5 m/sec
More correctly: 5 m/sec2
an object uniformly accerlerates over a distance of 100 m in 20 seconds. calculate the acceleration.
Change of speed divided by time gives you average acceleration. For example, a change of 30 m/s during 5 seconds gives you 6 meters per second square - this is the average acceleration during those 5 seconds. If acceleration is constant, then this is also the acceleration at any moment during those 5 seconds. For more complicated functions (non-constant acceleration), derivates (a topic in calculus) has to be used. Specifically, the acceleration is the derivative of the velocity.
Certainly! By definition, the acceleration is the change, so it will change unless that amount is zero.
Acceleration = (change in velocity) / (time for the change)9.8 = (change in velocity) / (2 seconds)9.8 x 2 = change in velocity = 19.6 meters per second .Hint: The mass of the object and the height of the building are there just tothrow you off balance. You don't need either of them to answer the question.

Acceleration is change of velocity / time.
Acceleration is the change in velocity and/or What_three_ways_can_acceleration_change_an_objects_motionof an object. Acceleration can either speed an object up, slow it down (deceleration), or change the direction in which the object is moving.
As mass increases acceleration decreases.
Velocity. A change in VELOCITY will always indicate the acceleration of an object.
Velocity can only change if the object experiences an acceleration. Acceleration can only change if either the Force on the object increases, or the Mass of the object decreases.
No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.
When an object moves in a circular path, the velocity will change and the there will be acceleration.
Acceleration is "force divided by mass" or "change in velocity with respect to change in time".

Acceleration.
Force can change the acceleration of an object a =F/m.
I am not sure what you mean by reversing a zero acceleration. An object's acceleration can, of course, change over time.
