Force and Motion Vocabulary 1. Force 2. Unbalanced force 3. Balanced force 4. Friction 5. Mass 6. Gravity 7. Magnetism Any push or pull by one object on another. Forces that do not cancel each other out and that cause an object to change its motion. Forces that act together on an object without changing its motion. A force that opposes the motion of one object moving past another A measure of the amount of matter in an object. A PULL that attracts objects to each other. The greater the mass of an object, the greater its gravity. The ability of an object to push or pull on another object that has the magnetic property 8. Position The location of an object. 9. Motion A change in an object’s position over time. 10.Frame of Reference A group of objects from which a position or motion is measured. 11.Speed How fast an object’s position changes with time at any given moment. 12.Velocity The speed and direction of a moving object. 13.Acceleration Change in velocity with respect to time. 14.Momentum How hard it is for an object to stop moving. The mass of an object multiplied by its velocity (Mass * Velocity = Momentum)
