Motion is caused by forces. A stationary object does not move unless a force acts on it to start it going. Once it is moving, it carries on at the same speed and in the same direction unless a force makes it speed up, change direction or slow down and stop.

Answer 2

Forces cause motion. To move something, you need to apply a push or a pull, which is, by definition, a force. Without a force, the object will be immobile, or keep moving without speeding up.There are different types of motion: translational,rotational, periodic, and non periodic motion. A type of motion in which all parts of an object move the same distance in a given time is called translational motion. Examples are vehicles moving on a road, a child going down a bird flying in the sky.
