- What can electricity moving through a wire create?
- Where is the Earth's magnetic fields the strongest?
- What can magnets moving by a wire create?
- the starting point you choose to describe the location, or position, of an object
- distance depends on the path taken and displacement depends only on the initial and final positions
- the speed and direction of a moving object
- the difference between the initial position and the final position of an object
- a measure of the distance an object travels per unit of time
- Choose a starting and end point. Determine the change in distance and time. Substitute them into the average speed equation.
- by using 2 reference directions and 2 directions, you can use ¨right¨ or ¨forward¨, also ¨left¨ or ¨up¨ as reference directions
- Velocity changes when speed, direction, or both speed and direction change.
- the starting point you choose to describe the location, or position, of an object. A description of position depends on a reference point because if the reference point changes than the distance and direction can change.
- a measure of the change in velocity during a period of time
- the rate of change of position in which the same distance is traveled each second
- What is the perceptual equivalent of frequency?
- What is the perceptual equivalent of amplitude?
- the mass of the individual nucleons-mass of nucleus =
- Uses of optical fibers include ____________ and __________
- Light that enters the human eye is focused on the __________ of the eye
- Lasers produce__________ light in which the waves are aligned and travel in the same direction
