Todays post is going to cover Force and Laws of Motion Class 9 Numericals. Newton’s Laws of motion and Force are tightly coupled. The first law gives us the concept of force and its effect on inertia. The second law gives us more concrete measurement of the Force and provides us the equation of force.
In this post we will solve harder numerical problems on Vertical motion physics. vertical motion is an interesting chapter in mechanics . Here you get selected problems to solve which will help you to test your understanding.
49) A hammer exerts a force of 1·5 N on each of the two nails A and B. The area of cross section of tip of nail A is 2 mm^2 while that of nail B is 6 mm^2. Calculate pressure on each nail in pascal. Solution Nail A Force F = 1.5 N Area
solution of 5 numericals from Q set 1 for class 9. Motion under gravity is the primary focus of the following problems. Upward and downward movement, maximum height reached, time to reach the maximum height, velocity just before touching the ground etc are the touched upon points of these sort of numerical problems in physics.
