CG Board Class 6 Science Motion, Force And Pressure Notes / Textbook Exercises / Question Answers as well as Additional Question Answers from the Chapter.
Objects and Motion
Objects around us can be in a state of rest or motion.
Motion can be straight-line, circular, rotational, oscillatory, periodic, or non-periodic.
Types of Motion
Straight-line motion can be uniform or non-uniform.
Speed is the distance traversed by a body or object in unit time, with the SI unit being meter/second.
Force
Force is a push or pull applied to any body.
A force can change the speed, shape, or size of an object.
The SI unit of force is Newton (N).
Force can be classified into mechanical, gravitational, magnetic, electrostatic, and frictional force.
Pressure
Pressure is the force exerted on a unit area.
Fluids (liquids and gases) exert pressure.
The SI unit of pressure is Newton/meter² (Pascal – Pa).
Atmospheric pressure is about 100 kilopascals (kPa).
