when an object changes its motion it is because a new force that is greater than the original force has been applied to the object and that object changes its motion unless the force is in the same direction as the original force, which would then imply that the object stays in the same direction of motion, but moves at a greater speed in that direction.
"reference"
You have to use a reference point. Pick anything around the area (it's better if it's stationary), and then check to see if the other object changes position at all (in comparison to the reference point). If it does change position, then the object is in motion.
because everything around has motion because the word motion comes from the word movement when we move its motion but we do not see motion so therefore motion is a force just like gravity because gravity is what pulls every object to the ground. when we push or pull it is force and that is motion pulling or moving an object is motion.
If you have a DVD player or a Blu-ray player and it has a slow motion option, you can see DVD/Blu-ray movies and TV shows in slow motion. Otherwise it's very difficult to see an object in slow motion, without the aid of a special device.
In the animation above we see an object (blue box) that is already moving along when we encounter it.
This is called relative motion. Relative to your frame of reference, the object's motion appears unchanged, even though it's motion has actually changed.
Its position.
"reference"
The 1 way you can tell an object is in motion is by having a focus point that does not move and watch and see if the object you are looking for is moving. Another way to notice where the object is now, then later, check and see if the object has been moving. lastly, if you are a scientist, you can use telescopes, computers, and the latest gadgets to tell you if an object is in motion.

Inertia and friction are related in the sense that friction opposes the motion of an object due to inertia. Inertia is the tendency of an object to resist changes in its state of motion, while friction is the force that opposes the relative motion of two surfaces in contact. The presence of friction can affect an object's motion by counteracting its inertia and slowing it down.
If the sum of all forces on an object is zero, then the object remains in constant, uniform motion. 'Constant uniform motion' means motion in a straight line at a constant speed. The physical description of such motion is "constant velocity". "Rest" is just constant velocity with a speed of zero. If the sum of all forces on an object is NOT zero, then the object's velocity must change. The change may consist of speeding up, slowing down, or turning in a different direction. Note: If you can, you should try and find the question in writing, so you can see what it's really asking.

you have to look around the area were the object mite have been at
Motion is graphed by using time on one axis and location on the other axis.
Because Newton's 1st law of motion is... An object at rest will stay at rest unless acted on by an ublanced force. An object in motion will stay in motion and the same direction unless acted on by an ublanced force.
