An aircraft is moving with a velocity of 300ms-1. If all the forces acting on it are balanced, then
Correct answer: A. It still moves with the same velocity
- A. It still moves with the same velocity
- B. It will explode
- C. It will lose its velocity gradually
- D. It will fail down instantaneously
Explanation
A is correct, if forces on both the sides are balanced then the aircraft will move with same velocity.

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.
