Question

.What are the two types of forces
Define contact force
.Name any two non contact force
The force resulting due to the action of muscular
What is the SI unit of force

Answer 1

Answer:

1. There are 2 types of forces, contact forces and act at a distance force.
2. A contact force is any force that requires contact to occur. Contact forces are ubiquitous and are responsible for most visible interactions between macroscopic collections of matter. Pushing a car up a hill or kicking a ball across a room are some of the everyday examples where contact forces are at work.
3. Examples of Non-Contact Forces are:

• Gravitational force.
• Magnetic force.
• Electrostatics.
• Nuclear force.

4. The force caused by the action of muscles in our body is known as muscular force.

5.The SI unit of force is the newton, symbol N.

Answer 2

Explanation:

1.What are the two types of forces

Answer

There are 2 types of forces, contact forces and act at a distance force. Every day you are using forces. Force is basically push and pull. When you push and pull you are applying a force to an object.

2

Define contact force

Contact forces are forces that act between two objects that are physically touching each other.

3

Examples of Non-Contact Forces are:

Gravitational force.

Magnetic force.

Electrostatics.

Nuclear force.

4

the the force of due to the reaction of muscular force is known as contact force
