Thrust is a force that propels an object forward or upward by expelling gas or fluid in the opposite direction. It can increase the speed of an object if the net force of thrust is greater than the opposing forces like drag or gravity acting on the object.
Friction acts to slow down the motion of an object. It opposes the relative motion between two contacting surfaces, reducing the speed of the object in motion.
A force that is perpendicular to the direction of motion of the object will never speed it up. This is because the force is unable to transfer any of its energy in the direction of motion.
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.
Friction always opposes motion, so it can never speed up an object. Friction slows down or stops an object's motion by acting in the opposite direction. To speed up an object, a force stronger than friction, like a push or a pull, is needed.
No. This is because the object is speeding up, therefore more force must be acting on one side than on the other. However, if the object was moving at a constant speed or was stationary, then the forces would be balanced.

When the forces on an object add up to zero, the object's acceleration is zero. Thatmeans the speed or direction of its motion doesn't change. It does not mean thatthe object isn't moving. A moving object would just keep moving at a constantspeed in a straight line.

Friction does not speed up an object; it creates drag and slows it down.
An unbalanced force will always cause a change in the motion of an object. This change can involve speeding up, slowing down, changing direction, or a combination of these. Inertia, the tendency of an object to resist changes in its motion, is overcome by the unbalanced force, leading to the change in motion.
It can change the direction of motion or it can speed up or slow down an object.
Force can change the speed, direction, or shape of an object's motion. It can cause an object to speed up, slow down, or change its path of motion. Force can also cause an object to deform or break depending on its magnitude and direction.
The effect of a push or pull on an object's motion is that it causes the object to accelerate in the direction of the force applied. This acceleration can either speed up, slow down, or change the direction of the object's motion.
