Do objects in motion always change position and may change direction?
Objects in motion continuously change position.To change direction, a force needs to act upon them.
What must be applied to a objects in order change the objects motion or direction?
A Force.
Can force cause change in an objects direction?
Yes
Why do waves change direction when they are near shore?
The reason they change direction near shore is because the density of objects increase!
How can an objects velocity change?
By changing its direction.
Is velocity a change in an objects motion?
Velocity is a change in an object's motion OR direction of motion.
What do you call it when an objects velocity changes?
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
What is a force that causes an object to change its motion?
I think this question is not phrased very well. Any force can change objects velocity (speed+direction). If fact that is the definition of the force - F=ma any force, by definition itself, can change objects velocity. Maybe you meant what force can change objects direction of motion? In that case - any force that has a different direction (not the same as direction of motion) Any force can change an object's motion.
How does gravity keep objects in motion?
It doesn't. It will change an objects direction and/or speed but its inertia that keeps it moving.
What type of force CAN a change in an objects direction speed or both?
gravitey
Is it true a balanced forces do not change an objects direction?
Yes, that is correct.
What vector represents the distance and direction of an objects change in position?
velocity
