The mass and frequency in a vibrating system are inversely proportional to each other. When the mass is increased, the frequency decreases.... View Article
The efficiency of the pulley can increase by reducing the friction in the bearings of pulleys using lubricants. The pulleys in the lower block... View Article
An ideal pulley has no mass and no friction. The tension of an ideal cord that runs through an ideal pulley is the same on both the sides of the... View Article
The feeling of weightlessness is associated with normal force and less to do with the force of gravity. At the top of the loop, the gravity force... View Article
What happens to the voltage sensitivity of the galvanometer when the current sensitivity of a moving coil galvanometer is doubled by doubling the... View Article
London dispersion forces are the weakest of the intermolecular forces and exists between all types of molecules, whether ionic or covalent or... View Article
Gravity always acts downward on every object on Earth in the form of weight. The weight of the object is usually considered to act as a single... View Article
The force needed to move a car can be calculated using the following formula: F = ma If we know the mass of the car and the acceleration of... View Article
The electric force between q1 and q2 is directly proportional to the product of the magnitude of charge q1 and q2 and is inversely proportional... View Article
To calculate the effort required by the load, we divide the load by the number of ropes. If the person pulls a load of 500 kg using a five rope... View Article
The tension force pulling on the heavier mass M is larger than that pulling on the lighter mass m. This results in a net clockwise torque and... View Article
Force is applied to a body for a longer duration, normally more than a second. Because of which we can calculate the force and the ‘time’ it was... View Article
The Coulomb constant, the electric force constant or the electrostatic constant which is denoted by k or K is a proportionality constant in... View Article
Yes, it is possible for motion to exist without force. Issac Newton experimentally showed that bodies continue to move at a constant speed unless... View Article
If both the interacting particles are positively or negatively charged, then the force is repulsive. If both the interacting particles are of... View Article
The metre bridge is most sensitive when the four resistors forming the Wheatstone bridge are equal. This is only possible when the balance point... View Article
Consider a rod of mass M and length L. The mass per unit length of the rod is given by: s = M/L Let dx be a small part of the rod. Hence,... View Article
