The correct answer is (c) Is least on equator. The acceleration due to gravity (g) is slightly less at the equator and greater at the poles due to Earth’s rotation and its slightly oblate shape. Centrifugal force at the equator ...

The correct answer is (c) Force acting on the object due to force of gravity. Weight is the gravitational force exerted on an object by Earth. It is given by W = mg, where m is mass and g is ...
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 ...
Inertia is the tendency of an object to resist any change in its state of motion (whether at rest or in motion), as described by Newton’s first law of motion. Thus, the correct answer is:(c) to resist any change in ...
(a) Its speed keeps changing → because acceleration means a change in speed or direction. (b) Its velocity keeps changing → since acceleration affects velocity. (c) It always goes away from the Earth → an object can accelerate in any ...
Newton’s second law of motion states that the force acting on an object is equal to the product of its mass and acceleration (F = ma). This law helps to determine the magnitude of force, making the correct answer: (a) ...
