Answer 1

Answer:

distance - it is the length or the path taken by the object ( can be anyhow)

displacement- shortest distance between the initial and final point

speed- scalar quantity

rate of change of position with time

velocity- vector quantity

the rate of change of position wrt frame of reference

non uniform motion - moving along a path ( any shape) with different velocities

uniform circular motion - moving in a circular path with constant speed

Answer 2

Answer:

1) the amount of space between two places or things

2) In geometry and mechanics, a displacement is a vector whose length is the shortest distance from the initial to the final position of a point P undergoing motion.

3) the rate at which somebody/something moves or travels

4) the speed at which something moves in a particular direction

5) If an object is travelling with uniform motion, it is moving in a straight line at a constant speed. For example, when a car travels at a constant speed, the driving force from the engine is balanced by the resistive forces such as air resistance and frictional forces in the car's moving parts.

6) The type of motion in which the object travels with a varied speed is called Non-Uniform Motion. This means that the object does not cover the equal distance in equal time intervals. ... Non-uniform motion is also called accelerated motion.

7) Uniform circular motion, motion of a particle moving at a constant speed on a circle. In the Figure, the velocity vector v of the particle is constant in magnitude, but it changes in direction by an amount Δv while the particle moves from position B to position C, and the radius R of the circle sweeps out the angle ΔΘ.
