Questions

1. If a = 2t + 1, find the average velocity.

2. If a = 2t^2 + 1, find average acceleration between t=1 sec to t =3 sec.

3. A car is moving with a velocity of 25 m/s. It undergoes a retardation of a = -2$\sqrt{v}$. Find the time at which it comes to rest.

Quick Overview

1. General Common Sense Qs

2. Distance vs Displacement

3. Speed

   • Uniform Speed

   • Non-uniform Speed

   • Instantaneous Speed → Measured by Speedometer

   • Average Speed

     • for equal distances

     • for equal time

   • Instantaneous Velocity

     • It's differentiatable nature

   • Average Velocity

     • for equal distances

     • for equal time

     • between two points

5. Acceleration

   • Uniform Acceleration

   • Non-uniform Acceleration

   • Instantaneous Acceleration → It's differentiatable nature

   • Average Acceleration

     • between two points

6. Graphs
