1. Constant Displacement: The object covers equal distances in equal time intervals. This means its position changes uniformly over time.
2. No Acceleration: Since the speed is constant, the object's velocity doesn't change. This implies that there is no acceleration, meaning no change in speed or direction.
3. Zero Net Force: According to Newton's First Law of Motion, an object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by a net force. This means that for an object moving at a steady speed, the net force acting on it is zero.
4. No Change in Kinetic Energy: Kinetic energy is the energy of motion. Since the speed is constant, the kinetic energy of the object remains constant.
5. Predictable Path: The object's movement follows a predictable path. If the object moves in a straight line, its path is linear. If it moves in a circle, its path is circular.
Examples:
* A car driving down a highway at a constant 60 mph.
* A plane flying at a constant altitude and speed.
* A ball rolling across a smooth surface at a constant speed.
Note: It's important to distinguish between speed and velocity. Speed is the rate of movement, while velocity is the rate of movement in a specific direction. While an object can move at a steady speed, it can still change direction, meaning its velocity would change, and therefore it wouldn't be at constant velocity.
