write the difference between mass and weight distance and displacement speed and velocity uniform and nonuniform motion
please do all

There is a basic difference, because mass is the actual amount of material contained in a body and is measured in kg, gm, etc. Whereas weight is the force exerted by the gravity on that object mg. Note that mass is independent of everything but weight is different on the earth, moon, etc.
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
The short answer is that velocity is the speed with a direction, while speed does not have a direction. Speed is a scalar quantity—it is the magnitude of the velocity. Speed is measured in units of distance divided by time (e.g., miles per hour, feet per second, meters per second, etc.).
The difference between uniform and non-uniform motion can be drawn clearly on the following grounds: When an object moves along a straight line with a firm speed, the motion is said to be uniform motion. ... The object in a uniform motion covers same distances in an equal time period.
