Just apply a different force onto the original one, or similarly, change the magnetic field would mean the same as well
Source: Newton's First Law: Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

The unbalanced force on an object will cause a change in direction towards the lesser force

The electric force would decrease by a factor of 9 because the electric force is inversely proportional to the square of the distance between two charged objects. Triple the distance means the force would become 1/3^2 = 1/9 of the original force.
Changing an object's direction without affecting speed requires a force that acts perpendicular to the object's velocity, such as centripetal force or gravitational force. This force causes the object to change direction while continuing at a constant speed. Other forces acting parallel to the object's velocity can change its speed as well as its direction.
Gravity Electro-magnetic force Direct impact or contact
If the force on the right sled were larger, its acceleration would increase. This is because acceleration is directly proportional to force according to Newton's second law of motion. The larger force would result in a greater acceleration of the sled.
The force that can change an object's position is an unbalanced force.
The change in momentum can be calculated using the formula: change in momentum = force x time. In this case, the change in momentum would be equal to 20N x 4s = 80Ns.
At the instant the centripetal force disappeared, the moon would take off in a straight line into space, and would never be seen or heard from again.
That is correct. Any non-zero force would cause an acceleration (change of velocity).
