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
If 5n = 0 then n = 0, and any number of n's = 0.6n = 0
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.
If speed is constant, acceleration is zero. Anything multiplied by zero equals zero. F = m * a, where F is force, m is mass and a is acceleration. F = m * 0 = 0
An object with no movement at all has a zero speed or which have an constant speed. 0
haha 0
That depends upon what the object has done for the 20 seconds since t = 0 seconds.
0 m/s
0 m/s
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.
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.
We can only tell average speed from those two pieces of information. 3,000 miles in 5 hours equals an average speed of 600 mph.
0 velocity 0 acceleration The forces on the object are balanced: it is in equilibrium. (The forces are balanced on any object with 0 acceleration, even if it is moving.)
Velocity is defined as the rate of change of the position of an object in relation to the specification of its speed and direction of motion. Therefore, an object at rest will have zero velocity.
