Question

define 1 leration 2 distance 3 uniform motion 4 average velocity​

Answer 1

Answer: I think 1st one is acceleration

1.Acceleration- It is the rate of change of velocity

2. Distance- It is the total movement covered by any object without any regard to direction.

Uniform motion- A body is said to be in uniform motion when it covers equal distance in equal intervals of time.

Average Velocity- It is defined as total displacement divided by total time taken

Answer 2

$\huge\underline\mathfrak\orange{AnSwEr}$

Acceleration:-

• The time rate of change of velocity is called acceleration.
• Acceleration has bith magnitude and direction. Thus, it's a vector unit.
• Acceleration= $\frac{change\:in\: velocity}{Time}$
• OR, $\frac{u+v}{t}$

Distance:-

• For a particle in motion the total length of the actual path covered from the start to the end is called distance., or distance covered.
• Distance is always less than displacement.
• It is a scaler quantity,means it only has magnitude,not direction.
• It can be positive as well negetive or maybe zero.

uniform motion:-

• A uniform motion means when an object covers same distance in same interval of time with respect to the surrounding.

Average velocity:-

• Average velocity means the rate in which an object changes its position from one to another.
• Formula:- $\frac{Total~distance~covered}{Total~time~taken}$
