how to solve motion problems physics linear motion

Comparison of Linear and Rotational Motion - When a rigid body such as a merry-go-round rotates around an axis, each particle in the body moves in its own circle around that axis. Since the body is rigid, all particles make one revolution in the same amount of time. i.e., they a..

When a rigid body such as a merry-go-round rotates around an axis, each particle in the body moves in its own circle around that axis. Since the body is rigid, all particles make one revolution in the same amount of time. i.e., they all have the same angular speed w..

As the initial velocity, final velocity, distance travelled, acceleration and time are related and are expressed as equations of motion in linear motion; one can derive equations for rotational motion also. If w 0 is the initial angular velocity of a rotating..

Momentum Conservation and Motion of Centre of Mass - As we know, the linear momentum of a particle is defined as , where m is the mass and is the velocity, the momentum of an N particle system is the vector sum of the momenta of the N particles. If the external forces acting on ..

Summary - The centre of mass is an imaginary point where one can assume the entire mass of the given system or object to be positioned. Principle of conservation of linear momentum states that the linear momentum of a system remains constant if the external forces acting on the ..

The process of producing electricity by magnetic field is called electromagnetic induction. Electric current can also be induced through a wire loop, by moving it near a fixed magnet. So a current is induced either by moving a magnet near the loop or by moving the loop near a magnet. It is the rela..

Comparison between Progressive Waves and Stationary Waves - Progressive waves Stationary waves The disturbance produced in the medium travels onward, it being handed over from one particle to the next. Each particle executes the same type of vibration as the preceding one, though not at the same ti..

Next, consider how the position vector changes with time in the case of uniformly accelerated motion. The average velocity in the time interval from t to is given ..

and d is the distance between the two coherent sources. When a source gives white light, interference fringes are colored. Red fringes are wider as l r is large. Coherent sources are those, which emit continuous light waves of same amplitude, same wavelength/frequency in the same phase or having a ..

In the physical world, one of the most common phenomena is motion. The branch of Physics, which deals with the behaviour of moving objects, is known as mechanics. Mechanics is further divided into two sections namely Kinematics and Dynamics. Kinematics deals with..
