Yes, it can move in a curve.
An object that is accelerating is either speeding up or slowing down. If the acceleration is in the same direction as the velocity, the object is speeding up. If the acceleration is opposite to the velocity, the object is slowing down.
An object with uniform motion has a constant speed and direction. This means it travels at the same velocity without speeding up or slowing down.
When an object is speeding up or slowing down, it is experiencing acceleration. When it is turning, it is undergoing rotation or changing direction.
When we say an object moves with constant speed, it means that the object is moving at the same rate without speeding up or slowing down.
Take the component of the acceleration along the direction the object is moving. If this component is positive (the acceleration vector, or the relevant component, points in the same direction as the movement), then the object is speeding up.

When it is stationary, or when the velocity is constant. If it is speeding up or slowing down, it has acceleration.
The object is experiencing acceleration when it is speeding up or slowing down, and turning is an example of angular acceleration. Acceleration is the rate of change of velocity, either in speed or direction.
When an object's velocity remains constant, it means the speed and direction of the object's motion do not change. This implies that the object is moving at a consistent rate without speeding up, slowing down, or changing course.
A constant speed is a speed that doesn't change over time. This means that an object is moving at the same rate without speeding up or slowing down.
An object that is neither speeding up nor slowing down travels at a constant velocity. This means its speed remains the same over time, covering equal distances in equal intervals.
Acceleration refers to the rate of change of an object's velocity, which can include both speeding up and slowing down. When an object accelerates, it can increase or decrease its speed depending on whether the acceleration is in the same direction as the velocity (speeding up) or in the opposite direction (slowing down).
Imagine an object traveling a circle at constant speed, but according to Newton's First Law, an object moving in a straight line will continue to move in the straight line at constant speed unless acted upon an external net force not equals to zero. Hence, it can be concluded that the object is acted upon by an external force since it is not moving in a straight line, with the net force directed at the center of the circle and similarly for the acceleration, although it may be still traveling at the same speed (note: it's speed not velocity!)
