First, let me comment that your printing is neat and readable in the image. However, you are much more likely to get responses to your questions if you type in your solution. Many helpers will not respond otherwise.Alexanddros81 said:
Motion is the change in position of an object over time. It can be described using variables such as displacement, velocity, and acceleration.
A particle is a small, localized object that can be treated as a single point in space. It has mass and can undergo motion.
Zero velocity, also known as rest or stationary, means that the particle is not moving. Its displacement remains constant over time.
Yes, a particle can have zero velocity and still be in motion. This is known as uniform motion or constant velocity. In this case, the particle is moving at a constant speed in a straight line.
Zero velocity means that the particle is not moving, whereas zero acceleration means that the particle's velocity is not changing. This means that the particle may be moving at a constant speed, but its direction may be changing.
