Priyanka B Solutions for Chapter: Motion, Exercise 5: Assignment

Give an example of retardation or negative acceleration.

Define uniform acceleration.

What is the acceleration of a body moving with uniform velocity?

What do we mean by saying that acceleration of a body is $5 \raisebox{1ex}{$\mathrm{m}$}\!\left/ \!\raisebox{-1ex}{${\mathrm{s}}^2$}\right.$?

A car starts with a velocity of $10 \raisebox{1ex}{$\mathrm{m}$}\!\left/ \!\raisebox{-1ex}{$\mathrm{s}$}\right.$ and accelerates at a rate of $5 \raisebox{1ex}{$\mathrm{m}$}\!\left/ \!\raisebox{-1ex}{${\mathrm{s}}^2$}\right.$. Find the final velocity when the car has travelled a distance of $30 \mathrm{m}$.

State the three equations of motion. Which of them describes a velocity-time relation?

State the three equations of motion. Which of them describes a position-time relation?

Derive the equation $v^2-u^2=2as$.
