As we move from the equator towards the poles, the value of g decreases. This is because the centrifugal force due to Earth’s rotation is greatest at the equator, causing a slight outward push that counteracts some of the gravitational ...

When a person lands on the Moon, there is a change in weight. Weight is the force exerted on an object due to gravity, and since the Moon has less gravity than Earth, the person’s weight decreases. However, their mass ...
Force is the product of mass and acceleration. It is described by Newton’s second law, F = ma, where F represents force, m is mass, and a is acceleration. This relationship states that the force acting on an object is ...
A cricket player catches a fast-moving ball by pulling his hand back because it may require applying less force. This technique allows for better control, reduces the impact force, and minimizes the chance of injury or the ball bouncing off ...
A person trapped in a swamp is advised to lie down because as the area increases, the pressure decreases. Distributing the weight over a larger surface area reduces the pressure exerted on the swamp’s surface, making it less likely to ...
The working system of a rocket is based on the principle of conservation of momentum. This principle states that the total momentum of a system remains constant if no external forces act upon it, which enables rockets to propel forward ...
The horse pulling a cart moves forward due to the force applied by the horse on the cart. This force, exerted by the horse’s muscles, propels the cart forward as a reaction to the force exerted by the horse.
Newton’s first law is also called the Law of Inertia. It states that an object will remain at rest or in uniform motion unless acted upon by an external force. This law lays the foundation for understanding the concept of ...
According to Newton’s third law of motion, the forces related to action and reaction can be applied on different objects. This law states that for every action, there is an equal and opposite reaction, which means the forces act on ...
The acceleration produced in a body by an unbalanced force is directly proportional to the force. This relationship is described by Newton’s second law of motion, which states that acceleration is directly proportional to the force applied and inversely proportional ...
