Are there any forces acting on you in the direction you are moving?

Maybe, maybe not. Forces don't happen because you're moving ... forces are what cause you to move. If there are no forces acting on you, then you keep moving whichever way you're moving, and your speed or direction don't change. If there are forces acting on you, then your speed and/or direction can change. If the force is in the same direction that you're already moving, you'll move faster (accelerate). If the force is in the direction opposite to the direction you're moving, then your speed will decrease. Does any of this sound surprising ???


When an object is acted on by unbalanced forces, the object will?

Move (or change direction/speed if it was already moving).


What force can do to moving objects?

Forces can change the way the body is moving. Speed it up, slow it down, change its direction.. it depends if the body is in equilibrium or not and what forces are already in play

Can force change the direction of a body?

Strictly you should ask whether a force can change the direction a body is moving in. The answer is yes.


What is any change in the speed or direction of a moving object?

This is one definition of acceleration (including deceleration) - any change in the speed of motion of a moving object, or in the direction of its motion. Motion is a vector value with both speed and direction.


How can a force effect a moving object?

It can change its speed or direction.


What changes the direction of a force?

Force changes either the speed or the direction of motion, or both.
