What can cause the direction of an object moving in a straight line to change?
An outside force.
What happens to the direction of motion of the ball what changes it direction of motion?
A force acting on the ball, at an angle to its line of motion, will cause its direction of motion to change.
What is the job of the single pulley?
A single pulley system is used to change direction of the pulling force line.
What does change in motion mean?
It means any change in -- speed -- direction -- or both. Constant or 'uniform' motion means steady speed in a straight line.
What happens when sound reflects and refract?
In that case, it will change direction - move differently than just in a straight line.
What is a line that does not change direction?
a straight line
What is edge speed in electronics?
A voltage is applied to a signal line. The voltage of the line changes gradually from 0 to +V. The "edge speed" is the rate of change of voltage of the line. A voltage is applied to a signal line. The voltage of the line changes gradually from 0 to +V. The "edge speed" is the rate of change of voltage of the line.
Why does a change of speed produce a change in direction?
It doesn't. For example, you can go in a straight line, and speed up or slow down, without changing direction. And if there is both a change in direction and a change in speed, the change of speed wouldn't be the CAUSE for a change in direction. (On the other hand, both can be caused by a force applied to an object.)

When Line of latitude run in a north south direction but are measured in what degrees?
No line of latitude is a north/south line. A move to the north or south is a change of latitude.
