If we are standing in a bus and the driver applies a brake then we feel:
Correct answer: B. A pseudo force pushes forwards
- A. A pseudo force pushes backwards
- B. A pseudo force pushes forwards
- C. A real force pushes backwards
- D. A real force pushes forwards
Explanation
A pseudo force (also called a fictitious force, inertial force, or d'Alembert force) is an apparent force that acts on all masses whose motion is described using a non-inertial frame of reference, such as a rotating reference frame. Pseudo force comes into effect when the frame of reference has started acceleration compared to a non-accelerating frame.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
