Best Numericals Problems In Physics Class 9 Punjab Board Pdf Download

The Punjab Board of Education’s Class 9 Physics curriculum can provide students with the necessary tools to excel at numerical problems outlined in the Physics textbook mandated by the PTBB for educational institutions.

Numerical problems in Physics are an important part of the Class 9 curriculum for the Punjab Board. Here are some sample numerical problems in Physics for Class 9 Punjab Board:

  1. A car is moving with a velocity of 20 m/s. If it covers a distance of 100 m, what is the time taken by the car?

Solution:

We know that distance = velocity x time

Therefore, time = distance / velocity = 100 m / 20 m/s = 5 s.

  1. A ball is thrown upwards with an initial velocity of 15 m/s. Find the maximum height it will reach and the time it takes to reach there.

Solution:

We know that the maximum height reached by the ball can be calculated using the formula:

Maximum height = (Initial velocity)^2 / (2 x acceleration due to gravity)

Here, initial velocity = 15 m/s, acceleration due to gravity = 9.8 m/s^2

Therefore, Maximum height = (15 m/s)^2 / (2 x 9.8 m/s^2) = 11.47 m (approx)

To find the time taken to reach the maximum height, we use the formula:

Time taken = Initial velocity / acceleration due to gravity

Therefore, Time taken = 15 m/s / 9.8 m/s^2 = 1.53 s (approx)

  1. A body is thrown horizontally with a velocity of 10 m/s from a height of 20 m. Find the time taken by the body to reach the ground.

Solution:

We know that the time taken by a body to fall from a certain height can be calculated using the formula:

Time taken = square root of (2 x height / acceleration due to gravity)

Here, height = 20 m, acceleration due to gravity = 9.8 m/s^2

Therefore, Time taken = square root of (2 x 20 m / 9.8 m/s^2) = 2.02 s (approx)

These are just a few examples of the numerical problems in Physics that students can expect to encounter in Class 9 Punjab Board. By practicing such problems, students can strengthen their understanding of concepts, improve their problem-solving skills, and excel in the subject.
