Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.

Displacement close displacementA distance measured in a specified direction. is the distance moved in a straight line, in a given direction, from the starting point. Displacement = 24 m east. Velocity ...

Understanding the concept of acceleration, along with how to calculate it using distance and time, is fundamental in physics. Acceleration refers to the rate at which an object’s velocity changes over ...

The problems of physics are more than exercises of the intellect. Many people, including some physicists, think otherwise. In reality, physics is our second nature. The physical reality, as we ...

Long cardboard tube, such as an empty roll of wrapping paper, to make your ramp. It should be at least two-and-one-half feet long. A thin book or small wood block to raise one end of your ramp. It ...

Abstract: An approach is proposed to estimate the location, velocity, and acceleration of a target vehicle to avoid a possible collision. Radial distance, velocity, and acceleration are extracted from ...
