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.

A force applied perpendicular to the direction of motion can change the direction of a moving object. This force causes the object to change its path without necessarily altering its speed.
Yes, an unbalanced force can change an object's motion by causing it to accelerate or decelerate in the direction of the force. It can also change the object's direction or speed depending on the magnitude and direction of the force applied.
To change the direction that an object is moving, you will need to apply a force in the opposite direction to the object's current motion. This force can be applied by pushing or pulling the object or by using external forces such as friction or gravity to alter its trajectory. By adjusting the magnitude and direction of the force, you can change the object's movement.
The result of a force acting on a moving object over time is a change in the object's velocity. This change can be an increase or decrease in speed, a change in direction, or both, depending on the magnitude and direction of the force.
When an unbalanced force is applied to a moving object, the object will experience acceleration in the direction of the force. If the force is in the same direction as the object's motion, it will speed up. If the force is in the opposite direction, it will slow down or change direction.
The direction of a force changes when another force acts in the opposite direction to oppose it, or when the object experiencing the force changes its own direction of motion.
