text: -- If you're actually thinking about an object that's "falling", with no air in the way and no other influence on it except gravity, then its acceleration is constant as it falls.
text: The acceleration due to gravity is a constant over some kilometers from the surface of earth.
text: Here the acceleration is constant.
text: Here the acceleration is constant.
text: These equations are true if the acceleration of the body in question is constant (i.e. it doesn’t change over the time period).
text: All the rockets ignite and forward acceleration is constant at 3g's.
text: In cases where acceleration is constant at some non-zero value, velocity will be changing.
text: how do the numbers in the table show that the acceleration was constant?
text: The speed increases by a constant value of 0.60 m/s every one second, hence the acceleration can be seen to be constant.
text: When acceleration is constant:
text: It will be accelerated by gravity, which is a constant force, so the acceleration of the stone will be constant, until it hits terminal velocity of course at which point it will no longer be accelerating as the net force (gravity versus air resistance) would be zero.
text: Also, in response to number 2, I don't think that acceleration has to be constant in mechanics.
text: In the case of a contant increase in speed/velocity, the acceleration is constant (because the "slope" of the velocity change is a contant).
