Physics 101
Across
- 6. pair, The action force and the reaction force that occur in an interaction
- 7. Fake science that pretends to be real science.
- 10. fall, falling under the influence of gravity alone—falling without air resistance.
- 11. resistance, The force of friction acting on an object due to its motion in air.
- 12. speed, The speed at which the acceleration of a falling object terminates when air resistance balances its weight
- 14. Any object that moves through the air or through space under the influence of gravity.
- 16. time, The time that one’s feet are off the ground during a vertical jump.
- 18. The oval path followed by a satellite. The sum of the distances from any point on the path to two points called foci is a constant. When the foci are together at one-point, the ellipse is a circle. As the foci get farther apart, the ellipse becomes more eccentric
- 19. Likes to chase mice
- 20. of energy, Energy cannot be created or destroyed; it may be transformed from one form into another, but the total amount of energy never changes.
- 22. The quantity of matter in an object. More specifically, a measure of the inertia (or sluggishness) that an object
- 23. Flying mammal
- 25. Large marsupial
- 27. collision, A collision in which colliding objects rebound without lasting deformation or the generation of heat.
- 29. force, The combination of all forces that act on an object
- 30. A projectile or small celestial body that orbits a larger celestial body
- 33. The quantity of space an object occupies.
- 34. Mutual action between objects during which each object exerts an equal and opposite force on the other.
- 36. Man's best friend
- 37. Simply stated, a push or a pull.
Down
- 1. being without a support force, as in free fall.
- 2. Has a trunk
- 3. The speed of an object and specification of its direction of motion.
- 4. The percentage of the work put into a machine that is converted into useful work output.
- 5. velocity, terminal speed in a given direction, often downward.
- 8. The scientific unit of force.
- 9. The rate at which velocity changes with time; the change in velocity may be in magnitude or direction or both, and it is usually measured in units of m/s2
- 13. A general hypothesis or statement about the relation-ship of natural quantities that has been tested over and over again and has not been contradicted; also known ASA principle
- 15. Distance traveled per unit time
- 16. An educated guess; a reasonable explanation of an observation or experimental result that is not fully accepted as factual until tested over and over again by experiment.
- 17. The curved path followed by a projectile under the influence of constant gravity only.
- 21. force, The force that supports an object against gravity, often called the normal force
- 24. The resistive force that opposes the motion or attempted motion of an object past another object with which it is in contact, or through a fluid.
- 26. An arrow that represents the magnitude and direction of a quantity.
- 28. A synthesis of a large body of information that encompasses well-tested and verified hypotheses about certain aspects of the natural world
- 31. The force that an object exerts on a supporting surface (or, if suspended, on a supporting string), which is often, but not always, due to the force of gravity
- 32. The unit of mass. One kilogram (kg) is the mass of 1 liter (L) of water at 4°C
- 35. The property by which objects resist changes in motion.
