Answer:
(A)Here is a translation of Newton's First Law: · “The first law states that a body remains at rest or in uniform motion in a straight line unless acted upon by a ...
(B)Solution: Two effects of a force applied on a body are: (i) It can change the state of movement of the body on which force is applied, i.e. it can move a stationary object or stop a moving object. (ii) It can change the shape and size of an object.
(C)Force is a push or a pull acting on an object which changes or tends to change the state of the object. For example: Actions, like opening the door, lifting a bag, kicking a ball, pulling a drawer, pushing a box are some of the tasks we do every day.
(D)Force is a push or a pull acting on an object which changes or tends to change the state of the object. For example: Actions, like opening the door, lifting a bag, kicking a ball, pulling a drawer, pushing a box are some of the tasks we do every day
(E)Magnetic force:Computer hard drives use magnetism to store the data on a rotating disk. ... Frictional force:Quite often uses of friction can be seen from how things would be without friction. If there was no friction, you would not be able to walk, drive a car, or hold objects. Pens and pencils would not work.
(F)A body is said to have uniform velocity when its velocity does not change with time. A body has variable velocity when its velocity changes with change in time. Note that a body is said to have uniform velocity only if both its magnitude and direction does not change with time.
(G)If a body travels equal distances in a particular direction, in equal intervals of time, the body is said to be moving with a uniform velocity. (H)Example: The rain drops reach on earth's surface falling with uniform velocity. A body, once started on a frictionless surface, moves with uniform velocity
