Forces and motion
Across
- 2. Energy is transferred from one object to another when a reaction takes place. Energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few
- 7. A resultant vector is the combination of two or more single vectors. When used alone, the term vector refers to a graphical representation of the magnitude and direction of a physical entity like force, velocity, or acceleration
- 9. strength or energy as an attribute of physical action or movement
- 11. how far away something is
- 13. the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration
- 15. the distance of which it takes for the driver to brake
- 17. for every action there is a equal and opposite reaction
- 19. the distance of which the driver thinks about braking
- 20. when the speed of an object increases
- 21. the quantity of motion of a moving object
- 24. two forces acting on an object that are equal
Down
- 1. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force
- 3. having only magnitude, not direction
- 4. the resistance that one surface or object encounters when moving over another
- 5. a quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another
- 6. air resistance is the forces acting against an object moving through the air
- 8. the distance it takes which to stop
- 10. two forces of different strength
- 12. the gravitational force on an object
- 14. local rate of change
- 16. Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object
- 18. a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force
- 21. the force of an object
- 22. the speed of something in a given direction
- 23. how fast an object is moving
