Inertia is a force which brings all objects to a rest position. Fast-moving objects have more inertia than slow-moving objects. There would... View Article
Inertia is the tendency of an object to remain unchanged. Translational inertia measures the resistance offered by the object in motion when it... View Article
Which of the following has the highest moment of inertia? a) A disc about any of its diameters b) A ring about any of its diameters c) A solid... View Article
Yes, the passengers inside a vehicle obey the law of inertia. The passengers inside a vehicle are in motion with the car. Hence, if the vehicle... View Article
Law of inertia is also known as Newton's first law. The law states that “if a body is at rest or moving at a constant speed in a straight line,... View Article
Inertia is the tendency of an object to remain unchanged. The cause of Inertia is resistance. Inertia is the resistance for any moving or... View Article
The angle between the electric field and the equipotential surface is always 900. The equipotential surface is always perpendicular to the... View Article
The radius of the Earth is about 6,400 kilometres. Hence, the centre of mass for the Earth-moon system lies inside the planet which is about... View Article
Earth is a good conductor. The electrons are attracted to the sphere known as ground wire as it supplies a conducting path to the ground. The... View Article
The Pulley System makes use of a disk-shaped block that a rope wraps around to create a simple machine. A pulley helps to reverse the direction... View Article
While free-falling, gravity is the only force acting on the body. As gravity cannot be felt without any opposing force, there would be no... View Article
Newton’s second law of motion states that f = ma; the net forces (f) acting on a body of mass (m) to give it acceleration (a). If the only... View Article
The centripetal force acts perpendicular to the object path, towards the centre of the curve. Centripetal force results in the change of the... View Article
Which of the following conditions is true if enthalpy is negative and the entropy is positive? a) ?G is negative at high temperature b) ?G is... View Article
The NPN transistor is designed to pass the electrons from the emitter to the collector. The emitter “emits” electrons into the base, which... View Article
