02. An object is dropped at the top of an inclined plane which of the following is true for the motion of that object
Answers
An object placed on a tilted surface will often slide down the surface. The force of gravity (also known as weight) acts in a downward direction; yet the normal force acts in a direction perpendicular to the surface (in fact, normal means "perpendicular")
At the top of the incline, the mass is still at rest, so the Mechanical energy . At the bottom of the incline, the gravitational potential energy, would be all converted to kinetic energy, , where the object has attained its maximum speed. So the Mechanical energy, . Examples are ramps, sloping roads, chisels, hatchets, plows, air hammers, carpenter's planes and wedges. The most canonical example of an inclined plane is a sloped surface; for example a roadway to bridge a height difference.
