The correct answer is (b) Force. Newton’s Second Law states that force (F) is the product of mass (m) and acceleration (a), given by F = ma. This law quantitatively defines force, showing how it depends on an object’s mass ...

The correct answer is (d) Inertia. Newton’s First Law of Motion states that an object remains at rest or in uniform motion unless acted upon by an external force. This property of resisting changes in motion is called inertia, making ...
The correct answer is (c) directional inertia. When the bus suddenly turns, passengers tend to continue moving in their original direction due to inertia. This resistance to a change in direction is called directional inertia, which causes them to be ...
The correct answer is (b) 0 N. Since the table is frictionless and the object is already moving with a constant velocity of 4 m/s, no external force is required to maintain its motion. According to Newton’s First Law, an ...
The correct answer is (a) Accelerated. When the passenger tosses the coin, it retains the train’s initial velocity. However, if the train is accelerating, the passenger moves forward with increasing speed while the coin lags behind, appearing to fall backward ...
