Question

WHat type of force is needed for acceleration.?

Answer 1

any type of force can cause acceleration of something in some direction. However if there is an equal and opposite force, the net acceleration will be zero.

Answer 2

F=ma    (Newtons Law, I think the second)

F/m=a

Any force put on an object will cause acceleration.

But, if the sum (sigma) of the forces is zero, the mass is at constant velocity.

Answer 3

Any force can cause it

Answer 4

Any force will do the job as long no other forces are acting upon it. For example, an electric field will accelerate a proton, but if another electric field, which is equal but opposite in magnitude, is present, then the proton will move nowhere.
