III. Answer in Detail
1. Differentiate mass and weight.
2. Explain different types of motion
3. Explain Brownian movement with suitable diagram.
Answers
Explanation:
1.Mass =The amount of matter contained in a body is called mass.
Weight=the force with which body is attracted towards the earth is called weight.
that's all i know sorry
Answer:
Qno 1.In scientific contexts, mass is the amount of "matter" in an object (though "matter" may be difficult to define), whereas weight is the force exerted on an object by gravity.
Explanation:
Qno.2.Rotary Motion: A special type of motion in which the object is on rotation around a fixed axis like, a figure skater rotating on an ice rink.
Oscillatory Motion: A repeating motion in which an object continuously repeats in the same motion again and again like a swing.
Linear Motion: A one-dimensional motion on a straight line, like an athlete running on a straight track.
Reciprocating Motions: A repetitive and continuous up and down or back and forth motion like a needle in a sewing machine.Curvilinear Motion Rectilinear Motion
When an object moving in translational motion follows a curved path it is known as Curvilinear motion. An object moving in translation motion opts a straight-line path, then it is known as Rectilinear motion.
Qno. 3.Brownian Motion: Upon dropping some tiny particles in the fluid and observing it with a microscope, we see the zig-zag movement of the particles which occurs due to the collision with the particles of the fluid. This phenomenon is known as. Brownian movement of the particles.
