An object in motion.
If there are no outside forces acting on a system of particles the total momentum of the system will remain constant; i.e. the center of mass of the system will remain at rest or move at constant velocity.
If no unbalanced forces act on an object at rest, it will remain at rest due to Newton's first law of motion, which states that an object will stay at rest or in motion with a constant velocity unless acted upon by an unbalanced force.
The tendency of an object to remain at rest or in motion with a constant velocity is known as inertia.
The velocity of an object will increase as it falls towards the ground due to the acceleration of gravity. However, once it reaches terminal velocity, its velocity will remain constant.
No, if the instantaneous velocity of an object remains constant, then its instantaneous speed cannot change. Velocity is a vector quantity that includes both speed and direction. If the velocity is constant, it means both the speed and direction are constant.
Yes. An unbalanced force is needed to change the direction of an object's motion. This is an example of Newton's first law of motion which states that a body at rest will remain at rest and a body in motion will remain in motion in a straight line at constant velocity unless acted upon by an unbalanced force. Constant velocity means the same speed and direction. So if the direction changes, so does the velocity.

Newton's First Law of Motion states that an object remains at a constant velocity unless it has an unbalanced force acting upon it. That constant velocity includes zero, which means that a stationary object with no force applied to it will not move. Since velocity includes direction, then a moving object with no force applied to it will continue to move in a straight line at a constant speed.That tendency is called inertia.
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).
The magnitude of the velocity will be constant however the direction will be constantly changing. The acceleration will remain constant towards the centre of the circle
An object at rest will remain at rest, and an object in motion will continue to move with a constant velocity in a straight line if no unbalanced forces act on it, according to Newton's First Law of Motion.
