Based on Newton's first Law of Motion, any (net, if two or more forces are at work) force acting on a moving object, and that, when resolved, having a component orthogonal to the direction of travel, will change the direction of the object. Simplistically, that is any force that acts on the object at an angle to the direction of motion.
Resolution of a vector (of which force is a member) involves breaking down the vector along the three orthogonal axes (x, y, and z in the Cartesian system). For the sake of convenience, one of three axes should be along the direction of travel.

What changes the direction of a force?
Force changes either the speed or the direction of motion, or both.
Can a unbalanced force change an objects motion?
An unbalanced force can: change the speed an object moves at change the direction an object is moving cause an object to start/stop moving
What are the different effects of forces on object?
force can change the shape and size of an object force can change the direction of an moving object force can make a stationary object move and make a moving object move faster force can slow down or completely stop a moving object
What can cause the direction of an object moving in a straight line to change?
An outside force.
If an object is moving at a constant speed in one direction what is needed to change its speed or direction?
An unbalanced force
What changes the direction of a force?
Force changes either the speed or the direction of motion, or both.
What determines the change in direction of an object after it collides with another moving object?
the force or other moving object
Can a unbalanced force change an objects motion?
An unbalanced force can: change the speed an object moves at change the direction an object is moving cause an object to start/stop moving
How can a force effect a moving object?
It can change its speed or direction.
What are the different effects of forces on object?
force can change the shape and size of an object force can change the direction of an moving object force can make a stationary object move and make a moving object move faster force can slow down or completely stop a moving object
Which forces change the rate and direction of an object in motion?
Any force will change the rate and/or the direction or an object, whether or not it is (initially) in motion.The only exceptions would be if there is something (like a surface supporting it) keeping the object from moving in the direction of the force, or if the object is initially not moving, and the force in not enough to overcome friction.
Would you use a balanced force or a net force to change the direction of the moving object?
net force
What can cause the direction of an object moving in a straight line to change?
An outside force.
If an object is moving at a constant speed in one direction what is needed to change its speed or direction?
An unbalanced force
Does a moving object travel in a line until a force changes its direction?
Yes. A moving object travels in a straight line at constant speed until a net force acts on it. However, the direction will only change if the force is in a different direction then the motion.
If a net force acts at an angle to the direction an object is moving the object will follow a straight curved unknown or straight forward path?
If a net force acts at an angle to the direction an object is moving, the object will follow a curved path. This is because the force causes both a change in the object's speed and its direction. The object will move in the direction of the net force, but its trajectory will be curved due to the combination of the force and the object's initial velocity.
What is necessary for a force to move an object?
No force is required to keep an object in motion. Maintaining speed and direction seems to be "the natural thing to do" for any object. A force is required to CHANGE an object's velocity, whether you want to make it go faster, slow it down, or simply change the direction for a moving object.
