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) ...
