One Dimensional Equations of motion (constant acceleration) Practice Problems
One Dimensional Equations of motion (constant acceleration) Practice Problems
In this lecture , we solve the equation of motion numericals of the type one-dimensional / constant acceleration. We start with tricks/cautions on how to tackle equations of motion; then we solve a few easy problems; and finally we solve a three stage monster in the end ! This is an excellent lecture for you to practice with as it has theory and level of problems is varied.
It is useful for all boards - CBSE / ICSE / IGCSE.
Attached herewith are Equations of Motion practice sheet.
A bored Galileo and Einsten's Fanboy moment !
Galileo is to pendulum as Gabbar is to Sholay ! No talk about penduluum is complete without Galileo's name. Legend is that a bored Galileo got interested in pendulums while he he was in a church in Pisa and noticed a lamp swinging back and forth overhead. He observed that the lamp repeated the same pattern of swing Einstein was Galileo’s biggest fan and called him the father of modern physics.
I find Foucault pendulum intriguing.

Practice Test for Rotational Motion
Q1. Derive an expression for Kinetic energy of rotating body with uniform angular velocity
Q2.Obtain an expression for torque acting on a rotating body with constant angular acceleration
Q3. Deduce an expression for kinetic energy when a body is rolling on a plane surface without slipping
Q4. Define angular momentum of a body obtain an expression for angular momentum of a rigid body rotating with uniform angular velocity. State its SI unit and dimensions
Q5. State and prove principle of conservation of angular momentum. Explain it with examples
Q6. What will be the duration of the day if the earth suddenly springs to 1/27th of its original volume; mass being same.
Q7. A wheel of moment of inertia 1 kg metre square is rotating at a speed of 30 Radian per second. Due to friction on the axis, it comes to rest in 10 minutes. Calculate
i total work done by the friction
ii the average torque of the friction
iii angular momentum of the wheel 2 minutes before it stops rotating
