3 m/s
To find the average speed between time=0 and time=2, divide the distance traveled by the time (in this case 2 seconds).
Speed and Velocity are two words that mean the same. You may mean, "Can Velocity be 0 but acceleration not 0". Yes, this occurs when a moving object is changing direction (say from moving forwards to moving backwards) or is just about to move or, at that very instant has just come to a halt. In all these cases, speed /velocity is zero but the body is accelerating. Don't forget, the word acceleration is also used when an object is decelerating (slowing down).
0
0
0 divided by 5 equals 0. 5 divided by 0 equals undefined, not 0.Any number divided by 0 is undefined.
The correct term is velocity, not velocity.There is no reason why an object cannot have 0 velocity and 0 average speed - relative to some fixed reference point. I assume that your school, for example, has 0 velocity and 0 average speed.
An object at a constant speed has no net force acting on it because the forces are balanced. When there is no net force, the object will continue to move at a constant speed due to inertia, which is the tendency of an object to maintain its state of motion.
0 m/s
That depends upon what the object has done for the 20 seconds since t = 0 seconds.
haha 0
The speed of an object at rest is 0 m/s. When an object is not moving, its speed is considered to be zero.
Yes. Acceleration is independent of speed. A perfect example of an object with zero speed but nonzero acceleration is an object at the apex of being thrown upward. The entire time it is in the air it is accelerating downward. At its maximum height its speed is zero.
An object moving at a constant speed in a straight line has an acceleration of 0. An object at rest also has an acceleration of 0. So, the two things I see in common are their accelerations, which are both 0.
0 m/s
When a graph of speed starts at the point (0, 0), it indicates that the object is at rest at the initial time, meaning its speed is zero at that moment. As time progresses, any increase in speed from this point would suggest acceleration. Conversely, if the graph remains at (0, 0) for a period, it means the object has not started moving. Overall, this point signifies the starting condition of the object's motion.
In the frame of reference in which the object is stationary, its speed is zero. (Actually, that's kind of a definition of "stationary".)
Average velocity is 0 when an object returns to its starting point after moving away from it. This means that the total displacement of the object is 0, resulting in an average velocity of 0.
