If the horse starts moving suddenly, the possibility of the rider falling is due to inertia. Inertia is the property of matter that resists changes in motion. When the horse accelerates forward, the rider tends to remain at rest due to their inertia. This causes the rider to lean backward or lose balance, potentially leading to a fall. This phenomenon aligns with Newton’s first law of motion, often referred to as the law of inertia. According to this law, an object at rest will remain at rest unless acted upon by an external force. In this scenario, the sudden motion of the horse acts as the external force, causing the rider to experience a change in motion. Therefore, the possibility of the rider falling when the horse starts moving suddenly can be attributed to the principle of inertia described by Newton’s first law of motion.
The working system of a rocket is based on the principle of conservation of momentum option [A]. This principle dictates that the total momentum of a system remains constant if no external forces act upon it. Rockets propel forward by expelling mass backward at high speeds, resulting in an equal andRead more
The working system of a rocket is based on the principle of conservation of momentum option [A]. This principle dictates that the total momentum of a system remains constant if no external forces act upon it. Rockets propel forward by expelling mass backward at high speeds, resulting in an equal and opposite reaction force propelling the rocket forward. This action-reaction pair demonstrates the conservation of momentum, where the momentum gained by the rocket is equal and opposite to the momentum lost by the expelled exhaust gases. This fundamental principle underlies the functionality of rocket engines and enables spacecraft to achieve propulsion in the vacuum of space where there is no air for traditional propulsion methods like jet engines. Therefore, the conservation of momentum serves as the foundational principle for the operation of rocket systems.
When a moving bus suddenly applies brakes, the passengers sitting in it fall forward. This can be explained by Newton's first law of motion, also known as the law of inertia.

When a moving bus suddenly applies brakes, the passengers sitting in it fall forward. This can be explained by Newton’s first law of motion, also known as the law of inertia. This law states that an object in motion will remain in motion with the same speed and direction unless acted upon by an external force. When the bus abruptly stops, the passengers, who were previously moving forward with the bus, continue to move forward due to their inertia. However, the bus provides the external force that abruptly halts their forward motion, causing them to fall forward. This phenomenon is commonly experienced in vehicles when sudden deceleration occurs, highlighting the fundamental principle of inertia described by Newton’s first law of motion.
The horse pulling a cart moves forward due to the force applied by the horse on the cart. When the horse exerts force on the cart through its muscles, an equal and opposite reaction force acts on the horse, causing it to move forward according to Newton's third law of motion. This force is transmittRead more
The horse pulling a cart moves forward due to the force applied by the horse on the cart. When the horse exerts force on the cart through its muscles, an equal and opposite reaction force acts on the horse, causing it to move forward according to Newton’s third law of motion. This force is transmitted through the harness or reins connecting the horse to the cart, resulting in the forward motion of the cart. Options [A], [C], and [D] are not relevant to the forward motion of the cart. While the force of gravity and contact forces between the horse’s hooves and the ground play roles in facilitating motion, they are not the primary forces responsible for the cart’s forward movement. Therefore, the correct answer is [B] By the force applied by the horse on the cart.
Newton's first law is also called the Law of Inertia. This law states that an object will remain at rest or in uniform motion unless acted upon by an external force. Inertia refers to the tendency of objects to maintain their state of motion. Options [A] Law of moment, [C] Law of energy, and [D] LawRead more
Newton’s first law is also called the Law of Inertia. This law states that an object will remain at rest or in uniform motion unless acted upon by an external force. Inertia refers to the tendency of objects to maintain their state of motion. Options [A] Law of moment, [C] Law of energy, and [D] Law of Momentum do not accurately describe Newton’s first law. While momentum and energy are important concepts in physics, they are not directly related to this law. The term “moment” is not commonly associated with Newton’s laws of motion. Therefore, the correct answer is [B] Law of Inertia, which succinctly captures the essence of Newton’s first law and its significance in understanding the behavior of objects in motion.
