Movement of an object from one place to another is called motion. We see many things around us are in motion. Motion takes place when force is applied. For example, a boy throws a ball. Movement of the ball takes place due to the force exerted by the boy.
Boy exerts force to throw ball
Different Types of Motion
There are three types of motion. They are uniform motion, non-uniform motion and circular motion.
If a body travels equal distance in equal interval of times then it is called uniform motion. For example, a car travels first 30 kilometres in one hour and next 30 kilometres again in one hour and so on then we say that car has uniform motion.
Car moving with uniform motion
Non Uniform Motion
If a body travels unequal distance in equal interval of times then it is called non uniform motion. For example, a car travels first 30 kilometres in one hour and next
30 kilometres in half an hour then we say that car has non uniform motion.
Car Moving With non-Uniform Motion
If a body travels on a circular path then it is called circular motion. For example, movements of a merry go round.
Merry go round moves in circular motion
Motion takes place when ___________ is applied.
(c) Both Force and Mass
(d) None of these
(e) All of these
For moving any object form one place to another we need to apply force.
Which one of the following is a solid object?
(d) All of these
(e) None of these
Computer is a solid object. Therefore, Option (c) is correct and rest of the options is incorrect.
Anything which has mass and occupies space is called matter.
Matter exists in three different forms, i.e. Solid, Liquid and Gas.
These three forms of matter are called the stages of matter.
