An object will continue accelerating as long as there is a force acting on it.
(Newton's Second Law)
An object will accelerate in the direction of the net force acting on that object.
No, it is not harder to accelerate a moving object. The initial motion of the object does not affect the force required to accelerate it further. The force required to accelerate an object depends on its mass and the desired acceleration.
Accelerate, motion is generated by applying force to mass.
... to accelerate.... to accelerate.... to accelerate.... to accelerate.
Velocity must be changing in order for an object to accelerate or decelerate.
When the forces on an object are unbalanced, the object will accelerate in the direction of the net force.
an object can accelerate both up and down
An object will accelerate in the direction of the net force acting upon it. If multiple forces are acting on the object, the net force is the vector sum of all the individual forces, and the object will accelerate in the direction of this net force.
... then it won't accelerate.... then it won't accelerate.... then it won't accelerate.... then it won't accelerate.
... then it won't accelerate.... then it won't accelerate.... then it won't accelerate.... then it won't accelerate.
Yes. If there is an unbalanced force on an object, the object will always accelerate in the direction of the force.
It will accelerate in the direction of the resultant (net) force.
