The formula for finding the speed of a particle is speed = distance/time.
The distance traveled by a particle can be calculated by multiplying the speed by the time it traveled.
The unit of measurement for speed is typically meters per second (m/s).
Yes, the speed of a particle can change over time. This can occur if the particle is accelerating or decelerating.
The initial velocity of a particle will play a role in determining its speed after 0.2 seconds. If the particle is already moving at a certain speed, it will continue at that speed unless acted upon by an external force. If the particle is starting from rest, it will accelerate and its speed after 0.2 seconds will be determined by its acceleration rate.
