Physics Problems

Physics Problems is an excellent
online study resource for students. It is an exhaustive collection of solved
examples and answers for physics problems and questions.

Students can get online tutors who
can help them understand the concepts and the logic behind the answers for Physics
. They can also get help with their homework problems in physics
and other assignment questions related to Physics. The online physics tutors
are expert in their subjects who can help the students  in solving all
their queries. One can also get physics homework help from our tutors.

Physics problems cover all the
important topics under physics for various grades. The students can get
grade-specific help with their physics problems. The students can learn by
observing the solved examples. They can understand the concepts step by step,
therefore, they would be able to solve physics problems on their own. They can
even learn about the topics in depth and practice problems on physics which in
turn will help them to prepare for their exams.


Problems and Solutions

Physics questions and answers are an
entire list of solved problems and questions about physics concepts. The
students can get the list of frequently asked questions of various physics
topics. The following are some physics topics which are covered under the
physics problems:

Classroom Examples

Here are some physics classroom
examples for students:


Question 1: A car moving with a velocity of 18 kmph is brought to rest
in a distance of 0.5 km by applying brakes. Find its retardation?

Initial Velocity of the car = u = 18 kmph = 5 ms-1,
Final Velocity of the car = v = 0,
Distance travelled = S = 0.5 km = 500m
We have, v2 = u2 + 2as.
             0 = 52
+ 2

a ×
25 + 1000a.
          -25 = 1000a,
             a = -0.025 ms-2.

Retardation of the car = 0.025ms-2.

Question 2: A Heat engine operates with reservoir temperature between
900 K and 500 K. Calculate its efficiency?

T1 = 900 K,
T2 = 500 K,

= 1 – T2T1
= 1 –

= 0.46.
Hence the efficiency of the engine is 46%.
