Under what condition(s) is the instantaneous acceleration throughout an interval (say 5 s long) equal to the average acceleration calculated over that interval?
if the body moves with constant accelaration,then average accelaration = instantaneous accelaration
There can be 2 cases:
1) The body must be moving under constant acceleration. Hence, instantaneous acceleration at any instant would be the same as the average acceleration of the body in its journey.
2) If the body is moving with variable acceleration, say the graph of acceleration vs time has several ups and downs, we draw a line of a = aavg . The number of points of intersection of this line with the graph give the instants at which the instantaneous acceleration = average acceleration.

What can we say about velocity under constant acceleration? (multiple answers are allowed) a. Has to point in the same direction as acceleration. b. Must always be constant. c. It could be increasing, decreasing, or staying constant. d. It could be positive negative or zero.
The position of a particle moving with constant acceleration is given by x(t) = 2t2 + 4t + 4 where x is in meters and t is in seconds. (a) Calculate the average velocity of this particle between t = 2 seconds and t = 4 seconds. 16 m/s Correct: Your answer is correct. (b) At what time during this interval is the average velocity equal to the instantaneous velocity? (c) How does this time compare to the average time...

5) Acceleration is to velocity as velocity is to position . aaux"# r where vr įs the instantaneous velocity. So the average acceleration is about how rapidly the instantaneous velocity is changing, and the sign tells about the direction of the change. At For the pendulum, you made estimates of the instantaneous velocity for ←2.05[s] and t= 2.5%]. Also, the average speed and average velocity estimates that you made at other times may be reasonable...

An object moving in the *x direction experience an acceleration of *2.0 m/s^2- This mean the object is increasing its velocity by 2.0 m/s every second. travels 2.0 m In every second. is traveling at 2.0 m/s. is decreasing its velocity by 2.0 m/s every second. Suppose that an object is moving with a constant velocity. Which statement concerning Its acceleration must be correct? The acceleration is constantly increasing. The acceleration is a constant non-zero value. The acceleration is constantly...
Let's say you measure an average acceleration to be 0.4166 ms-2. What is the height (in centimeters) of the riser block? Assume the legs of the track span 1.0000 m and that there is neither friction nor drag. Also assume the block is under one of the legs. Answer in cm.
