Every force causes acceleration, if it's not opposed and canceled by other forces.
Not necessarily. Changing direction does affect the velocity, which is acceleration and direction combined.
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
If there are no other forces that counter it, gravity will cause an acceleration - basically it will change an object's velocity.
The Newton is the unit for force. An unbalanced force is required to cause acceleration, which is a change in velocity.
Yes timing can delay your acceleration
Acceleration
Just the opposite. It will cause the acceleration to drop by 50%.
acceleration
Yes.
You get the force required to cause the given acceleration on the given mass.
Every force causes acceleration, if it's not opposed and canceled by other forces.
Not necessarily. Changing direction does affect the velocity, which is acceleration and direction combined.
ANY net force will cause an acceleration. If the force is reduced, there will be less acceleration, though.
Gravity
no
The acceleration of a charge. its radioactive decay
