - The watt is the standard unit of measure for power.
