what is importance of gravitational force
Answers
Gravity is very important to us. We could not live on Earth without it. The sun's gravity keeps Earth in orbit around it, keeping us at a comfortable distance to enjoy the sun's light and warmth. It holds down our atmosphere and the air we need to breathe.
Answer:
The importance of gravitational force are as follows:
• Gravitational force is the force that pulls the objects towards the surface of Earth.
• Gravitational force also performs as a very important role in our daily life as it enables us to walk on the surface of Earth.
• Also, gravitational force is a non-contact force since no physical contact is applied in a gravitational force.
Justification:
Firstly, we need to understand that what is meant by contact and non-contact force.
✭ Contact force :
→ A force which requires physical contact between two bodies, is called as a contact force. Some examples are muscular force and frictional force.
✭ Non-contact force :
→ A force that does not requires any physical contact between two bodies, is called as a non-contact force. Some examples include electrostatic force, magnetic and gravitational force.
Let's take an example to understand it in a easy way!
↦ When a body falls towards the Earth, then does it requires any physical contact between the two bodies acting upon? Of course the answer is no. So, therefore gravitational force is a non - contact force.
