Distance: Distance is the length between two points, you can also use feet to mesure the distance.

Direction is the may where motion goes, a vector is a line and a arrow to show direction

Speed is a continious motion that is divided by distance and time. Instintanuas speed is either faster or slower.

Velocity is speed and distance so you could be going 45mph and turn right. Average velocity is speed but same direction.

The first thing of acceleration is a change of velocity. it can change the speed or direction in velocity.

The second thing of acceleration is that it can be positive or negative,so a car can go fast and then slow at a curve.

The final thing about acceleration is that you can feel it. If you are in a car and then go slow you feel acceleration.
