Contact forces: types of forces that result when the two interacting objects are apparent to be physically linking each other.
Ex: frictional forces, tensional forces, normal forces, air resistant forces, applied forces.
Lagrange points: Points within the vicinity of two massive bodies (like the Earth and the Moon) where each others' respective gravities balance. There are five, labeled L1 to
Two forces-55-N clockwise and 35-N counters clockwise-are applied to a merry- go-round with a diameter of 4.5 m. What is the net torque?
in which case there is change in acceleration in case of pulley?
Electrical work: Electrical work is done if a quantity of charge (coulombs) is moved between two points which are at different electrical potentials. The SI unit of work
IMPULSE: When a force acts on a body for a very short time, the product of the force and the time for which the force acts, is called the impulse or impulse of force".
Q Define threshold frequency? The minimum frequency of incident radiation lower which the photoelectric emission isn't possible completely but high the intensity of incident r
It states that angular momentum of a system remains conserved if no net torque is acting on the system.
