Inertia: the resistance an object has to a alter in its state of motion.
Newton's first law of motion declares that force is NOT required to keep an object in motion.
Slide a book across the table and watch it slide to a rest position. The book in motion on the tabletop does not come to a rest position due to the absence of a force; rather it is the presence of a force - the force of friction - that brings the book to a rest position.
a body travelling with uniform acceleration crosses two points A &B with velocities 30m/s & 50m/s the speed of the body at mid point of A&B is approximately?
Two Stage Rocket Suppose the motion of the two-stage rocket or the corresponding velocity-time graph below. The rocket has two successive fuel stages followed through a free-fa
A block of mass m is tied to a cord of length L that is pivoted at the center of a frictionless table. A second block of mass m is tied to the ?rst block also on a cord of length L
how can we conclude whether at some time interference will take place or not with the help of the concept of temporal coherence?
what is newton first law of motion
An ore sample weighs 17.50 N in air. When the sample is suspended by a light cord and totally immersed in water, the tension in the cord is 11.20 N. Find the total volume and the d
If the distance between the earth and moon were halved, the force of the attraction between them would be: a) One fourth as great b) One half as great c) Twice as g
Transition temperature It is temperature (based on the substance involved) below which a superconducting substance conducts electricity with zero resistance; as a result, the t
