Question

classify the following forces into contact (CF) and non contact (NCF) force
1. gravitational force
2. frictional force
3. Muscular force
4. magnetic force
5. electrostatic force
6. collision force ​

Answer 1

Answer:

Gravitational Force- Non Contact

Frictional Force- Contact

Muscular force- Contact

magnetic force- Non Contact

electrostatic force- Non Contact

collision force - Non Contact

Answer 2

Answer:

Explanation:

The forces which act on bodies when they are in physical contact. are called contact forces. For e.g. frictional force and force exerted on two bodies during a collision.

The forces experienced by bodies even without being physically touched are called the non-contact forces. For e.g. Gravitational force and Electrostatic force.

Contact force: frictional force, muscular force.

Non-contact force: gravitational force, magnetic force, electrostatic force, collision force.
