That would be the case if the object moved only among a straight line, and only in one direction (i.e., it didn't move back and forth).
The definition of speed is the size/magnitude/measure of an object's velocity. Average speed = distance divided by time
Then you can say that the object's speed and the magnitude of its velocity are constant, and the magnitude of its acceleration is zero.
Distance divided by time has the dimensions of speed (magnitude of velocity). The (distance an object travels) divided by (the time it takes to travel that distance) is a definition for the object's average speed.
the slope show the velocity of the object which show its direction and magnitude.
It equals an undefined entity. The average acceleration of an object equals the CHANGE in velocity divided by the time interval. The term "change in velocity" is not the same as the term "velocity", "average velocity", or "instantaneous velocity".
The velocity of an object has two attributes, 1. its magnitude and 2. its direction. The difference betwen the velocity and the magnitude of the velocity is the direction!
Average velocity equals the average speed if (and only if) the motion is in the same direction. If not, the average speed, being the average of the absolute value of the velocity, will be larger.
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
1. magnitude of distance covered is equal to the magnitude of displacement. 2. the motion of the object is in a straight line i.e. in a particular direction.
The definition of speed is the size/magnitude/measure of an object's velocity. Average speed = distance divided by time
The magnitude and direction of the object's velocity vector.
Acceleration is the change in velocity of an object over time. Take note that velocity is a vector quantity which means that it has magnitude and direction...Thus...An object undergoes acceleration when:1. there is a change in the magnitude of the velocity (speed) of an object.2. there is a change in direction of an object.3. it changes both in direction and magnitude.
That's the magnitude of its acceleration.
"Acceleration" implies that the velocity changes.
If the velocity is zero, the object is not moving. So if it moves at all, it is changing direction.
Speed is the magnitude of distance travelled per unit time, whereas velocity depends on the magnitude of distance travelled as well as the direction of motion. Speed is a scalar quantity, velocity is a vector. Speed cannot be negative, velocity can be negative. Average speed of an object after travelling a certain distance is always non-zero, but for velocity the average velocity can be zero (this follows from the previous idea).
Always.
