Speed is a measure of how fast an object is moving in a certain direction. It does not explain the cause of the motion, but rather describes how quickly the object is changing its position over time. Understanding speed helps us quantify and compare different rates of motion.
Motion and speed are synonymous terms, with just a slight difference of emphasis. Speed suggests fast motion. Other than that, they are the same thing. Speed is a form of motion, so in that sense, motion does crreate speed. Obviously, an object that is not moving has a speed of zero.
The speed increases. The object accellerates positively in the direction of motion.
Short answer: yes. An object in "motion" has a "speed" simply by virtue of its being in motion. An object possessing a speed is inherently in motion. In this sense they have similar meanings. Speed is a rate of change in position. Motion is a change in position (in progress). In this sense, speed is more specific than motion in that speed has a quantitative value. Conversely, there can be no "speed" without "motion". To be complete, "velocity" is even more specific than speed in that it contains a rate of change in position together with a direction. That is, speed is a "scalar" quantity, and "velocity" is a vector quantity.
A change in speed or direction of motion is called "acceleration". If an object's speed or direction of motion changes, then the object is "accelerated".
it is speed of motion and direction of motion
An objects speed or motion is measured by distance divided by time.
A balanced group of forces acting on the object has no effect on its motion. The object continues moving in a straight line at constant speed.
That is the object's 'speed'.

When a moving object is pushed in the direction of its motion the speed of the object increases

If the speed of an object is cited and its direction of motion is also cited, we have the velocity of the object. Velocity is speed plus a direction vector.
