all external forces can change the velocity of a body
e.g.(gravity,friction etc.)
Yes, that is correct.
Forces that are equal in magnitude, opposite in direction and acting on the same object will not create a change in said objects motion.

If I am reading your question correctly, you want to now if balanced forces can change the direction an object is traveling. The answer is no. Balanced forces always produce no net change, hence the term "balanced". You need an unbalanced force to change the direction of an object, or to set an object in motion from a standstill.
If the forces on an object are unbalanced then the objects motion will change. It will start accelerating in the direction of the resultant force. Only objects that have balanced forces will remain in the same motion (stationary or moving at a constant speed).
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
If the force is acting in the opposite direction to the movement, the object will slow down and then accelerate in the direction of the force. Negative for
In the activity, I recognized the force of gravity acting downwards on the objects, the force of tension in the strings holding the objects, and the forces of friction between the objects and the surfaces they were placed on.
if the force isnt inline , resolve into axial and lateral forces, the original force bieng the hypotonuse

Gravity is one of the forces
