I need help for my science homework:

Define speed, velocity,and acceleration

Speed is the measure of how fast an object is moving. It is the distance traveled divided by the time it took to travel that distance. Speed is a scalar quantity, meaning it only has magnitude and no direction.

Velocity, on the other hand, is the measure of how fast an object is moving in a specific direction. It is a vector quantity that includes both magnitude (speed) and direction.

Acceleration is the rate of change of velocity. It is the change in velocity divided by the time it takes for the change to occur. Acceleration can be positive (speeding up), negative (slowing down), or zero (constant speed). Similar to velocity, acceleration is a vector quantity that includes both magnitude and direction.

Which plane has the fastest speed? What made it the fastest?

The plane with the fastest speed is the "ohm airline" with a speed of 9.52 m/s. It is the fastest because it traveled the shortest distance in the least amount of time compared to the other planes. Speed is determined by the distance traveled divided by the time taken, so the plane that covers the most distance in the least amount of time will have the highest speed.
