force can speed up, slow down, and/or change direction of an object commonly refered to as acceleration
A moving body can be accelerated by applying a force. This force will act to increase velocity, decrease velocity or change the direction the body is moving. All three of these are acceleration.
Making an object speed up or slow down always requires a force.-- To make the object speed up, apply a force to it in the same directionthat it's moving.-- To make it slow down, apply a force to it in the opposite direction.
As Newton's laws state, the greater the force, the more an object will accelerate or slow down. The force in the opposite direction of motion is called friction. So if you have a 3Kg block travelling at 2m/s, with a friction of 1m/s you will need at least 5N to keep it going. The more force you apply, the faster the block will travel, so it accelerates. The less force you apply the more it slows down and eventually stops because the friction is greater than the force applied. An object that travels in a uniform direction at a uniform speed (Newtons 1st law) will continue traveling in the same way and in the same direction (inertia) unless acted upon by a resultant force (friction).
That could be one description of "force" or "net force."Notice that it can also change the direction in which an object is moving,without changing its speed at all.
An object acted on by a force will accelerate in the direction of the force. Be careful, though, as this doesn't mean it will actually MOVE in the direction of the force. It may just slow down, etc.
The motion of an object will change when it is acted on by some force. This force will speed it up, slow it down, change its direction of motion or perhaps cause it to spin. All thses changes of motion are response to the force acting on the object. This is Newton's first law: An object in motion will continue in motion (and in the same direction) unless acted on by some force. Some might call this the law of inertia.

The object will speed up, slow down or change direction. An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. ... If however, the forces are balanced (in equilibrium) and there is no net force, the object will not accelerate and the velocity will remain constant.
it could speed up or slow down, it depends which force is bigger and which direction the force is pushing/pulling etc.
You will travel in the same direction, at the same speed for eternity unless your vehicle is acted upon by some other force such as gravity or an atmosphere (Newton's Second Law). There is no air in space, and therefore no friction to slow the vehicle down and without fuel, you cannot change the direction.

An object falling at terminal velocity is moving at constant speed (that's what terminal velocity means) and we will assume it is not changing direction (i.e. it is falling straight down; in reality it is more likely to be bobbing and weaving on the wind.) Constant speed and direction is another way of saying constant velocity. when an object is acted upon by a net force, it's velocity changes. So, since we know that the velocity is not changing, there is no force.
It doesn't. For example, you can go in a straight line, and speed up or slow down, without changing direction. And if there is both a change in direction and a change in speed, the change of speed wouldn't be the CAUSE for a change in direction. (On the other hand, both can be caused by a force applied to an object.)
An object can only slow down, speed up, or change direction, if there is a net force acting on the object.
