An object’s speed is how far that object has gone in a given time.

Typical Speeds

Velocity is speed in a given direction. Acceleration is a change in velocity.

In Physics, mass and weight are not the same thing! Weight is a force - mass is not.

The density of an object is how much mass is packed into one unit of volume.

Pressure is the force applied per unit area.

You can organise basic quantities of physics into two types of quantities: Scalars and Vectors.
