For any object to change its motion, it must be accelerated and experiences acceleration. Note that a change in motion is a change in velocity. The object either speeds up, slows down or changes direction, and one of those or some combination is a velocity change. Only acceleration will change velocity. We need to offer the reminder that velocity is speed with a direction vector attached to it. An object can travel at a constant speed and be changing direction. This is a change in velocity because of the change of direction. And a change in velocity is, as stated, initiated by acceleration.
motion =)
A force is required to change an object's velocity.
Motion is a change in position.
Motion is the change in an object's position.
It is not necessarily a motion in itself... Variable speed refers to something that can change speeds, or that the speeds can be changed. There are many things that can be variable speed.
A net force from something outside of the system.
Velocity is a change in an object's motion OR direction of motion.
An object in motion stays in motion because it requires a force to change the motion. No force, no change.
If it is constant change in motion, it is acceleration.
It is a legal request to change something (usually phraseology) contained in a document already filed with the court.
Motion is the change in an object's position.
a force is something that you apply to an object- it can move-change shape-change direction-slow it down-make it faster
