Newton`s First Law of Motion
... Mass is NOT volume, the measure of space that an object takes up Mass is NOT weight, the force of gravity on an object Mass is a measure of the inertia that an object exhibits in response to any effort made to start it, stop it, or otherwise change its state of motion Mass and weight may not ...

... Lift- causes the airplane to rise into the air. Lift must be stronger than the weight pulling on the plane in order for it to fly. Drag is a pull that slows the plane down. Forces can crush, stretch, or twist objects and deform them. The harder a substance is, the more force it takes to change its s ...

... For object sliding on a smooth inclined plane • The acceleration depends on the inclination of the plane only. It does not depend on the mass. Objects of different masses slide on the inclined plane with the same acceleration. • The acceleration always points down-slope, independent of the directio ...

... Since the individual angular momentum can change, the total angular momentum of the system can change. Both internal and external forces can provide torque to individual particles. However, the internal forces do not generate net torque due to Newton’s third law. Let’s consider a two particle system ...
