Lighting is an electric sprak on huge scale

2Thank You

Yogita Ingle 7 years ago

Lightning is observed as a bright streak of light during a thunderstorm. Lightning is always accompanied by the sound of thunder. The transfer of charge from clouds to the earth or from cloud to cloud is called lightning. In simple words; lightning is an electric spark which happens on a grand scale in the sky.

During a thunderstorm, the air currents move upward and water droplets move downward. These movements take at very fast pace and it results in separation of charges in the clouds.
The positive charges accumulate at the upper edges of the clouds and the negative charges accumulate at the lower edges of the clouds. Scientists are yet to understand the exact reason for this.
At the same time, the ground becomes positively charged.

Explain why the sliding friction is less than static friction

Posted by Yamuna Yamms 7 years ago

CBSE > Class 08 > Science

1 answers

Yogita Ingle 7 years ago

The sliding friction is less than static friction because of the interlocking of irregularities in the two surfaces. When the object starts sliding the contact points on its surface, do not get enough time to lock into the contact points on the floor.
So the sliding friction is slightly less than the static friction.
