Velocity refers to the rate at which an object changes its position in a specific direction. It includes both speed and direction.
Imagine you are driving a car on a straight road. Your velocity would be your speedometer reading combined with whether you are going forward or backward, left or right.
Speed: Speed measures how fast an object moves without considering its direction. Unlike velocity, it does not take into account if the object is moving forward, backward, etc.
Acceleration: Acceleration describes how quickly an object's velocity changes over time. It can refer to speeding up, slowing down, or changing direction.
Displacement: Displacement measures the change in position from one point to another for an object moving in a specific direction. It considers both distance and direction.
