Force is an influence on something to change its speed, direction or shape. Like pulling or pushing, your are changing its speed and possibly its direction. Or gravity, it always directs you back to earth.
Just guessing here because I'm not a scientist, however, I'm guessing force moves thing because of energy. Things need kinetic energy to move, therefore force must give an object kinetic energy. Like when you push something, you are transferring kinetic energy from your body into an object which then moves.
Hope that helped, though I could be wrong, I have no evidence or experience to back any of that up with.

Force is a push or pull acting on an object that can cause it to move, stop, or change direction. When a force is applied to an object, it can accelerate (increase its speed), decelerate (decrease its speed), or change direction depending on the size and direction of the force. According to Newton's laws of motion, a force is directly proportional to the acceleration of an object and inversely proportional to its mass.

What is Any part of force that does not act in the direction of an objects motion does not?
Any part of a force that does not act in the direction of an object's motion does not contribute to the object's speed or change its velocity. This component of force perpendicular to the direction of motion only affects the object's direction or causes it to change its path.
What does a force always act on?
A force always acts on an object to cause a change in its motion or position.
What must happen for an object that is already moving to change its speed or direction?
For an object to change its speed or direction, a force must be applied to it. The magnitude and direction of the force will determine how the object's speed or direction changes. This change in motion is described by Newton's laws of motion.
How can forces act on an object without causing a change in the objects motion?
Forces can act on an object without causing a change in the object's motion if the forces are balanced. When the total force acting on an object is zero, the object will either remain at rest or continue moving at a constant velocity, according to Newton's first law of motion.
What determines whether an object's motion will change?
An object's motion will change if an external force is applied to it. The magnitude and direction of the force, as well as the mass of the object, will determine how much the object's motion will change. According to Newton's second law of motion, the acceleration of an object is directly proportional to the force applied and inversely proportional to the mass of the object.
What is Any part of force that does not act in the direction of an objects motion does not?
Any part of a force that does not act in the direction of an object's motion does not contribute to the object's speed or change its velocity. This component of force perpendicular to the direction of motion only affects the object's direction or causes it to change its path.
What does a force always act on?
A force always acts on an object to cause a change in its motion or position.
A force is needed to change the motion of an object?
Yes, an unbalanced force is needed to change the motion of an object.If an unbalanced force does not act on an object it will continue to maintain its state of motion (either in motion or at rest), not considering the effect of frictional force. This is basically Newtons first law of motion.
What is needed in order to cause an object at rest to or an object in motion to change its direction or speed?
An outside force to act on it
What kinds of forces can act on an object?
Normal force can act on an object

What is needed in order to cause an object at rest to move or an object in motion to change its directed or speed?

What happens when a force act on an object?
When a force acts on an object, it can cause the object to accelerate, decelerate, or change direction. The object's motion is determined by the magnitude and direction of the force applied to it, in accordance with Newton's second law of motion.

What has to act on an object for it to stay in motion?
An external force must act on an object for it to remain in motion. According to Newton's first law of motion, an object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an external force.
