Basics of Dynamics

Define the term non-uniform velocity.

The average _____ of a moving particle can never be zero.

The earth is moving with a uniform speed and a non-uniform velocity.

Is it possible for a body to have a uniform speed and non-uniform velocity at the same time?

Define non-uniform velocity.

If the speed or _____ changes then the body is said to have a non-uniform velocity.

How non-uniform velocity is different from uniform velocity?

If an object is travelling $15 \mathrm{m}$ from $\mathrm{A}$ to $\mathrm{B}$ with a uniform velocity of $10 \mathrm{m} {\mathrm{s}}^{-1}$ in $5 \mathrm{mins}$ then what will be the acceleration of the object.

The light travelling through vacuum is an example of _____ velocity.

What is the difference between uniform speed and uniform velocity?

Why rest and motion are called relative terms?

Suppose a boy is enjoying a ride on a merry-go-round which is moving at a constant speed of $6 \mathrm{m} {\mathrm{s}}^{-1}$. It implies that the boy is

Which of the following is true for displacement?

A) It cannot be zero.

B) Its magnitude is greater than the distance travelled by the object.

C) It is the shortest distance between the initial and final position.

D) It is a vector quantity.

An object covers a distance of $5 \mathrm{m}$ from point $\mathrm{A}$ to $\mathrm{B}$ and then comes back from $\mathrm{B}$ to $\mathrm{A}$. What is the total displacement of the object?

A car starts from rest and achieves a speed of $54 {\mathrm{kmh}}^{-1}$in $3$ seconds. Find its acceleration?

When will you say a body is in the uniform acceleration?

Weight of an object can be explained as                                                                         

The sound from the volcano was heard $4780 \mathrm{km}$ away. If the speed of sound is $330 \mathrm{m} {\mathrm{s}}^{-1}$, how long would it have taken the sound to travel this distance?

The study of motion without regard to forces that cause it is known as
