Zig-zag motion involves changing direction frequently and moving in an irregular pattern, while back and forth motion involves moving in a straight line in one direction and then reversing direction to return to the starting point. Zig-zag motion covers more ground and can be less predictable compared to the more linear back and forth motion.

Why does smoke particles move in zig-zag?
Smoke particles move in a zig-zag pattern due to the random and turbulent nature of air flow. As the particles are carried by air currents, they are constantly buffeted by molecules in the air, causing them to change direction frequently. This results in the erratic, zig-zag motion that is commonly observed.
Do electrons move in straight lines?
Electrons do not move in straight lines. They follow a path that is influenced by electric and magnetic fields, as well as other factors such as collisions with atoms or molecules. The motion of electrons is often described as a random, zig-zag path, especially in materials with high resistance.
Does light travels in a zig zag?
No, light rays travel in straight lines. When light enters a medium with different optical density, such as air to water, it may appear to change direction due to refraction, but it still travels in a straight line.
Why is a stretchy elastic band stretchy?
Elastic bands are made of a material that can stretch and return to its original shape due to its molecular structure. The molecules can be stretched apart when force is applied, and they snap back into place when the force is removed. This gives the band its stretchy property.
Why is Brownian motion important to the study of Physics and what are at least 2 examples of Brownian motion in real life situations and the importance of them?
Molecules in a fluid move constantly, freely, randomly, in all directions and with all possible velocities. This erratic motion of the molecules causes them to collide with anything in their path. when pollen grains are suspended in a gas, they fill a resultant force i particular direction and moves to another position, where it has to face same force again. For example, dust particles will be bombarded by the molecules moving at high speeds, causing them to have a zig-zag motion. Brownian motion also takes place in molecules in a liquid, but to a less obvious extent than in a gas.
