Force and Laws of Motion Class 9 Numericals (PhysicsTeacher.in)

Today’s post is going to cover the 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 measurements of the Force and provides us the equation of force. Not only that, but we also get the idea of momentum.
The third law introduces the reaction force. So solving numerical on force and laws of motion is very important to understand the underlying theory and its real-life application.

With this introduction, we will start off listing selected numerical problems from the chapter Force and laws of motion for class 9 students.

These will not only help class 9 students to prepare their school exams but also help them to build a foundation for tougher exams in the future like IIT and other JEEs.

Force and Laws of Motion Class 9 Numericals

numerical problems in physics from force and laws of motion chapter — part 1

1> A force of 10 N is applied for 0.1 seconds on a body of mass 1 kg initially at rest. The force then ceases to act. What would be the velocity of the body just after this? After 2 more seconds, what will be its velocity?

2> A force acts for 2 seconds on a body of mass 2 kg initially at rest. Just after the force stops to act the body moves 10 m in the next 2 seconds. Find the magnitude of the force.

3> Calculate the magnitude of force which when applied on a body of mass 0.5 kg produces an acceleration of 5 m/s

4> A ball of mass 0.01 kg is moving with a velocity of 50 m/s. On applying a constant force for 2 seconds on the ball, it acquires a velocity of 70 m/s.
