When an object experiences a nonzero external force, it accelerates in the direction of the force according to Newton's second law of motion (F=ma). The object's velocity changes, causing it to either speed up, slow down, or change direction depending on the direction of the force.
its velocity will change by accelerating in the direction of the force
When an object experiences a zero net force, its motion remains unchanged.
When an object experiences a negative net force, it will accelerate in the direction opposite to the force.
No, if an object has zero acceleration, its velocity cannot be changing. If the velocity is nonzero, it must either be increasing or decreasing, which requires acceleration.
An object in motion, such as a moving car or a swinging pendulum, has kinetic energy. It is the energy an object possesses due to its motion.

When a nonzero net force acts on an object, the object will accelerate in the direction of the force. The acceleration of the object is directly proportional to the net force applied and inversely proportional to the mass of the object, as described by Newton's second law of motion (F = ma).
Yes, an object can have zero velocity and nonzero acceleration. This occurs when the object is changing its direction but not its speed. For example, in circular motion, the object's velocity is constantly changing direction, leading to a nonzero acceleration even when its speed is constant.
Yes, it is possible for a nonzero net force to act on an object without changing its speed. This can happen if the force is acting perpendicular to the direction of motion, resulting in a change in direction but not speed (as in circular motion).
Newton's law of inertia: An object at rest remains at rest unless an unbalanced force acts upon it.
Velocity may change when an object experiences a change in speed or direction. This can occur when a force is applied to the object, causing it to accelerate or decelerate. Changes in velocity can also happen if an external force opposes or alters the object's motion.
An object will remain at rest until an external force is applied to it. This force could initiate motion in the object or change its state of rest.
