Explanation:

It is necessary for a force to give impulse for the object to move, achieve speed and acceleration.

The movement can be modified at any time by changing the object's position.

The word "speed" refers to the ability to move quickly. This means that every object with speed has the ability to move very fast.

A reference point can be used to determine if an object is in motion or at rest, but it cannot be used to determine the time traveled by an object.

Anything that remains at rest, that is, remains stationary can be used as a reference point to determine whether another object is at rest or in motion.

The reference point does not need to move with the moving object, it is possible that it will be used even in repayment.

The speed is calculated by the ratio between the displacement (ie distance traveled) of an object and the time spent at that moment.

Objects may have displacements at low speeds, but not zero.

A long distance trip requires more time.

There are several objects on earth that are at rest in relation to different points of reference.
