Have you ever felt a sudden jolt when a car accelerates or brakes abruptly? It almost seems like an invisible force is pulling or pushing you. That’s the effect of what scientists call Pseudo Force or Fictitious Force.
What is Pseudo Force?
Pseudo force is not a real force but an apparent force experienced when observing motion from a non-inertial reference frame — like a moving vehicle. When you are inside an accelerating or decelerating vehicle, you feel as though a force is acting on you, even though no physical force is being applied. This phenomenon is a result of applying Newton’s laws in an accelerating frame of reference.
For example, when a truck accelerates forward, a bob hanging from the roof swings backward. To an observer standing outside the truck (an inertial frame), the bob stays in place due to inertia while the truck moves forward. But to someone inside the truck, it seems like an invisible force is pulling the bob backward — this is the pseudo force.
Real-Life Examples of Pseudo Force
You experience pseudo force in daily life without realizing it. Some common examples include:
- When a bus takes a sharp turn, you feel pushed to one side.
- In an elevator that suddenly moves up or down, you feel heavier or lighter.
- On a spinning merry-go-round, you feel thrown outward (known as centrifugal pseudo force).
Understanding pseudo force is essential to learning motion in non-inertial frames of reference and is a key concept in mechanics.
Experience Pseudo Force Experiment Virtually with Dencity
Setting up a real-life pseudo force experiment in a traditional physics lab is impractical, costly, and risky. This is where the Dencity Virtual Science app becomes a revolutionary tool.
Bob Hinged in a Moving Vehicle (Pseudo Force) Experiment
In Dencity’s interactive virtual experiment, students can simulate a moving truck with a bob hanging inside it. They can control the truck’s acceleration and deceleration using pedals in the app and observe the bob swinging backward or forward in real time. This hands-on virtual experience helps students understand the concept visually and interactively.
Why Use Dencity for Pseudo Force Experiments?
- Affordable and Safe: No need for real vehicles or expensive setups.
- Accessible: Available anytime, anywhere.
- Interactive: Real-time simulation with acceleration controls.
- Conceptual Clarity: Students can visually understand pseudo force and its effects.
- Class 11 & 12 Science Students: Specifically designed to align with the curriculum.
Dencity for Teachers: Elevate Interactive Teaching
Dencity is not just a learning tool for students but also a powerful teaching resource. Teachers can:
- Create virtual classrooms and conduct live sessions.
- Assign the Pseudo Force Experiment as homework and monitor student progress.
- Explain complex concepts visually in real time.
- Promote interactive learning by letting students control simulations during class.
By integrating Dencity, teachers can transform their classrooms from traditional chalk-and-talk methods to engaging, practical, and interactive sessions.
Dencity on Interactive Touch Panels
Dencity works seamlessly on interactive touch panels widely used in modern classrooms. Teachers and students can collaborate and perform experiments on big screens, making learning more engaging and effective. The Dencity app is available across platforms — Android, iOS, and Desktop — allowing schools to set up a virtual physics lab without needing physical infrastructure or maintenance.

Frequently Asked Questions (FAQs)
Q1: What is pseudo force?
Pseudo force is an apparent force experienced in a non-inertial frame of reference, such as a moving vehicle. It is not a real force but seems to act on objects due to the acceleration of the reference frame.
Q2: Why do we feel a jerk when a vehicle starts or stops suddenly?
This is due to pseudo force. When a vehicle accelerates or decelerates, your body tends to remain in its original state of motion, making you feel a push or pull.
Q3: What is the real-world application of pseudo force?
Pseudo force is crucial in understanding motion in non-inertial frames, such as vehicles, elevators, and rotating systems like merry-go-rounds.
Q4: How can I perform a pseudo force experiment without a physical lab?
You can use the Dencity virtual lab to perform the Pseudo Force Experiment safely and interactively.
Q5: Is the pseudo force experiment available for all classes?
This experiment is designed primarily for class 11 science and class 12 science students.
Q6: What devices support Dencity?
