When an object is moving at constant acceleration...?

Question

When an object is moving at constant acceleration, is it accelerating or is it moving with a same speed? Why?

Answer 1

If the acceleration is constant it means the object is speeding up. Only if the acceleration is zero,it means the speed is constant.

Answer 2

It is accelerating, unless the constant acceleration is 0.

A satellite is in constant acceleration, but it is the vector velocity that changes, speed is the wrong term. You can have constant speed and still be under acceleration... as satellites are. Speed has magnitude but not direction.

Answer 3

Assuming the acceleration is not 0 then the object is continuously speeding up or continuously slowing down.

Answer 4

for the reason which you already know the acceleration is persevering with, consistent-acceleration kinematics equations may be utilized. individually, i do no longer think of this equation is properly worth remembering, yet i'm disinclined to derive it on the 2nd: (v_f)² - (v_i)² = 2 a (x_f - x_i) the place "i" represents preliminary states, and "f" represents very final states. we don't probable understand that's preliminary and that's very final in this difficulty. enable's %. the x = 2.6 m information to be preliminary, and the x = 4.8 m information to be very final. If we've picked incorrectly, we will finally end up with the different of the properly suited acceleration. remedy for "a": a = [ (v_f)² - (v_i)² ] / [ 2 (x_f - x_i) ] a = [ (80.9 m/s)² - (40 4.8 m/s)² ] / [ 2 (4.8 m - 2.6 m) ] = 456 m/s² which does look as though an poor lot. submit to in ideas that the respond may be -456 m/s², via fact the undertaking hasn't particular the time-order of the measurements.

Answer 5

Acceleration is defined as a change in speed over time. Ergo, the speed cannot be constant.

Answer 6

You just said that an object is accelerating and then asked us if it is accelerating.

Answer 7

Constant acceleration => getting faster at the same rate for every unit of time.

E.g.
0s => 0m/s
1s => 10m/s
2s => 20m/s
3s => 30m/s

Answer 8

yaa sure its accelerating when const acceleration is not equal to zero.... and speed will keep on increasing if acceleration is on the positive side and decrease if negative, get it??
