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
