In this figure the Dragon Khan rollercoaster in Spain’s Universal Port Aventura Amusement Park is shown. There are mostly curved paths in the rollercoaster. Near to the rollercoaster there is the track of rollercoaster cart under a bridge. There are some trees near the track.
Everyday motion that we experience is, thankfully, rarely as tortuous as a rollercoaster ride like this—the Dragon Khan in Spain’s Universal Port Aventura Amusement Park. However, most motion is in curved, rather than straight-line, paths. Motion along a curved path is two- or three-dimensional motion, and can be described in a similar fashion to one-dimensional motion. (credit: Boris23/Wikimedia Commons)

The arc of a basketball, the orbit of a satellite, a bicycle rounding a curve, a swimmer diving into a pool, blood gushing out of a wound, and a puppy chasing its tail are but a few examples of motions along curved paths. In fact, most motions in nature follow curved paths rather than straight lines. Motion along a curved path on a flat surface or a plane (such as that of a ball on a pool table or a skater on an ice rink) is two-dimensional, and thus described by two-dimensional kinematics. Motion not confined to a plane, such as a car following a winding mountain road, is described by three-dimensional kinematics. Both two- and three-dimensional kinematics are simple extensions of the one-dimensional kinematics developed for straight-line motion in the previous chapter. This simple extension will allow us to apply physics to many more situations, and it will also yield unexpected insights about nature.

what is Linear motion
Hamza Reply
straight line motion is called linear motion
then what
linear motion is a motion in a line, be it in a straight line or in a non straight line. It is the rate of change of distance.
your are wrong Saeedul
Linear motion is a one-dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimension
is a one-dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimensions.

a wave which require material medium for its propagation
The S.I unit for power is what?
Samuel Reply
Am I correct
it can be in kilowatt, megawatt and so
OK that's right
SI.unit of power is.watt=j/c.but kw.and Mw are bigger.umots
What is physics
aish Reply
study of matter and its nature
The word physics comes from a Greek word Physicos which means Nature.The Knowledge of Nature. It is branch of science which deals with the matter and energy and interaction between them.
why in circular motion, a tangential acceleration can change the magnitude of the velocity but not its direction
Syafiqah Reply
because it is balanced by the inward acceleration otherwise known as centripetal acceleration
What is a wave
Mutuma Reply
Tramsmission of energy through a media
is the disturbance that carry materials as propagation from one medium to another
mistakes thanks
