  1. 1. _____ is the measurement of a push or pull on an object. It is a vector measured in newtons.
  2. 2. A _____ is a measurement that only measures the magnitude. Unlike a vector, it does not have direction.
  3. 5. _____ is the resistance of motion when one object rubs against another. It is a force and is measured in newtons.
  4. 8. _____ occurs in physics when a force acts on an object to move it some distance. It is equal to the force times the distance and is measured in joules.
  5. 10. _____ is the _____ 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.
  6. 13. _____ is the force of gravity on an object. In physics, it is measured in newtons.
  7. 14. _____ is the rate of change in an object's position. It is a vector quantity. The magnitude of it is the object's speed.
  8. 17. The ___ ___ __ ____ states that the greater the mass of an object, the more force it will take to accelerate the object.
  9. 22. _____ _____ is the energy stored by an object due to its state or position. It is measured in joules.
  10. 23. _____ is a measurement of how much matter is in an object. It is usually measured in kilograms.
  11. 24. A _____ in physics occurs when any two objects bump into each other.
  12. 25. _____ is the measurement of how fast on object moves relative to a reference point. It is a scalar quantity measured by distance over time.

  1. 1. The ___ ___ ___ ___ states that any object in motion will continue to move in the same direction and speed unless external forces act on it.
  2. 3. _____ is a force caused when the mass of physical bodies attract each other. On Earth it pulls at objects with an acceleration of 9.8 m/s2.
  3. 4. _____ is the force over a given area. It is measured in pascals.
  4. 6. _____ is the ability to do work. The standard unit of measure for it is the joule.
